FR2840399A1 - AUTOMATIC INDIVIDUAL WEAPON WITH ELECTRONIC MANAGEMENT AND AMMUNITION WITHOUT CASE - Google Patents

Abstract

The invention relates to a personal weapon, intended for the semi-automatic and automatic firing of caseless ammunition, provided with an electronic firing control with biometric identification of the shooter. The weapon comprises a device for sealing the chamber based on the use of segments or corollas with mechanical bore variation or gas pressure. A delay in the opening of the cylinder head assembly can be introduced by the use of tenons driven by the propellants. A tandem magazine compartment sequencing device takes advantage of the volume reduction offered by the ammunition formula to double the firepower of the weapon. A removable lock makes it possible to completely block the allasse, trigger, magazine and disassembly lock for absolute safety of the weapon. A telescopic barrel extension device increases the power of the ammunition and a gas borrow from the chamber allows firing to be stabilized.

Description

DOMAUNETECMLQUEDELINVENTION The present invention relates to a weapon

  small caliber, defined in such a way as to guarantee its inviolability and use by authorized personnel only, in order to ensure complete control of its detention. For this purpose, it comprises a morphological identification device (fingerprint) of the shooter couple to a device for firing an electric ammunition without a case. It is clear that this formula frees the weapon of any mechanism of electromagnetic lock easy to bypass as much as the use of conventional ammunition

  a central percussion and case that everyone can easily recharge at home.

  The present weapon is therefore addressed in priority to governments and agencies concerned with the tight control of detention and the fight against the proliferation of arms. Indeed, the production of ammunition without oil according to the invention can not be obtained in a particular workshop and requires a technology that senls them

  Governments have the power to authorize and control.

  The weapon also takes advantage of the small size that characterizes the ammunition to significantly increase the firepower through a compartment loader. This major asset constitutes a new deal in the field of armaments since the application of the principle of the invention makes it possible to increase in proportions outside the

common firepower.

  The very principle of the weapon allows the development of a security of dhente particularly easy to implement and innovating: contradiction. Its principle removes any coordination error, especially in the event of stress, and its safety formula is the only one that can remain permanently engaged and be released a fraction.

second before a reflex shot.

  The weapon finally and above all has an especially reliable and simple chamber munition chamber system, a volumetric augmentation system of this chamber as well as a device for the total prohibition of

  shooting, disassembly, breech movement and loader.

  The weapon thus defined comprises: - a central computer, - a clock, an electrical source (battery, battery ...), - a morphological identification device of the shooter, - an electric firing device, - a device cartridge ignition / ejection device; - an extractor lifting device; - a mechanically expanding chamber or segment gas pressure device; - a propellant borrow device at the periphery of the engine. the piston head, - a device for borrowing propellant gas at the firing bowl, - a cylinder / gun barrel securing device, - a magazine with two compartments, - a sequencer device for the magazine compartments. - a firing stabilization device, - a counterfeit safety device, - a telescopic gun, - a key locking device, - a double recovery spring of one or more conductor wires,

  - a connection port to a computer.

STATE OF THE TECHNIQUE [QUE

  US Patent 5,603,179 A (Adam HEIKO B) of February 1997 describes a mechanism of security of detente weapon by identification of the fingerprint of the user. The coordinates of the wind imprint contained in a cassette unfortunately removable and therefore conducive to a quick change all without protection since no

  barrier of inviolability by access code or similar is not provided.

  1 0 The device is intended to be mounted on a ammunition weapon has mechanical percussion percussion. A device of the electromagnetic type (electromagnet), connected to the identification device, ensures ['prohibition of

  percussion attempt that identification is not assured.

  It is clear that such a system is particularly easy to circumvent since it is sufficient to remove the blocking electromagnet to free the weapon from its selective capacity of tin authorization.

  The author also provides a switch powering the weapon not conducive to a reflex shot.

  Finally, the integration of the selective identification device entails, given the remanence of the classics

  linkages and other transmissions and the addition of the new components (cassette or card, electronic

  anant, batteries ...), an increase in volume leading to an oversizing of the weapon at the level of

  Handle detrimental to its use by small hands.

  The present patent, on the other hand, describes a fully electronic weapon whose elements (computer, batteries electronic card ...) ensuring the complete management of all the functions including identification of the lodges in the single cylinder head causing no increase of volume. The absence of any removable card and other lock

  mechanical guarantee the inviolability of the weapon.

  There are many attempts to solve the problem of simplification of ammunition by removing cases. Most of the formulas proposed to date are concentrated on the more or less complete combustion of

  and to the telescoped design of ammunition.

  Dynamit Nobel Patents 86 13507, WO 93/18364 & WO 96/17220 disclose a complex small-caliber telescoped ammunition formula with respect to the formula selected for the present invention. These munitions have the particular disadvantage of ejecting a plastic closure cap at the end of this patent. This patent proposes an improvement of the telescoped design of the ammunition without a case with, in particular, a particular housing of the electrical primer allowing to reduce the clutter of the ammunition and suppressing

  any need for a headdress or other protection.

  The use of ammunition without a case also causes the need to obtain a perfectly sealed ammunition chamber during the combustion of the propellant. Numerous formulas have been patented and tested without apparent success, attributable without delay to the maintenance of classical mechanical percussion and to the complexity of the sealing devices retained. US Pat. No. 3,345,770 A (Scanlon JJ), dated October 1967 , proposes an atom destined to the shooting of ammunition without case which presents the peculiarity of not to have a groove of extrsation. The author is responsible for a chamber whose tightness is provided by a mandrel having a plastic seal located between two open segments. The author does not specify the leaks inherent in the opening of these segments whose

  section is square as shown in their drawings in Figures 2 and 3.

  Lines 22 to 24 of the 2 illuminate more on the principle of tightness retained by Scanlon. Indeed, they clearly state a diameter of the O-ring greater than the size of the piston since the neck rounded intone is supposed to compress it to put it in format, all without prejudging the firottements causing delays at the closing the breech, or a rate of fire altered with risk of blockage. The seal is therefore clearly based on the plastic seal that the only segment of head can not fully protect assaults

burning gases.

  The choice of the plastic material (neoprene, teflon color 2 line 18) raises questions as to the temperature resistance of this joint when it is found that these materials have a melting point of about 250 ° C. for the most part.

  resistant and that the gas temperature reaches 1800 C.

  Since the weapon is intended for automatic firing, it is highly likely that the heating of the chamber and the segments will not quickly lead to softening, cooking or melting of the seal with the risk of fouling.

  the knuckle, jamming of the weapon then rupture with escape of the gases towards the shooter with the key.

  To increase the longevity of the O-ring, the author should have resorted to two segments joined to each other and placed before the plastic seal (and not separated by this seal, the rear segment providing no protection) and indexes so that their openings are not facing each other. This solution would have the advantage of eliminating gas leakage by opening the head segment and improving the conformity of the segments.

  with the cylinder without however ensuring a real tightness.

  However, the presence of the segments flanking the joint and undergoing the same efforts may even suppose that their diameter is necessarily greater than the bore of the piston otherwise they would have no reason to be, the

  protection of the gas against the burning gases being then assured by the piston itself.

  Curiously, Scardon JJ does not mention the consequence of this oversizing of the diameter of the segments leading to an inevitable scraping of the inlet of the neck of the supply rail by the square section (see Figure 2) of the cutting edge acting like a plane. . This effect will manifest itself regardless of the profile

  the neck (rounded, conical ...) and the angle of attack, as small as it is, since it presides over the principle of the plane.

  The putting out of use of the weapon is then inevitable, the shooter having no possibility to compress the segments inside their home to promote ['introduction of the chuck in his room, any further attempt to

  forward movement of the bolt ending in a blockage.

  More hazardous still is the risk of destruction of ammunition by planing the segments. We can easily imagine the effects of scraper segments on a compact powder cake. Without delay, in order to mitigate this risk, the author reports a busc on the lower face of the bolt (level 44 of FIG. 2), the function of which is obviously to produce an impression of the cartridges during the recur of the head of the bolt. cylinder head to prevent any contact of the segments with said cartridges. Moreover, the author does not seem to perceive the consequences of the necessary connection which the production of this cartridge has on the cartouches stacked in the magazine when the cylinder head is moving, with the risk of jamming and jamming of the cylinder head. breech and destuction of powdered bread

ammunition.

  In addition, this busc can not in any case avoid contact segments with the base of the ammunition despite the presentation of the cartridges under a strong angle caterer. To be convinced of this it suffices to simulate the recur of the breech to find that there is necessarily contact, once the busc discover the base of said ammunition,

  segments with the powder loaf. The destruction of the latter by pulling / scraping is then very likely.

  Finally, no device for extracting a chambered cartridge is provided, exposing the user to the jamming of his weapon in case of defective ammunition. It should then remove the magazine, open the bolt and push from the barrel entrance with an ad hoc rod to try to extract the cartridge with the danger that we are

case of long fire.

  The author does not specify anything about the length of the waterproof chamber yet determining for the safety of the weapon: a room too race irretrievably drives a too hasty opening exposing the shooter

  and the shelling gas magazine ammunition of the detonation.

  In conclusion, the patent Scanlon weapon is intended to repetition by mechanical percussion ammunition without case corresponds to an incomplete study or the author proposes a formula of dangerous tightness based on the use of a fragile joint composed of segments to irrational scheduling (a segment behind the plastic seal), without prejudice to their inevitable planing of the introduction neck as ammunition with jamming of the key weapon, all without prejudice to the absence of extractor which exposes the user in case of cartridge failure. This patent, on the other hand, mitigates these design errors by mechanically causing or

  gas uniform expansion of leak-tight segments thanks to the adoption of a suitable format.

  This formula also guarantees a lack of jamming during the forward movement of the cylinder head and an absolute reliability of temperature resistance. This patent finally ensures the firing of electric ammunition as well as

  Cartridge extraction has a will, which can not ensure the patent Scanlon J.J.

  Patent FR 2 308 076 A (CIVOLAN! Bruno) of November 1976 describes a weapon percussion system using self-propelled projectiles equipped with peripheral primers as described in the Italian patents

N 932,381 and 972,058.

  These projectiles constitute real ammunition without holster but suffered from serious problems of stability on trajectory and precision attributable to the deformation caused by the percussion on the cylindrical wall of the projectile. The delay in opening the chamber is obtained by recur of a closing pivot, similar to the mandrel of US Pat. No. 3,345,770, of the same diameter as the projectile and whose length is such that the opening intervenes.

  after the barrel projectile exit.

  1 0 The sealing of such a room is not evoked by the author who affiuble the chuck, in the accompanying figures,

  radial grooves not mentioned in the description.

  It is clear in any event that the mere presence of these grooves can not ensure proper sealing of the gas, or, if they received sealing segments, prevent blockage of the bolt during the forward movement,

  making the weapon dangerous to use.

  Finally, no mention of an extractor is made in the description except on the attached sheets, leaving a

  to think that the author, like J. J. Scanlon with his US Pat. No. 3,345,770, has not been able to solve this crucial problem.

  The principle of this weapon is limited to a functioning in automatic since there is systematic percussion of the projectile of the closing of the room. However, the displacement of an inertial mass towards the front at the moment of firing results in an inexorable disturbance of the line of sight which is prejudicial to accuracy. Weapons (MAT 49, UZI) operating according to this principle are too imprecise and either withdrawn from service or modified (UZI) for

  adopt a percussion mode cartridge chambree.

  The present patent describes, on the other hand, an ammunition without a particular case precisely because the projectile is affected, during firing, by any incision or deformation likely to impair its precision. The weapon thus proposed

  has a perfect sealing chamber with a defective ammunition extractor.

  The patent FR 849 727 A (Steyr-Daimler-Puch Aktiengesellshaft) of February 1939 describes a weapon for the automatic firing of ammunition with socket with systematic percussion at the end of chambering of the ammunition. This system suffers from the same drawbacks as those of patent FR 2 308 076 A (Bruno CIVOLANI), namely a brutal advance of the cylinder head with chambering of the cartridge at the time of firing, reputed imprecise because of the masses set in motion. For information this formula has been developed for the machine guns of fac, it is to avoid self-ignition (cook-offl cartridges fired in a burning chamber, that is why the ammunition is introduced only to be systematically struck of the The breech / barrel joining system of patent FR 849 727 is controlled by the recur pressure gas borrowed downstream of the barrel, a

  piston integral with the firing pin actuating in turn the blocagelblocking mobile locks.

  This system is particularly complex since it relies on the use of tenons mus mechanically by the movement of the firing pin with the inevitable problems of wear on the edge that this solution entails. If the control of the drawer piston ensuring the movement of the firing pin is effected by borrowing gas, the principle of this patent requires a bulky architecture substantially increasing the size of the weapon as much as its weight due to the number of elements ( the cylinder and piston parallel to the cylinder head, ducts ...) put in play. Thus, does this solution require a long pipe of gas sampling running along the barrel so

  to borrow the gas at the end just before the exit of the ball.

  Even more surprising is the absence of an extractor in the description than on the enclosed boards, leaving a

  that the author, like J. J. Scanlon (US Pat. No. 3,345,770) and CIVOLANI Bruno (patent FR 2,308,076 A), has not been able to solve this crucial problem with his chamber formula. We will not revisit the effects of a

  such negligence if a munition were to fail.

  Consequently, the patent F 849 727 shows a complexity of the mechanical locking system with underlying wear, a number of parts, a maladaptation to ammunition firing without a case, an inaccuracy

  resulting from the late chambering of the ammunition and an inability to extract a failed munition.

  The present patent describes, on the other hand, a locking system breech / barrel studs driven by the gas directly borrowed at the level of the tin slot This formula eliminates any pipework, piston, shirt and other additional accessories, proves particularly light, easy and economical to implement

  work (a simple milling is enough), and entails no increase of the congestion.

  This arrangement has the advantage of avoiding any risk of blockage that may result from the modification of a tenon due to wear. Finally, the proposed formula uses ammunition without i that can be

  extracted in case of failure what the patent FR 849 727 is unable to realize.

  Patents 79 06 106, 83 07602 & 83 07603 Heckler & Koch describe a rifle using ammunition without case whose chamber sealing is provided by a particularly complex device based on a 180 rotation of the chamber. Cartridge feeding is by gravity, lending the flank to many problems when the weapon is in motion. The rotation of the chamber (borrowed also from the old principle of the water taps) does not guarantee any tightness to propellant gases free to go back to the supply channel. This formula

  This resulted in a great complexity of the rotation mechanism of the chamber and was abandoned.

  Patent FR 2,082,183 A (Fabrics Meca Ste Mo) of March 1970 describes a safety device blocking the relaxation of a weapon under the effect of a pressure exerted at the rear of the tail of relaxation and to [' before causing ['engagement of a transverse unlocking pusher. This system is based on a "floating" mount of the trigger that has no axis of rotation but only supports via bosses: this formula prohibits any possibility of adjustment of the duration of relaxation and limits its use to it is mounted on conventional percussion weapons without being able to meet the requirements of electric firing weapons. The presence of the lock on a side of the weapon also prohibits any possibility of ambidextrous use and, at the same time, deprives the shooter of the

  perception of this security when he approaches the weapon of the side opposite the one with the pusher.

  The present patent, on the other hand, comprises a relaxation safety device compatible with the electrical mechanisms and of perfectly ambidextrous use, implemented by rotation towards the front of the stretching tail.

  having the advantage of being immediately visible and this, whatever the side where we look at the weapon.

  US Patent 5,705,763 (Jorge A. LEON) of January 1998 describes a device for transforming a semi-automatic weapon into an automatic weapon. Addressing only semi-automatic weapons with mobile bolt and mechanical percussion, this device allows a selection of the shot by a particular positioning of the tail of relaxation with the help of a pressure exerted in the arnere and towards [ beforehand to produce a tilt. This device does not provide any security function, its sole purpose is to produce a repetitive automatic firing when the tail

  of relaxation is in a certain position.

  This patent, on the other hand, proposes the use of a movement towards the front of the detent tail in order to

  block said relaxation and is not to be confused with that of a semi-auto / auto selective shot.

  U.S. Patent No. 4,833,808 A (Stravan TRAVIS) of May 1989 discloses a recoil damping system having a co-cylindrical barrel mass whose forward projection is effected by borrowing gases. This device, intended to be mounted at the end of the barrel, weighs the weapon and modifies its balance and its length. It also requires a perfect harmonization of the pitch of its stripes with those of the barrel in a particularly delicate assembly that the author does not address despite its important and dangerous character This device limits its effect to that of an antirecure whose effectiveness is closely related to synchronization with the

  recur of a bolt that the author does not address.

  The present patent, on the other hand, stipulates: - a mechanism of short recur of the barrel via a damping effect aiming to allow a canonical solidarity to destabilize the opening, - a device of telescopic extension of the barrel aiming at increasing the power of ammunition by realizing

an expansive room.

  In addition to a compensation effect of recur certau, these devices ensure above all a function different from that of the

TRAVIS patent.

  DE 90 17 151.9 U (FIELD R.C.) of December 1990 discloses a compartmental tandem loader for use of ammunition without a case. The sequencing of the different compartments is carried out by means of rockers operated by the same ammunition beginning of each plateau, the end of the preceding. This device has several disadvantages, namely: - impossibility of use with ammunition profile other than rectangular, - impossibility to supply by hand the compartments from the top of the charger, requiring a specific device impractical and charger power supply by the teas, risk of blocking the arrne by jamming the feed pusher (7) in the loader, thus preventing any withdrawal to said loader, weakens rockers (4) pivoting on an axis arranged within a partition wall. low thickness 1 0 may entail risks of containment, - need to supply the compartments in a precise order (before, middle pais back) under penalty of blockage by the rocker or compartments that would not have been supplied respecting this order,

  - limitation of use of the charger to the only weapon including a push of supply.

  The present patent, on the other hand, describes the operation of an ammunition magazine without case with two compartments easily and independently available whose sequencing is provided by a mechanism

  located on the weapon that does not require any power button with its inherent risk of blockage.

  The invention consists of a weapon specifically adapted to ammunition firing without a semi automatic and automatic case. The use of these ammunition requires an electrical ignition device and chamber sealing

  specific as defined below.

  DESCRIPTION OF THE AMMUNITION (BOARD 1/28, FIG 1, I b, 2 & 2 b>

  The weapon is suitable for firing any type of ammunition without a case of various calibres whose general shape is cylindrical and has an extraction groove at the rear. Thus, the munition can be indifferently composed of a projectile a '' front (Fig. 1/1 & 1/2) torque to a solidified propeller (2) a l'arrière or the telescoped type (Fig 2/1 & 2/2, n 13), ie composed of a beautiful (13) embedded in a gangue (14) of solid propellant comprising a

  extractor claw engagement groove (6) at the rear and an opening at the front of the same gauge as the bullet.

  Said beautiful comprises a rear bowl (15) containing an agent (5) for initiating the propellant and its

  position in the gangue is such that it can be closed by a cap (4) conductor and fuel.

  This arrangement provides excellent protection of the primer against any risk of inadvertent firing by making a cage type Faraday anti-radiation. The exceptional compactness of the ammunition thus obtained will be

  profitably to increase the firepower.

  Note: a variant of ammunition (pi 1/28, fig 1/2) with propeller coupling at the rear can be realized by extending the cap in a skirt (3) covering the thruster and in particular the extraction throat to prevent any risk of deterioration to said thruster in case of violent ejection of a munition, especially when the inertia of this rear is strong (large caliber for example). Any other formula that shields the extraction throat

  would participate in the same protection.

  Modes of manufacture of the ammunition. The thruster is either mold at the back of the beautiful or surrnoule around the beautiful akin to achieve the gangue (14) in a senle foist The primer is housed preliminarily or after ltoperation overmoulding, opercule or conductive pad is affixed in order to guarantee the tightness of the ammunition. This formula has many advantages in terms of reducing production cost as well as sealing. The addition of a trac, ante composition at the bottom of the skirt will make it possible to detect the ammunition sensibly from the rear area, accentuating the discretion of the armor. DESCRIPTION AND FUNCTION OF THE WEAPON (Pbnda 2 d 2828) The chosen arrn Demonstration is preferentially but not exclusively an automatic pistol, the principle of 1'invention can be extended to all calibers and types of weapons. The weapon functiome according to a principle of tightness of engine by cylinder head piston with delay at the opening by recur said piston. This principle

  Sealing can be adapted to any caliber of weapons (including artillery).

  Conventionally designed weapons use ammunition with the latter ensuring the sealing of the chamber during the course of time separating the firing of the barrel ammunition exit. The delay in opening is then generally obtained by blocking the case in the hinge via a fixed fixed link

  during the journey of the ammunition in the barrel.

  In the case of use of ammunition without case according to the invention, the sealing and the delay to the opening, necessary for an optimal performance of the weapon, are simultaneously ensured by one or more segments located on the periphery of the weapon. a

  piston (18), integral with the cylinder head, the recur is progressive in a chamber (62) sealing.

  This chamber (62) is in the extension and contiguous to the ammunition chamber (61) which comprises as required: - a housing for receiving and lifting (S9) of the attachment device (extractor) of the throat of the ammunition - a propellant borrowing event (90) located near the funnel inlet, and said breech piston chamber (62) including, if necessary, housing (56 bis)

  securing the barrel with the breech piston.

  This system guarantees an absolute security by designing a perfectly sealed chamber during the shooting, eliminating any potential of the own solution to the current solutions which are based on the fragile resistance of a case too

  often solicited during many reloads.

  In fact, ammunition weapons have shown a conceptual weakness generally ignored by users: the strength of the weapon during firing follows the principle of resistance of a chain, subordinate to that of the weakest link. However, the case is in many respects this weak link of the tin chain. The case not only plays the role of joint when it is pressed against the walls of the chamber at the start of the stroke, but it is still him who cash all the load of effort on its part back (base). But this behind is in the open on

  most current automatic weapons, conditioning the tightness of the firing chamber has its only resistance.

  The importance of the risk to users of a formula whose history is historically borrowed from the revolvers which, for their part, guarantee a better resistance is measured by the importance of the risk, since the base of the case is drowned in the cylinder and in support the total shield (or back of the barrel) of the weapon during the tin No user of automatic weapon is thus protected against the risks of fsure of the primer or rupture of wall of case, especially at the base, and the terrible liberation of burning gases which follows. The numbers

  accidents following successive reloading wind to testify.

  The weapon according to the invention ensures, on the other hand, a perfect firing safety based on a total charging technique of the ammunition by a piston in a chamber whose sealing is ensured by a self-expanding joint during the tin. thick steel walls of the piston and barrel incommensurate with

that of brass cases.

  The weapon uses, in a first mode of operation, a barrel fixed to the carcass and is therefore composed of a number of restraint pieces. This characteristic should have signi fi cant economic repercussions on the cost of production, maintenance, reliability and speed of operation. The weapon consists of two main parts (Sections 2 to 28/28):

  I - The slide assembly or bolt.

  SEALING OF THE CHAMBER First mode (Plate 4/28, Fig. 6/1 to 6/4): In a first embodiment of sealing, the mandrel skirt (20) has a receiving housing (42). a single segment (41) or a torque (Fig. 6/3) of segments (41 quarter & quint) sealing. This housing (42) constitutes a circumferential grooveDe of dimensions and section adjusted to thisDe (or) segment (s), is characterized in that it is hollow a second groove (42 bis) concentric and deeper , for the circulation of gases, comprising radial channels or orifices (40) communicating with channels (39) parallel to the central axis of the piston and opening into the cistern of a tin. The segment or the pair of sealing segments (41) , 41bis, quarter & quint) adopt a suitable section: square (41), symmetrical trapezoidal (41 bis) or asymmetrical (41 ter), in angle, square or any other adapted formula and wind preferentially but not exclusively of the type. open to bayonet (Fig. 6/2 & 6/3) or other and characterized in that, in the case of a couple, their mounting is concentric and superimposed, that is to say one inside the other and such that, retracted in the position of rest inside the throat the outside diameter of the segment or couple of segments remains below the bore or diameter of the piston. The curvature at rest of said segments is teD they marry perfectly, during expansion, the chamber

home of the piston.

  The superimposed segments, whose respective thicknesses and heights may be different, wind indexed so that the opening of one is not opposite that of the other. For this purpose, each segment comprises at the upper level of its opening a notch of dimensions corresponding to that of a pin (42 ter). The two segments wind together so that their respective notches cooperate with the radial pin (42).

  ter) housed in the reception throat and ensuring their indexing to 180.

  In the case of segments with a squared section or L, the indexing, preferably 180, can be obtained either by the presence of an element, of the ergot type, integral with one of the segments and cooperating with the opening of the segment. another which has a notch of reception of this element, the two segments being then mounted crazy in their throat of reception, either by the presence of pins (Fig. 6/12, 42 ter) lodged in the throat of reception in such a way that their head is protruding respectively in the bayonet opening of the corresponding segment. For this purpose, the openings

  will have a notch for accommodating said pin parties.

  Principle of operation: At the beginning of the blow the propellant gases take the ducts (39 & 40) which correspond and open on the inner face of the segment or segments (41, 41 bis, ter, quarter & quint) that the pressure, uniformly distributed by circulation in the second groove (42a), radially dilates which has the effect of pressing the segment or segments against the wall

of the room (62).

  The tightness is then ensured by the combination of: - the valve effect between a flat face of the (or) segments and the flank of the piston groove, - the contact between the peripheral door (under the pressure of the gases) uniformly circumferential segment (external) and cylindrical bore, - systematic shuttering by indexing in opposition to the segments of any window that may arise at the opening of the pair of segments during their expansion, and endure that the pressure of the propellants is exerted, that is to say during the journey of the beautiful in the barrel and

  simultaneous recur of the piston in his room.

  As the beautiful fate of the barrel the pressure drops instantly, the elasticity of the segment (or couple of segments) causes its retraction inside the throat and eliminates any risk of blockage of the piston at the entrance to the chamber. home (62) during the forward movement of the bolt. The expansion of the segment (or pair of segments) guarantees a

  perfect tightness of the ammunition chamber (61) during the only backward movement of the piston.

  In order to guarantee a long longevity to the segments, these will be realized in an elastic material (UE9P bronze,

  steel, cast iron ...) able to withstand temperature efforts.

  The friction of the segment in contact with the wall of the cylinder can be reduced by the adoption of a slightly convex outer surface (some 1/100 of a millimeter) and the application of self-lubricating treatment (nitride

  titanium, Diamond Like Carbon, amorphous carbon, molybdenum, graphite ...) idoine.

  This device constitutes a real regulating system of delay at the opening of room control by pressure of the gases. The advantage of this formula and allow the weapon to "digest" a large variety of ammunition of different masses, without the need to change the barrel or the mass of the breech, taking care however to verify that the recur length of the sealing piston in its chamber is sufficient for the type of ammunition considered. Second Mode (Plate 5n8, fg 6/3 & 6/5 to 6/8): In a second embodiment of sealing, the piston of the chuck having a housing (42) for receiving a segment or a pair (Fig. 6/3) of concentric and superposed sealing segments (encased one into the other) is characterized in that the housing (42) of the segment (s). (s) is hollow of a groove 1 5 (42 bis) concentric and deeper gas flow and that it has longitudinal splines (40 bis) in variable number and symmetrically distributed to the periphery of the piston head, said grooves (40 bis) opening at the front face of the piston to ensure the borrowing of gases to convey them to the throat

  (42 bis) with which they communicate.

  The segment or the couple (FIG 6/3) of sealing segments (41, 41bis, ter, quarter & quint) adopt an appropriate section: square (41), trapezoidal (41 bis), in angle, in equerre (41 quart & quint) or any other adapted formula and wind preferentially but not exclusively of the open bayonet type (FIG 6/2) or other and characterized in that they are, in the case of a couple, mounted concentric and superposed, that is to say one inside the other and such that, retracted in the rest position inside the receiving groove the outer diameter of the segment or pair of segments remains below the bore or diameter of the piston. The curvature at rest of said

  The segments are such that they perfectly fit, during the expansion, the piston chamber.

  The superimposed segments, whose respective thicknesses and heights may be different, may be indexed so that the opening of one is not opposite to that of the other. For this purpose, each segment comprises at the upper level of its opening a notch of dimensions corresponding to that of a goupiDe (42 ter). The two segments wind together so that their respective notches cooperate with the radial pin (42).

  ter) housed in the reception throat and ensuring their indexing to 180.

  In the case of segments with a squared section or L, the indexing, preferably 180, can be obtained either by the presence of an element, of the ergot type, integral with one of the segments and cooperating with the opening of the segment. another which has a notch of reception of this element, the two segments being then mounted crazy in their throat of reception, either by the presence of pins (Fig. 6/12, 42 ter) lodged in the throat of reception in such a way that their head is protruding respectively in the bayonet opening of the corresponding segment. For this purpose the openings

  will have a notch for receiving said pin balls.

  Principle of operation: At the start of the stroke, the propellant gases take the grooves (40 bis) peripheral of the piston head and exert a uniformly distributed pressure (symmetry of the grooves) on the upper lateral face of the (or) segment (s) (41, 41 bis, 41 ter, quarter & quint) as well as on their inner face by circulation in the groove (42 bis), which has the effect of pressing the segment (s) against the lower franc of the groove housing (42) and the (s) expand radially against the wall of the chamber (62) for perfect sealing. In order to facilitate its expansion under the effect of the pressure of the gases surrounding the piston head segment or segment torque may adopt a symmetrical or asymmetric trapezoidal profile (41 bis) (FIG 6/7, 41 ter) rises such that his inclined face is oriented toward

  Before the piston, the small side (or top) corresponds to the internal face of said segment.

  The receiving groove (42) will adopt a corresponding profile. From the initiation of expansion of the segment (or pair of segments) under the effect of the gases supplied by the longitudinal splines, the inclined lateral (trapezoidal) side of the segment (or pair of segments) traps the peripheral gases surrounding the piston assembly, the assembly then exerting a pressure which tends to press the segment (or pair of segments) in a perfectly uniform manner against the

  wall of the chamber and the flank of the piston groove thus ensuring tightness.

  As the beautiful fate of the barrel the pressure drops instantly, the elasticity of the segment (or couple of segments) causes its retraction inside her throat and eliminates any risk of blockage of the piston to the ltentree of the chamber

  (62) during the next forward movement of the bolt.

  In order to guarantee a long longevity to the segments, these will be realized in an elastic material (UE9P bronze, steel, cast iron ...) able to withstand the efforts of temperature. The friction of the segment on the wall of the cylinder can be reduced by the adoption of a slightly convex outer face (some 1/100 of millet) and the application of self-lubricating treatment (titanium nitride, Diamond Like Carbon, carbon amorphous, mobdene,

graphite ...) idoine.

  This device constitutes a real regulating system of delay at the opening of comrnande room by pressure of the gases. The advantage of this formula and allow the arride to dig a large variety of ammunition of different masses, without the need to change the barrel or the mass of the breech, taking care however to verify that the length recur of the sealing piston in his room is sufficient for the type of murrition considered. Third mode (Plate 6n8, Fig. 6/9, 6/10 & 6/11): In a third embodiment of sealing, the piston of the breech chuck is characterized in that the covette firing comprises light radial channels or radial crenels (40 ter), arranged symmetrically at the periphery, providing communication between the inside of said bowl and the circumferential groove housing (42) of a segment or a pair of segments ( Fig. 6/3) of concentric and superposed sealing, located around the piston at the level of the tin bowl The housing (42) of the segment (s) is of size and section adjusted to those of the (or) segment (s). In the case of use of radial lights, splines (40 bis) in variable number symmetrically distributed to the periphery of the piston head ensure the borrowing of gases at the front face of said piston to route them to the face back of the segment (or couple of segments) and combine their efforts with the gases of the firing bowl brought by the lights. A groove (42 bis) for the circulation of gases may be provided if necessary for operation combining the advantages of the first and second modes. The segment or the pair of sealing segments (41, 41bis, ter7 quarter & quint) adopt a suitable section: square (41), trapezoidal, angled, squared (41 quarter) or any other adapted formula and wind preferably but not exclusively of the open bayonet type (FIG 6/2) or other, in the case of a pair of concentric and superposed mounts, ie one inside the other, and characterized in they are retracted in the rest position inside the throat, the outer diameter of the segment or pair of segments remaining below the bore or diameter of the piston. The rest curvature of said segments is such

  that they marry perfectly, during expansion, the room of reception of the piston.

  Functioning principle: At the start of the stroke, the propellant gases borrow the lights or crenels (40 ter) peripherally from the firing bowl and exert immediately a uniformly distributed pressure (symmetry of the crenels and lights) on the internal circumferential (lateral) face of the segment or pair of segments (41 quarter & quint) and on the face (radial) which is directly perpendicular to it in the case of an angled or squared section, which has the effect of pressing the segment or pair of segments against the lower lenght of their groove housing (42) and expand them radially against the wall of the chamber (62) for a perfect tightness. No gas leakage through the openings of the segments during their expansion is possible since their concentric assembly, superimposed and indexed to 180

  ensures a mutual and automatic shutter.

  As soon as the good fate of the barrel the pressure drops instantly, the elasticity of the segments causes their retraction inside their throat and eliminates any risk of blockage of the piston at the entrance of the reception chamber (62) during the

  next move forward of the bolt.

  In order to guarantee a long longevity to the segments, these will be realized in an elastic material (UE9P bronze, steel, cast iron ...) able to resist the efforts of temperature and friction. A self-lubricating treatment (nitride

  titanium, Diamond Like Carbon, carbon morphine, molybdenum, graphite ...) can also be applied.

  This device also constitutes a real regulating system of delay at the opening of chamber controlled by gas pressure. The advantage of this formula and allow the weapon to "digest" a large variety of ammunition of different masses, without the need to change the barrel or the mass of the breech, taking care however to verify that the recur length of the sealing piston in its chamber is sufficient for the type of

ammunition considered.

  Note (plate 7/28, Fig. 6/12 to 6/14): the sealing of the segment expansion device according to the above modes can be increased by the use of two segments (41 quarter quint), profile preferentially but not exclusively in square or L and bayonet aperture (Fig. 6/13), concentric mountings and indexes to 180 of one another such that the race (or horizontal) branch of their section penetrates into a circumferential groove (42 quarter) hollowed on the lower edge of the receiving groove (42) of said segments and forrnant in particular a shoulder (42 10 quint). During the recur of the piston the friction of the outer segment (41 quint) on the wall of the receiving cylinder, the effect of which can be reduced by ['adoption of a slightly convex outer surface (some 1/1000 millirnetre) and [Application treatment (thermal, surface. ..) Suitable, exert a force tending to raise the segments to the piston head. The race section of the L-section of the inner segment (41 quarter) then abuts on the shoulder (42 quint) forrnant thereby sealing seal and preventing any leakage of gas circulating at the home of

1 5 segments.

  The inner segment (41 quarter) has a bayonet opening preferentially on the race branch of its section such that its opening (h) is inferieute the scope of said segment once dilated on the shoulder (42 quint). The outer segment (41 quint) has a bayonet aperture on its two branches so that perfect sealing is achieved by the segment stroke regardless of the friction effects tending to the surface.

  raise or press gases that tend to press against the lower side of the throat.

  The two segments thus mounted operate a tightness resulting from a double action: - vis-a-vis the peripheral gases of the piston blocked by the perfect contact of the outer segment and its bayonet against the wall of the chamber, - vis-a-vis the gases circulating in the back segments blocked by the valve effect provided by the race leg (or horizontal) segments (41 quarter quint) playing between the shoulder (42 quint) and the lower side face of the groove (42) according to: - The pressure of the gas pushes the two segments towards the teas of the piston and plate their race leg against said lower side face (42), the balonnette of the outer segment conjugated to the presence of the internal segment then prohibits any leakage, - the friction of the segment external (41 quint) against the chamber tend to raise the two segments whose branches strokes (horizon / ales) bear against the shoulder (42 quint) for

* achieve a perfect mechanical seal.

  The segment expansion device according to these modes, especially the latter since it ensures perfect tightness, is likely to find application in the field of the explosion engine. The piston head segment, in permanent support against the wall of the cylinder, would benefit from an increase in force of expansion and pressure against the lower flank of the groove of its housing, reinforcing the tightness of chamber and preventing any risk of vibratory panic, especially when the piston reaches the top dead center (inertia of

segment) at high speed.

  Fourth mode (Plate 8/28, Fig. 6/15, 6/16 & 6/17, 6/18, 6/19 & Plate 9n87 Fig. 6 / 2O): In a fourth embodiment, compatible with the any one of the aforementioned modes (gas borrowing at the firing covette by channels (39, 40), grooves (40 bis), lights or crenels (40 ter) radial ...). on the use of one or more closed patella corollas (41sept, 41 oct, 41 nove), mounted serially on the piston, the opening oriented towards the party, and characterized in that: - the thickness of the section regularly decreasing, according to a preferentially but not exclusively curved generator, between the base (B) and the upper edge (O) so as to favor, under the pressure of the gases or a shrinkage of the chamber (62), a variation combined radial elastic of the curvature with a twist of the complete section (Fig. 6/17) which pivots around the rounded inner edge (Fig. 6/15, B) of its base, - the outer face comprises an angular sector (fig. 6/15), on either side of the point (C) of larger bore, of radius advantageously close to that of the receiving chamber in order to promote a bead sealing contact peripherally of the patellar type7 - the outer face may comprise a crown (41 ten) whose opening is of opposite direction to that of the corolla (41 nove) and such that the equation at rest of its point (D) of greater diameter is greater than that of the flechette (C) of said corolla and that of a shrinkage of the chamber (62) for receiving the plunger, - the inner edge (Fig. 6 / 1S, B) of the base of the section is preferably circular in order to ensure a cross-sectional sealing of the section by valve action between the walls (FIGS. 6/16 & 6/18, 42 quint & 42 six) of its groove (42),

  - The extension, at rest, of the upper outer edge (Fig. 6/17, point 0) is at most equal to that of the piston.

  Each corolla (Fig. 6/16 & 6/18) is mounted with a certain lateral and longitudinal clearance in a housing housing (42) of the piston having at its lower edge a groove (42 quarter) of reception of the base or foot of the corolla to facilitate the angular displacement of torsion of the section and the patellar contact of the inner edge (FIG 6 / 1S) rounded of said base with the lower shoulder (42 srx) of the groove ( 42 quarter) or his upper shoulder

conical (42 quint).

  The corolla (Fig. 6/16, 41 sept) has the advantage of sealing during expansion as a radial contraction. This property makes it possible to play on the relative tolerances of machining piston / chamber / corolla so that the neck (FIG 6/15, C) of the corolla is advantageously in contact with the wall of the chamber when the piston is at the end of race of its sealing housing (62). For this purpose, the bottom of the hinge (62) is characterized in that it comprises a conical shrink (FIG 6/16, point A.), rectilinear or rounded such that the piston / chamber machining tolerance rating is equal to or less than that of the mammalian bead (Fig. 6/15, point C) of the corolla

  when the piston is racing.

  This arrangement ensures a contact (FIG 6/16) of the corolla with the wall of the chamber (62) of the full closure of the cylinder head, eliminating any risk of leakage may result from an expansion time of said corolla during of the

increased gas pressure.

  In order to avoid any risk of introducing dust, grains of sand or other impurities which may scratch the chamber of the pisto4 a corolla (Fig. 6/16, 41 oct) can advantageously be mounted head-to-head with the corolla seal (41 Sept) so as to constitute a scraper corolla such that the generator at its convexite arrow is in contact with the edge of the room entrance as the cylinder head is fully closed. The position of this corolla on the piston then acts as a plug sealing the ltentree of the chamber (62). In order to avoid any effect of scraping on the body of ammunition, those skilled in the art will however ensure that the boring at the outer upper edge (fig.6 / 15, point 0) of this corolla (41). oct) is not greater than that of the piston,

  This does not preclude that the maximum height at the level of the fleche is (1/100 mm).

  In the case of the use of corollas (Fig. 6/18, 41 nove) comprising a crown (41 ten), the oversized bore of the latter relative to that of a shrink (rectilinear conical ...) (fig. 6/18, pt A) of all or part of the length of the chamber (62) provides two functions: an initial torsion of the section during progressive engagement with said shrinkage (Fig. 6/18 'pt A) by the crown (41 ten) leading to an increase in the extension of the neck of the corolla (41 nove) to

  possible contact with the wall of the chamber (62) ,.

  an increase in the tightness by simultaneous contact, during the rise in pressure of the gases, the generators of contact of the corolla (C) and its crown (D) with the wall of the chamber (62),

  - a scraper effect of the crown (41 ten) during recur of the piston.

  Figure 6/18 shows two corollas (41 nove) with crowns mounted one behind the other and separated by a washer (42 oct), the head corona undergoing, in contact with its crown (41 ten) with the shrinkage (Fig. 6/18, point A) chamber (62), a twist to open and press his neck against the wall of the chamber promoting immediate sealing. The second corolla not yet engaged the chamber entrance neck is in the rest position. A progressive shrinkage of the boring located at the bottom of the chamber can not trigger the mechanical opening of the head corolla when the piston is at the end of the race. Appropriate dimensioning of the second corolla and in particular the boring of its crown so that it is in contact with the chamber entrance.

  that the breech is fully closed will assure him the role of stopper.

  The washer (42 oct) separating two horns mounted serially advantageously has on its periphery grooves (40 bis) for supplying the lower corolla gas in case of rupture of the first. The lower edge (42 six) of the housings (42) corolla comprises a shoulder (FIG 6/18, 42 nove) conical favoring the movement of the crown (41 ten). The assembly of the corollas is possible by the realization in several parts (or stages) of the piston as indicated in Figures 6/16 and 6/18, the upper part or head ensuring the double role of

  1 0 busc protecting the corollas and segments and pusher cartridges during their introduction into the chamber.

  In order to overcome any adjustment deviation of the piston pin with that of the chamber, the corollas wind up with a certain vertical and lateral clearance (FIG 6/16) favoring their perfect centering of the contact with the wall of the chamber. bedroom. The lateral play of mounting of the corollas (41 nove) with crowns (41 ten) is at least equal to the difference of boring of these derrieres with the piston (causing ['erasure of their contact zone with the ammunition during the movement of the

  1 5 yoke) to avoid any risk of scraping said crowns on the ammunition bodies.

  Any offset of the piston is automatically compensated by the patellar machining of the convex wall of the crowns.

  ensuring the perfect contact of a generator with the wall of the room.

  The nature of the invention would not be changed if the profile or generator of the section of the corolla was different, by

  example rectilinear or if it had two branches or secants other.

  Integral patella corolla piston 8/28, fig. ff / 19 & plate 9 / 28fig. d / 20): A simplified realization of the principle of sealing by patellar crown can be obtained by integrating the base of the corolla (41 eleven) to the lower part (17) of the piston or mandrel located behind the head (40 quarter) comprising the firing bowl and the crenels (40 ter) of gas supply. The patellar spindle can then easily be produced by machining the corolla in the mass of the material constituting said piston with the characteristics relating to the elasticity of the only profile of its section: the thickness of said cross-section regularly, according to a generator preferably but not exclusively curved so as to favor, under the pressure of the gases or a shrinkage of the chamber (62), a radial elastic variation, the external face comprises an angular sector (Fig. 6/19 ), on either side of the point (C) of larger bore, of radius advantageously close to that of the receiving chamber to promote a sealing contact boring circumferential type of patellar,

  - The extension, at rest, of the upper outer edge (Fig. 6/15, point 0) is at most equal to that of the piston.

  Any axial offset of the integrated patella corolla piston is automatically compensated by the patella part of the

  external wall of the crown ensuring a perfect contact of a generator with the wall of the chamber.

  The corolla of the piston (41 eleven) may also include a crown (41 ten) in the same manner as that previously exposed. Operating principle: At the start of the stroke, the propellant gases take the channels (39, 403, flutes (40 bis), lights or crenels (40 ter)) out of the firing bowl of the piston head (40 quarter) and operate immediately. a uniformly distributed pressure (symmetry of said channels, crenels and lights) on the inner wall of the corolla (41 sept, oct, nove & eleven) producing a variation of its curvature combined with the torsion of its section (41 sept, oct & nove ) leading to its uniform expansion and its contact with the wall of the chamber (62) for a perfect tightness resulting from a double action: - facing the peripheral gases of the piston which wind blocked by the contact (Fig. 6/16) a generator (Fig. 6/15, C) of the patellar boring zone (and, where appropriate, a contact generator of the crown 41 ten) with the wall of the chamber; gas circulating at the back of the corolla (41 sept, oct & nove), blocked by the clapper effect of the contact patellar of the circular section of the inner edge (Fig. 6 / 1S, B) of the base of said corolla playing between the lower shoulder (42 six) of the throat (42 quarter) and its upper shoulder conical (42 quint) depending on the pressure of the gas pushes the corolla towards the teas piston or that friction against the chamber tend to raise it. As soon as the good fate of the barrel the pressure drops instantaneously, the elasticity of the corolla causes its return to the nominal diameter eliminating any risk of blocking of the piston to the entrance of the home cock (62) during the next movement before the breech. In the case of use of a crown corolla the return to the diameter

  The nominal value of the collar is only after the opening of the cracking of the chamber by the piston.

  Note: during the firing of the ammunition, the recur of the hiphole piston favors the deposit of the fatty residue of combustion of the thruster on the walls of the chamber which is thus self-lubricated This lubrication will facilitate

  ['introduction of the piston and increase the life of the segment.

  Those skilled in the art will adapt the dimensions, materials and thicknesses of the corolla to the pressures involved (several milkers of bars) in order to advantageously combine the intrinsic torsional elasticity of the section as a variation of its curvature. It will also adapt the number of corollas to be mounted in series, one behind the other at the head.

  1 5 piston so, if necessary, provide greater security in case of accidental breakage of the party.

  In order to guarantee a long longevity of the corollas and pistolls with integrated patella corolla (41 eleven), these will be realized in an elastic material (UE9P bronze, steel, cast iron ...) able to withstand the efforts of temperature and friction. A self-lubricating treatment (titanium nitride, Diamond Like Carbon, amorphous carbon, molybdenum, graphite, etc.) can also be applied. In order to increase the intrinsic elasticity of the corolla a stabilization annealing may be applied in order to set the maximum equilibrium at rest to a value lower than that obtained a

after machining.

  The radial elasticity of the corolla also plays the role of wear compensator to guarantee a contact always

  perfect of the convex part with the wall of the chamber, in expansion as in compression.

  Note: The corolla (41 sept, nove & eleven) can naturally be adopted in all modes of operation (a

  to seven) described in this patent.

  Application: high pressure and temperature control cylinders. Combustion engine. This type of corolla can naturally find application in the engine two or four times in singing place as described, even immediately at the head of piston, in particular according to the simplified formulation (plate 8/28, fig 6/19 & plate 9/28 fig 6/20) or it can then be directly factory in the piston head. The bore will be adapted to be in permanent contact with the wall of the chamber. The dimensions and in particular the thickness and the curvature will be adapted to the lower compression pressure of the engines. The introduction of the piston into the chamber for the

  mounting will naturally steffectuera through the top of chamber in order to contract the segment / corolla.

  Having no aperture, such a segment should substantially increase the compression efficiency by

  producing an additional hiphite effect at the gas pressure.

  Fifth mode (Plate 9/28, Fig. 7/3 & 7/4): In a fifth embodiment of the ehancheite, the piston (Fig. 7/3) of the chuck having a groove (42) housing home of a segment or couple of sealing segments is characterized in that it consists of a sleeve (44) central whose front face corresponds to the bottom of the firing bowl, pumps (or bars) with a spring (47) positioned in a star around the central axis, an axial ejector / igniter (27) and a munition extractor (22) articulated at the sleeve and provided with a foot cooperating with the valve head

of the ejector / igniter.

  The segment or couple of sealing segments (41) (41, 41 bis, ter, quarter & quint, seven) is characterized in that its outer diameter at rest is such that it retracts inside its throat welcome and do not go past

The size or diameter of the piston.

  The central sleeve, consisting of two parts promoting the mounting of the segment and secured by a pin, comprises two bearings (45 & 45 bis) tapered, the first simultaneously providing gas tightness and the role of race stop said sleeve and the second (45a) conical ensuring more particularly the role of compression slide of the spring pumps. The pump springs (47) are arranged in a star-shaped fashion around the sleeve housing (44) with which they communicate and open on the other side in the housing of the segment (42a). The festival pumps press against the inner face of the segment (a groove can advantageously be arranged), their feet resting simultaneously on the cylindrical portion of the bearing (45 bis) conical slide sleeve. These pumps, once in place, also provide the function of displacement stop (anti-extraction) of the

central sleeve.

  A variant (FIG. 7/5) of the preceding assembly can be obtained by replacing the spring pumps with balls or tenons all around the sleeve (44) in the groove, specially designed for this purpose, for housing the segment (41). ) and mounted so as to be simultaneously in contact with a conical bearing (45a) of the sleeve and the inner face

audit segment (41).

  The sleeve may, in addition, advantageously comprise a second conical bearing (45 ter) on which are rested bolts or tenons of solidarization breech / gun appaires and star-mounted in conical housings preventing any output of said balls or tenons, said housing being next to matching female dwellings (56b)

  arranged in the chamber of the sealing piston.

  The distance between the bottom of the firing bowl and the ammunition chamber head may be adapted so that the depression of the sleeve head (45) occurs at the end of the forward movement of the bolt, said head abutting against the bottom of its receiving housing under the action of the recuperator spring (110). The sealing segment (and possibly the bolts or tenons for joining breech / barrel) is / are then systematically discarded) when

the breech is closed.

  The adoption of a shorter mandrel, eliminating any butee of the head against the bottom of its housing, will cause a gas pressure operation. Those skilled in the art will be careful to adjust the bore of the chamber (62) with the

  optimal expansion dimension of the segment (41) for the best sealing.

  Principle of operation: When firing the ammunition (Fig. 7/3) the propellant gases exert a pressure equivalent to the rear of the ammunition and on the head of the sleeve / bowl of firing which sinks inside the chuck / piston by contracting the

return spring (44 ter).

  The conical bearing (45a) of the sleeve abuts on the symmetrical conical bearing of the mandrel (17) ensuring the internal sealing of the mandrel, as well as the conical shoulder (45) on the symmetrical conical shoulder of the mandrel (17), and simultaneously exerts a radial pressure on the spring pumps which compress and cause a uniform increase in the diameter of the sealing ring by pressing against the wall of the cylinder (62)

  piston housing thus ensuring gas tightness.

  Simultaneously, the piston moves back (except for the presence of a mechanical locking system for the cylinder head / barrel) ensuring the delay in the opening of the chamber, the sleeve / firing bowl remaining in force in the mandrel until the pressure of the gases is reached. cancels (opening of the room). From the recording of this pressure drop, the sleeve / firing bowl returns to its initial position under the effect of the return spring (44 ter). The pumps resume their initial length under the combined action of the segment contraction pressure and the return to the conical bearing rest position.

  (45a) of the sleeve causing an elongation of the stroke of said pumps.

  The segment then retracts into its housing towards its rest position so as not to exceed the bore of the piston and not to compromise the next introduction to said piston in its reception chamber (62). The electric igniter (27) provides a quadruple function: sealing, cartridge ignition, ejector and return spring of the extractor. For this purpose, the latter (22) has a foot resting on the conical portion in the form of a valve of

  The ignition thus benefiting from the latter's spring for its own recall function.

  When the central sleeve is pushed in, the spring pumps ensure a quasi-constant pressure of the segment

  on the cylinder, without risk of tightening or blocking.

  In order to ensure a radial distribution of optimum pressure, their number (greater than four) will be adapted by those skilled in the art and their length will be such that when the sleeve is in force and the segment plate against the wall

  of the cylinder, the said pumps do not work, but at the end of a contraction.

  In order to guarantee a long longevity to the segments, these will be realized in an elastic material (UE9P bronze, steel, cast iron ...) able to resist the efforts of temperature. The friction of the segment on the wall of the cylinder can be reduced by the adoption of a slightly convex outer surface (some 1/100 of a millimeter) and the application of self-lubricating treatment (titanium nitride, Diamond Like Carbo4 amorphous carbon , molybdenum,

graphite.) idoine.

  This device, in the case of use of a non-stalled cylinder head, is a real regulating system of delay at the opening of chamber controlled by gas pressure. The advantage of this formula and allow the weapon to "digereryy a large variety of ammunition of different masses, without the need to change the barrel or the mass of the breech, taking care however to verify that the length of recur of the sealing piston in its

  chamber is sufficient for the type of ammunition considered.

  In the ball variant (FIG 7/5) the depression of the sleeve (44) produced, in the case of adoption of the breech / barrel securing device, a double effect: the expansion of the sealing segment and said Mechanical fastening breech / barrel. During the firing of the ammunition the propellant gases exert a pressure equivalent to the rear of the ammunition and on the head of the sleeve / firing bowl which sinks inside the mandrel / piston by contracting the spring of recall (44 ter). The conical bearing (45) of the sleeve (44) abuts on the symmetrical conical bearing of the mandrel (17) ensuring the internal tightness, simultaneously the tapered shoulders (45a and 45b) exert a radial pressure on the balls or tenons with which they are in contact and cause: - the uniform increase of the diameter of the sealing segment which marries the wall of the cylinder (62) of reception of piston thus ensuring the perfect sealing to the gases, 1 5 - the joining breech / barrel by displacement of the balls (54) or tenons in the dwellings (56 ter)

  home fit seal piston.

  It should be noted that the segment ball expansion mechanism and the cylinder head / cannon wind splitting mechanism are dissociable and can be mounted separately or combined with others. Similarly, those skilled in the art will appreciate

  the opportunity to substitute the balls with spring pumps for sealing.

  Sixth Mode (Plate 9/28, Fig. 7/1 & 7/2): In a sixth embodiment of sealing, the piston of the chuck having a groove housing (42) for receiving a segment or couple of sealing segments, is characterized in that it consists of a sleeve (44) central two parts whose front face of 1'une one (44 bis) comprises the bowl of shooting, an expansible washer in star shape (Fig.7 / 2, 46) seated on an ad hoc bearing (45 quarter) of the central sleeve, an electric ejector / igniter (27) and a munition extractor (22) articulated at the sleeve and provided with a

  foot cooperating with the ejector / igniter valve head.

  The segment or couple of sealing segments (41, 41bis, ter, quarter & quint, seven) is characterized in that its outer diameter at rest is such that it remains retracted inside its throat and does not does not exceed the bore or diameter of the piston. The expansible washer (46) is conical and its action, once engaged on a bearing of suitable diameter, is such that an effort tending to its flattening results in a perfect radial increase of

  its diameter. Those skilled in the art will be able to adapt the number of washers as much as the configuration of the segments.

  The central sleeve comprises a first bearing (45 quarter) washer seat (s) expansible (s) and a second bearing (45) conical simultaneously ensuring gas tightness and the role of race stop said sleeve. The length of the mandrel may be adapted so that the recess of the piston head (44 bis) occurs at the end of the forward movement of the bolt, said head abutting against the bottom of its receiving seat under the action spring

  recuperateur (1101. The sealing segment is then systematically dilate when the breech is closed.

  The adoption of a shorter mandrel, removing any butee of the head against the bottom of his housing, drives a

operation at gas pressure.

  The electric igniter (27) provides a quadruple function: sealing, cartridge ignition, ejector and return spring of the extractor. For this purpose, the latter (22) comprises a foot mounted in abutment on the conical portion in the form of a valve of the igniter / ejector (27) so that the return spring to said igniter also ensures the function of

recall of the extractor.

  Principle of Operation: When firing the ammunition the propellant gases exert a pressure equivalent to the rear of the ammunition and on the head of the sleeve which sinks into the mandrel by compressing the expansive washer (46) which addicted t his

  diamitre and then exerts a radial pressure on the segment (41).

  The latter is plate against the wall of the cylinder (62) for receiving piston thus ensuring perfect sealing gas.

  Simultaneously, the piston moves backwards (unless there is a delay system at the opening by joining the cylinder head / barrel), the head of the sleeve remaining depressed until the gas pressure vanishes (opening of the chamber). When recording this pressure drop, the piston head returns to its original position under the combined effect of the spring.

  booster (44b) and expander washer.

  The segment then retracts into its housing towards its rest position in order not to exceed the boring of the

  piston and not to compromise the next introduction to said piston in its room of reception (62).

  In order to avoid any risk of clamping the segment against the wall of the reception chamber under the effect of a compression too fast and important expansible washer, the return spring (44 ter) can advantageously be coupled with ( or replace by) a stack of spring washers of type "Belleville" whose crushing

  1 0 progressivepresidera that of the expansive washer.

  In the same spirit, the washer may be designed in a material or in such a way that its force is limited by a buckling of the radial elements which constitute it to ensure a constant maximum value of pressure of the segment against the chamber. Those skilled in the art will be careful to adjust the bore of the chamber (62) with the

  optimal expansion dimension of the segment (41) for the best sealing.

  In order to guarantee a long longevity to the segments, these will be made of an elastic material (bronze IJE9P, steel, cast iron ...) able to withstand the temperature efforts. The friction of the segment on the wall of the cylinder can be reduced by the adoption of a slightly convex outer surface (some 1/1000 of a millimeter) and the application of self-lubricating treatment (titanium nitride, Diamond Like Carbon, carbon amorphous, molybdenum,

graphite ...) idoine.

  This device, in the case of use of a non-stalled cylinder head, constitutes a real regulating system of delay

  The chamber opening controlled by gas pressure.

  The advantage of this formula and to allow the weapon to "digeren" a large variety of ammunition of different masses, without requiring modification of the barrel or the mass of the breech, taking care however to verify that the length recur of the sealing piston in his room is sufficient for the type of ammunition

considered.

  Seventh mode (Plate 9/28, Fig. 7/6): In a seventh embodiment of sealing, the piston of the chuck (17) has a groove housing (42) for receiving a segment ( 41 six) annular and expandable, a sleeve (44) central whose front face comprises the firing bowl, an ejector / igniter (27) and a electric extractor (22) ammunition articulates at the level

  the sleeve and provided with a foot cooperating with the valve head of the ejector / igniter.

  The sealing segment (41 six) is a closed metal ring with known elasticity, of section having a trapezoidal shape / isocele triangle whose tip is turned inwards and characterized in that its outer diameter at rest as long as it remains retracted inside its groove and does not exceed the bore or diameter of the

piston.

  The isoceles dimensions of the wind segment resting on surfaces symmetrically arranged on the head (44 bis) of the sleeve and the mandrel (17) at the groove (42) housing of the segment, it is possible to produce an expansion of the segment when a compressive force is applied to said piston head. The central sleeve (44) comprises a conical bearing (45) and a shoulder at the height of half of the groove (42) accommodating the segment (41 six) acting as a stop for the said sleeve in order to prevent any crushing or jamming of the ring (41 six) against its supports. The electric igniter (27) provides a quad function: sealing, cartridge ignition, ejector and

return spring of the extractor.

  For this purpose, the latter (22) comprises a foot mounted in abutment on the conical portion in the form of a valve of the igniter / ejector (27) abn that the return spring to said igniter also ensures the return function of

I'extracteur.

  Operating principle: When firing the ammunition the propellant gases exert a pressure equivalent to the rear of the ammunition and on the piston head which causes the expansion of the segment (41 six), absorb in passing a part recur

  The weapon, via the pressure exerted by the mandrel / piston crown on the isosceles faces internal to said segment.

  The latter is then plate against the wall of the cylinder (62) for receiving the piston, thus ensuring a tightness parite to the peripheral gases of the piston head traps between the contact surfaces of the segment with the sleeve (44) and the

bedroom (62).

  Simultaneously, the piston moves back (unless there is a delay system at the opening by cylinder / gun connection), the head of the sleeve remaining depressed until the pressure of the gases is depressed. From the recording of this pressure drop the piston head resumes its initial place under the combined effect of the return spring (44 ter) and

  the elasticity of restitution of the segment.

  The latter then retracts into its housing towards its rest position so as not to exceed the bore of the

  piston and not to compromise the next introduction to said piston in its room of reception (62).

  In order to avoid, especially in the case of a non-wedged cylinder head, any risk of clamping the segment against the wall of the reception chamber under the effect of its expansion force, the return spring (44 ter) can advantageously be coupled with (or replaced by) a stack of conical springs Belleville type springs whose progressive crushing presidera expansion segment. Those skilled in the art will ensure the adjustment of the bore of the chamber

  (62) with the optimal expansion dimension of the segment (41 six) for the best waterproofness.

  In order to guarantee a long longevity to the segment, it will be made of an elastic material (steel, cast iron ...) able to withstand the efforts of temperature. A self-lubricating heat treatment (titanium nitride, Diamond Like Carbon, carbon graphite, graphite, etc.) can also be applied, especially on the isosceles faces of

  contact of the segment with the sleeve and the mandrel.

  This device, in the case of use of a non-stalled cylinder head, constitutes a real regulating system of delay

  chamber opening controlled by gas pressure.

  The advantage of this formula and allow the weapon to "digest" a large variety of ammunition of different masses, without the need to change the barrel or the mass of the breech, taking care however to verify that the recur length of the sealing piston in its chamber is sufficient for the type of ammunition

considered.

  Note: any combination of modes 1 to 7 previously exposed would naturally fall within the scope of

  The invention as well as any formula for producing uniform expansion of segment joints for sealing purposes.

  The aforementioned modes also have the advantage that they can be adapted to any weapon using a breech lock.

  DESCRTION AND ROLE OF THE MANDR OF CULASSE WITH IMPRISON OF GAS (Pianches 2 & 3/28).

  The breech chuck is a cylindrical piece, cooperating with the breech in which it is housed to perform the functions of introduction, ignition and extraction of the ammunition. For reasons of machining and ease of montageldemontage the mandrel is made of two main elements: - a body comprising (FIG 3): - a piston (18) of waterproofness provided with a bowl of reception (or of shot) of the base of the ammunition, - an igniter / ejector assembly (27) following the central axis and opening into the firing bowl, - an articulated extractor (21) provided with a hook opening on the single front face of the piston - an extractor plunger (23), - an extractor plunger spring (24), - an igniter / ejector buffer stop (25), - an electrical insulator (28), - an attachment extension (30) ignition / ejector, - housing (56) posts (54, 55), - channels (40) drilled in the mandrel body in a substantially radial direction opening into the groove (42 bis) circulation gas concentric with the housing of the sealing segment and / or tenons (FIG 6a) and communicating with channels (39) parallel to the central axis and opening into the senle bowl of shooting, - a skirt (fig. 4 & 5) surrounding the mandrel body and comprising: - a receiving housing (42) of a sealing segment (41), - channels or orifices (40) in a radial direction passing through the piston skirt and opening into the concentric gas flow groove (42 bis) at the housing (42) of the segment, located in direct line with the channels (40) arranged in the body, 1 0 - as required: orifices (56) acting as post stops (54, 55), if necessary: movable tenons (54, 55) for securing

  barrel / breech during the journey of the ammunition in the barrel.

  The mandrel housing in the cylinder head is such that the piston (18) is in a good way to penetrate, when closing the culasselcanon, in its receiving housing of the barrel to a depth such that, when setting the ammunition, the recur of the breech and the piston do not lead to the opening of the chamber until the ammunition

cannon

  In order to guarantee a maximum tightness to the chamber during the firing, the afore-the-ejector and the extractor open

  on the only front face of the cylinder head piston.

  Modes of realization of the igniter / ejector:

  The functions of ignition and ejection of a cartridge (for defectuosite or extraction of the hinge) are ensured by one and the same piece: theDumeurjecteur (27) which crosses the mandrel according to its central axis and opens in the middle of This piece has a form of valve at its head and has at its other end a groove for engagement of a clip for securing a hooking extension (30) on which a stop (25) The valve is then retracted and its valve closed in the tin bowl. This valve acts as a contactor to act as an ignition switch / ignition switch to electrically firing the cartridge. Wile is in contact

  permanent with the electrical power source via a spring plunger connection.

  Without changing the nature of the inventio4 the reminder of the valve (Plate 6/26, fig.7) of the tumbler / ejector in position ferrnee can also be provided, instead of the action of the stop (25). ) buffer on the attachment extension (30), by a spring (29) surrounding the attumeur and exerting its pressure simultaneously on the bottom of its housing and

['attachment extension (30).

  The igniter / ejector (27) is covered with a layer (28) of insulation (ceramics by plasma torch ...), rectified by

  machining after deposition, in order to respect the polarity of the voltage of ignition and to prevent any risk of short circuit.

  The nature of the invention would not be changed if the insulation (28) was located in the same dwelling

  the attumeur / ejecteur. The ignition voltage is exerted between the firing bowl and the auger / ejector valve head.

  Ejecting function of the igniter / ejector (plate 2 to 9n8 & 21/28): During the rearward movement of the cutasse ['attachment extension (30) of the attumeur / ejecteur strikes a stop (77) via a extension piece (30) causing the opening of the valve driving the ejection of a cartridge

  which would have been removed by the extractor (21).

  Temperature resistance of the mandrel head / ammunition chamber: In order to ensure optimum temperature resistance of the propellant gases of your ammunition chamber, of the firing basin and of the extractor, a ceramic treatment by Projection under a plasma torch (or other equivalent means) may be applied. This provision also aims to prevent the phenomenon of "cook-off" or self-ammunition ammunition when introduced into the room.The establishment of a ceramic insert (atumine, Zircon ... whose profit corresponds to that The chamber will lead to a fully ceramic chamber interior and will advantageously delay this phenomenon.The head of mandri4 the firing bowl and the extractor may also be the object.

Ceramic reatisation.

  Realization of the chuck body (plate 2 to lOn8):

  The chuck body is factory in order to accueitlir all the elements it contains without the need for screw mounting.

  This construction principle is respected for the whole weapon.

  Thus, the machining in the mandrel body of the receiving housing of the extractor puller assembly (23), spring (24) and abutment (25) 1 'stringer attachment extension (30) The ejector has a semicylindrical opening (FIG 4, N 50) for a length permitting each of the elements to be successively inserted, taking into consideration the extractor, the pusher, the pre-compressed spring and the stop. . Then engage the mandrel body

  in his skirt that will solidify the whole.

  The assembly of the igniter / ejector is carried out by introducing it by the firing bowl, taking the vein of preliminarily lapping the valve-shaped head in its home of the tin bowl once assembled. place, introduce ['extension hooking (30) of the hammer on the rod (27) and then secure the two pieces (27) and (30) a

  using a clip and engage this back on the stop (25) if necessary.

  In order to guarantee the seal at the buffer stop (25) of the hammer hammer, it adopts a conical valve profile (Fig. 6/4, 49) and is held closed by the action of the spring (24). ) of the attachment extension (30)

  igniter / ejector which she shares the thrust with the latter.

  The two-piece mandrel skirt (Fig. 5, N 20 & 20 bis) adopts a perfectly machined cylindro-conical shape (low tolerances) to accommodate the mandrel body and has at its base a conical shrink (51) for to cooperate with the bottom, symmetrically conical, of the logesnent of reception of the slide. This provision is intended to achieve a seal type "valve" ensuring the absence of hot gases that reach the back of the slide. This skirt is in two parts to allow mounting of the sealing segment by threading from the teas of the mandrel without risking to exceed its limit of elasticity. Those skilled in the art can realize in a single block the

pieces 50 and 20 bis if necessary.

  Note: the rear of the breech of the weapon is one-eyed. No orifice is present and no risk of hot gas leakage

There is nothing to fear.

  The body / mandrel / mandrel / slide connection is provided by any suitable means (pin ...). One of these means allowing rapid disassembly can be based on the principle of overtaking the head of a diver a

  spring, housed in a blind hole of the mandrel, debouching in a specific orifice of the slide.

  It then suffices, to separate the rnandrin of the slide, to press on the head of the diver and hold it down

  to allow the chuck to slide freely out of the slide.

  D DELAY IN OPENING BY EMPRUNTDEGAZ (PLANNE10 / =, nG 7n & 7 A vesrouillage of ['set barrel / slide can, on a weapon according to the invention, be introduced to obtain an additional delay at the opening This provision has an interest in weapons whose power of

  ammunition could lead to a too rapid opening of the chamber and a prohibitive length of the piston.

  The principle of gas borrowing at the level of the firing basin, as described above, can be used here

  to create a delay in opening additional to that provided by the recur of the piston.

  For this purpose, in a first embodiment, the mandrel piston comprises radially arranged stud housings (FIG 7/8), communicating with channels opening into the firing bowl, which ensure the displacement of tenons (54). that they contain in a radial direction towards the outside of the skirt, said skirt comprising a

  conical docking orifice limiting the stroke of each stud and operating a valve-type waterproof connection.

  The reception chamber of the mandrel piston is characterized in that it comprises female housings (56 bis) for receiving the tenons present on the piston and against which they are directly located. These tenons, in variable number, adopt, preferentially but not limitatively, a sphere shape (54) or present a base

  flattened (55) surmounted by a cone ends with a last-sphere.

  From the firing of the ammunition, the pressure of the propellant gases acts on the base of the tenon (s) which immediately come to be positioned in their respective housings (56 bis) of the chamber of reception of the piston, blocking

thus the opening barrel / slide.

  The pressure drop recorded from the barrel ammunition outlet has the effect of canceling the pressure on the base

  tenons that release the connection barrel / slide then promoting the opening of the room.

  The tenons wind mad in their home, their return to the erased position taking place naturally under

  the effect of the barrel / slide separation.

  In a second embodiment (FIG 7/7) the housings (56) of wind tenons arranged radially in the

  barrel wall at the ammunition chamber in which they open directly.

  The pressure of the propellant gases ensures the displacement of the tenons they contain in a radial direction and outwards in order to cooperate with a housing (56 ter) female corresponding factory in the slide of fac

  ensure a link barrel / rigid breech at the start of the blow.

  The pressure drop recorded from the barrel ammunition outlet has the effect of canceling the pressure on the base

  tenons that release the connection barrel / slide then promoting the opening of the room.

  The slide is characterized in that it comprises housing (56 ter) females host tenons present on the barrel and against which they are directly located. These tenons, in variable number, adopt, preferentially but not exclusively, a sphere shape (54) or present a base (55) flattened overcomes

  of a cone ends with a half sphere.

  Note: the nature of the invention would not be changed if the tenons, according to any of the assemblages previously mentioned, were articulated in any way whatsoever (axis depone ...) or provided with any means whatsoever of

reminder (spring ...).

  This temporary securing device barrel / slide is particularly advantageous in that it ensures a self-regulation of the delay at the opening which is directly proportional to the pressure variation in the chamber,

  So the precise moment of the exit of the beautiful cannon.

  This system presents, correlatively, the advantage of an automatic adaptation of the weapon to cartridges.

  different powers or masses involve, for the same caliber, modifications of parts.

  SHORT MECHANISM RECEIVED FROM CANON (Plate 11/28, Fig. 8 & 9).

  A mechanism allowing a short recur of the gun, based on a principle of sliding said gun in a

  cradle (107), can easily be established, without increasing the complexity or congestion of the weapon.

  The barrel (60) is slidably mounted, over a length of a few millimeters, in its cradle (107) integral with the

  carcass and held in position under [action of a damping spring (110).

  This cradle consists of a hollow cylinder, of an inner diameter to accommodate the barrel, and comprises

  a plurality of guide grooves (108) cooperating with corresponding rails (109) of the barrel.

  Two of these rails are located horizontally along the barrel and 180 from each other, a third is. if necessary, position vertically along the axis and the teas of the barrel. The two horizontal rails (109) are advantageously aligned and of the same format (height and width) as tenons (112) integral with the barrel and placed further forward. The barrel is introduced, mouth first, until the shoulder of the piston chamber abuts on the front face of the cradle. The damping spring (110) is then introduced, muzzle side of the barrel, until abutting on the other face of the

  cradle, then slightly compressed so as to favor the mounting of a ring (111).

  This ring (FIG 9) cooperates with the tenons (112) integral with the barrel so as to achieve a bayonet type assembly. The ring (110) is then held in place by the action of the damping spring (110) which allows,

  Simultaneously, a short recur of the cannon.

  This ring acts as a race stop of the barrel and can advantageously be connected to the recuperator spring (57)

  of which it constitutes an ideal seat, facilitating the operations of mountageldemontage of the weapon.

  Note: this system promotes a rapid change of the barrel and therefore the caliber of the weapon by simple adaptation of the

breech and charger.

  Operation of the recur of the barrel.

  From the firing of the ammunition, the pressure of the gases propels the tenons (55) into their housing (56 bis or

  56 ter) of the barrel leading to the barrel / slide connection.

  The assembly then backs up, compressing the only damping spring (110) until the ring (111) abuts on the cradle. The brutal pressure drop following the exit of the beautiful, the tenons release the slide which

  continues its rear movement by compressing the recuperator spring (110 bis).

  Like all automatic weapons, the ammunition supply of the next weapon is carried out by a magazine (9S) whose lips present a cartridge at the entrance to the barrel chamber. The piston of the breech ensures this introduction during the forward movement of the slide by pressing on the rear face of the ammunition and pushing it into the chamber of the piston which plays the role of a funnel improving substantially the quality of 1 cartridges, thus guaranteeing greater reliability than

ammunition has hit.

  During this introduction phase the claw of the extractor (21) engages the groove of the base of the munition to keep it positioned at the bottom of the bowl of tin. The cartridge (1) is then pushed into the shaft until the

closing of the breech.

  Shortly before the end of the race of the ammunition in the chamber, the extractor claw (21) engages, if necessary, the ramp (S 9) home and lifting arranged for this purpose in the barrel. The ammunition is then immobilized in the chamber of the barrel and its rear face is fully supported on the covette firing of the piston under the

  pressure of the recuperator spring (57) closing the slide.

  The lifting of the extractor is justified only in the case of the use of ammunition (pl 1/28, fig 1/2), the cap of which is prolonged in the rear, to protect the thruster. In the case of small caliber ammunition whose extraction throat is an integral part of the solidified propellant, the ignition of the cartridge can be operated engaged extractor, the thruster being transformed instantaneously into gas. A heat treatment of the extractor (titanium nitride), or even its coverage by a projected ceramic will ensure its protection

  DESCRIPTION AND OPERATION OF THE EXECUTIVE SYSTEM OF THE EXTRACTOR uh # n, f1).

  The extractor (21) ensures the removal of a cartridge from the chamber Its resistance allows it to withstand the most violent efforts, especially in case of emergency extraction of a munition for failure to ignite Remember that the design a weapon using ammunition without cases that does not include an extractor would expose the user in the event of ammunition defiOante The extractor adopts a rectilinear form (21) composed of a main arm ends with a bend sensiblernent a right angle a an extremity. The other end has the shape of a hook intended to engage the throat of ammunition. The rectilinear extractor (21) is integral with the breech mandrel by means of a connection using a latch lock (FIG. 3) under the action of a return pusher (23). maintain the extractor in a closed or lowered position and, for this purpose, exercise a

couple on the main arm.

  To ensure when firing, if necessary. the disengagement of the extractor claw of the throat of the ammunition, the weapon according to the invention is equipped with a means of automatic lifting of the extractor at the start of the stroke. For this purpose, the hook of the extractor is terminates with a tip or bevel cooperating with a housing (59) femeOe symmetrically beveled, providing a role ramp (59) for lifting, feeding into the chamber (62) of the barrel This arrangement ensures the automatic lifting of the extractor and its disengagement from the ammunition throat of the

closing the room.

  The length of the main arm of the extractor is adapted to ensure the engagement of the lifting ramp before the cartridge head abuts on the barrel profile entrance. Thus, lifting the extractor hook is

  primer while the ammunition is not fully introduced. During a backward movement, the descent of the hook is initiated

  simultaneously with the recur of the slide while the

* present cartridge is still immobile, to be then immediately engaged by the hook for extraction.

  The purpose of these lifting mechanisms is to release the cartridge before firing and to ensure, by simple manual recoil of the slide, the lowering of the retractor and the removal of a cartridge which would indicate a defect in

  firing for example, to proceed to its immediate ejection of the room.

  The maneuver is absolutely identical to what would be implied by a conventional weapon, involving no effort of

  familiarization or change of reflex.

  OPERATION OF LADETENTE12a14). The detente activates, gradually and sequentially via a helical spring factory in the mass guaranteeing a perfect neutral indexing, contactors at one or more levels to ensure the following functions: - power on, - semi-automatic firing,

- automatic shooting.

  In the case of the use of a single unipolar contactor with two levels, the first corresponds to shot-by-shot and the second to continuous shot. In the case of use of two contactors, each corresponds to a mode of tinning. The shooter can therefore select at will one or the other of the modes of fire on simple enforcement differential of the

relaxation.

SECURUTESDETDR

  The safety of tail relaxation (Boards 11,12 & 13/28).

  At the level of the trigger guard, the stop has a relaxation safety or "contra-detente" (68) characterized in that it is combined with the trigger bolt which consists of a piece comprising two arms of which One is the shape of the trigger guard and constitutes the counter-release lever and the other the trigger guard lock, the head of which also provides the trigger lock function. For this purpose, the arm of the detent tail comprises, close to the axis of rotation, a housing

  (65) Female docking head or pin (66) trigger bolt.

  When it is released from its seat of the detent, the bolt head is supported by action of the latch return spring on the circular cam (67 bis) of the detent arm, thus maintaining the contradiction embedded in its housing (69) of the trigger guard amount. To do this, the cam adopts a circular shape on a corner portion

  correspond to the movement towards the back (shooting) of the tail of relaxation.

  This cam also comprises a recess (67 ter) on a small angular sector so as to cause, during a pressure exerted at the rear of the tail of relaxation, a bossing effect by the slight recur of the pin just before

  the latter does not engage his accommodation home relaxation.

  The detent tail is held in the "neutral" position under the action of two springs (65) and (65a) of return, of equal resistance torques and mounted in a counter-rotational direction. other in order to guarantee an angular displacement of each dimension of a constant neutral position. A single cylindrical spring factory in the mass would ensure the same

  function without changing the nature of the invention.

  Pressing the finger on the rear face of the detent tail will cause the detent to be locked by engaging the head (66a) of the trigger guard latch in the detent receiving housing (67) and the appearance

  simultaneous, in the bridge, the arm (68) contra-relaxation.

  Pressing the front of the index on the detent arm will cause the pin of the trigger guard bolt to disengage from its detent housing, releasing it to its neutral position under the action of his or her return springs. The weapon is then immediately ready at the end This safety presents four advantages: In its principle of use mobilizes the senl finger shooter which, when it acts on contra-detente can not exert simultaneous action parasite on the relaxation and cause an unwanted departure as it occurs on weapons with levers of safety manipulated by another finger than that of relaxation. At its inception is totally ambidextrous and is carried out quickly with one hand, guaranteeing

  a user hurts a hand to be able to free himself from a perilous situation.

  In principle, it is a mistake to co-ordinate, especially in the event of stress, since it requires only one and the same finger to actuate security and security. It is the only way to remain permanently engaged. and be released a

  fraction of a second before a reflex shot.

  Accidental departures are therefore impossible.

  Note: the trigger guard latch allows tilting of the trigger guard around a common axis with the magazine stopper.

  The trigger guard comprises a stop (78) lirnitant the stroke of the slide during the backward movement. The erasure, tilting of the trigger guard, this stop allows the complete recur of the slide which can then beengenged from its guide rails of the carcass to proceed to disassembly of 1'arrne. When opening the trigger guard, the lock is maneuvered by pulling towards the mouth of the barrel, the contra-detente arm which is linked to it then moves to the bottom of the barrel.

  its house (69), provided for this purpose, the amount of trigger guard.

LOAD INDICATOR.

  The weapon is provided with a cartridge presence indicator. This provision is particularly

  important while rare wind models equipped with this indispensable witness.

  To this end, the pit uses the measurement of a very low voltage between the two ignition blades formed by the touchau and the firing bowl, testifying to the presence of a conductor provided by the operculum of the munition. This current can be used to generate a signal on the screen located at the rear of the bolt of the weapon or ignition

  a diode, adjustable light intensity.

  TRANSFER OF INFORMATION BETWEEN CARCASS AND CULASSE (PIANDE 27/28).

  The reciprocating movement of the breech with respect to the carcass entails the need to transfer information and

  electrical energy in a sealed manner between the central computing unit and the detent tail.

  For this purpose, the recuperator spring (57) is characterized in that it is double of one or more conductive threads contained in a sheath (of heat-shrink type) surrounding the wire at the same time. ie the cradle of the barrel and the bolt, so as to ensure a tight multipole connection between the routing wires of the information from the detent (Fig. 29, N 125 quarter) and the calculation block of the bolt (Fig. 29

  N 125 ter). The steel wire constituting the spring ensuring an electric polarity between the yoke and the relaxation block.

  LARGE TANTEM MUNITIONS CONTAINER CHARGER (Boards 15 to 20/28).

  The advantages, uncommon in terms of space reduction (SO%), that allow ammunition without a case, can be used to significantly increase the number of cartridges that can be reasonably housed in a charger. A length of about 20 m / m overall is now possible instead

  29.5 m / m of the 9 mm ammunition, for example.

  This reduction in length makes it possible to naturally position two ranges of ammunition in tandem in the size of a conventional charger without substantially increasing its dimensions. The positioning of two tandem cartridges according to the invention would occupy only a volume of the order of 45 to 50 m / m of length.

  easily integrable in a pistol grip.

  The magazine model (Figures 14 to 18) according to the invention is therefore based on the principle of two compartments tandem (97 & 98), each containing a stack of cartridges arranged in one, two or three piles. These compartments cooperate via common (96) levers for conveying ammunition to the ramp

  gun feed and wind sequentially controlled by a coupling device.

  Each compartment carrier has one or two buttons (101), as required, sliding in a corresponding vertical groove arranged on the side faces of the loader. Thumb action on a button

  ensures the manual descent of the carrier for the introduction of the cartridges.

  The button of the carrier of the front compartment cooperates, when it reaches the end of the race, that is to say when the last cartridge leaves the lips of the charger, with the coupling device compartments for

the power of the weapon.

  Device coupling device (boards 17 to 20/28, Figs 19 to 22).

  The compartments coupling device ensures, during the raising of the cursor or button (101) of the front compartment, the pivoting of a stop (103) which releases the cartridges of the rear compartment. The cartridge of head of this compartment comes then immediately, guided by the levers of the charger, abut against the breech mobile, ready

  for an introduction to the room.

  The main arm of the cartridge stop (103) which has at its end a horizontal stop (103a) intended to prevent, when the magazine is engaged in the weapon, the cartridges of the rear compartment to go up to the level of loader lips to be driven by friction at each passage of the cylinder head, is articulated on the rear wall of the loader well which it is secured via an axis passing through the carcass: - either perpendicular to the axis of the barrel so as to ensure a pivoting towards the rear of the stop which then comprises an arm (103 ter) hooking end at its end with a lug (102) for engaging a hook (102) locking. The stop is recalled in the forward or protruding position (Fig. 20) under action

  a spring (104) located in the receiving recess of its angular displacement.

  It is kept locked in this position under the action of the hook (102) which immobilizes the latching arm. The tilting of the cartridge stopper is controlled by opening said hook

  (Plates 17 to 20/28, Figures 19 to 22, N 102) immobilizing the stopper in the closed position.

  This hook, integral with the wall of the carcass via an axis of rotation, cooperates with ltergot (102 bis) located at the end of the latching arm and further comprises a cam (102 ter) cooperating with the front conveyor button . When the rear cartridge of this compartment leaves the charger's lips, raising the conveyor causes a pressure of the button on the cam causing the pivoting of the hook. The button continues to exert pressure on the latching arm causing it to tilt backwards. The cartridges of the rear compartment are then released. When retracted from the magazine, the pushing of the return spring (104) of the stopper is sufficient to ensure the reengagement of the arm

  hooking by the hook head causing locking of the stopper again in the closed position.

  - parallel to the axis of the front barrel, it is possible to provide a lateral pivoting of the arm (103) of stop and its horizontal stop (103 bis) triggers by the rise of the button (101) forward carrier which, as soon as the rear cartridge leaves the compartment, causes the tilting of a return rod housed in the inner lateral wall of the magazine well and pivotally mounted on its median axis to cooperate with an arm secured to that (103) of the stopper of cartridge to cause it to tilt. The stopper and the return rod each comprise a return spring ensuring their return to the position of the disengagement of the loader. The presence of a stopper hook (102) cooperating with the return rod is not necessary since the thrust exerted by the cartridge on the horizontal stop (103 bis) passes through the central axis of the stop and does not generates no torque justifying a mechanical locking device except,

  possibly, prevention of inertial shock.

  Capacite triple stacking cartridges in the compartments (Fig. 15, 17 & 18) of the magazine.

  In order to substantially increase the firepower of the weapon, a stack of three columns of the cartridges can easily be obtained subject to appropriate sizing and geometry of the cartridge wells of its compartments. Indeed, the rise, under the action of the carriers driven by their respective springs, without jamming the cartridges for the presentation of a single one at the level of the charger lips, requires that the wells have a rectilinear profile of the base up to a certain height and end with a shrink at the top. This shrinkage is characterized in that it is dissymmetric so as to gradually modify, as and when the cartridges rise in the well, their stack of trots a two and a column without the pressure resulting

  exerted on any cartridge by all the others is normal to its bearing surface compartment.

  This dissymmetry is obtained by the application of a particular angle of inclination (or inclination) for

  each side (95 bis & 9S ter) laterally providing the shrinkage of the charger.

  The asymmetry of slope of the loader walls can be easily obtained by making the loader of plastic material (or appropriate resin) not revealing any external dissymmetry or by an adequate enforcement (FIG 18 & 19) of the side wall of each compartment in the case of a metallic realization. SO This arrangement allows to easily accommodate twenty cartridges in each compartment of the charger, carry more than forty shots the firepower of the weapon. An extension charger could easily be worn at twenty-five

  or thirty the number of cartridges per compartment.

Butee antrecul ammunition.

  When rearward movement of the bolt, the anti-recur function of the ammunition of the front compartment is

  automatically ensured by the central partition separating the two compartments.

  Indeed, when the charger is engaged, the head ammunition is pressed a few millimeters by the breech. Its flat face then abuts against the central partition if the fuction caused by the rearward movement of the bolt tends to the

back.

  This function is similarly provided by the cartridge stop and the rear wall height of the magazine well

  for the ammunition of the rear compartment.

  Note: When the front compartment is defective, the upper position of the conveyor, determined by a stop secured to the wall of the loader, may slightly overshoot the top of the central wall to ensure the maintenance of the rear cartridge pressed against them. loader lips, provide a perfect feeding ramp for

cartridges from the rear compartment.

  These are then guided in the tunnel formed by the charger and carrier levers, which they lower slightly during their passage, for an immediate introduction into the chamber under the thrust of the cylinder head piston.

  Device for limiting the capacity of the rear compartment (boards 15 & 16/28, Fig. 14 to 17).

  The following magazine model [invention implies that once engaged in the weapon, only the cartridge of the

  front compartment is in the up position.

  In the case where the design of the loader would not allow, at least one full and front compartment with at least one cartridge, the descent of a sufficient height from the rear stack of ammunition by the cartridge stop

  ['commitment to said charger, a capacity limitation device of this compartment can be set up.

  This device advantageously dispenses users counting a manal number of cartridges to supply in the rear compartment to allow the descent of the stack of ammunition under the action of

I'arrhoir.

  For this purpose, it consists of a lock, automatically erasable during the introduction of the loader into the well of the weapon, limiting the capacity of the compartment to the maximum number of cartridges minus one. This lock prevents the

  carrier of the compartment to go down completely and only allows the entire race once cleared.

  For this purpose, the central wall (98 bis) separating the front and rear compartments comprises, in its plane, a receiving housing of a bar race (106), sliding laterally in said housing so as to let go beyond a

  tongue canted (or rounded) out of the side wall of the loader.

  The central wall also has a rail or slot (98 ter) longitudinal at its center for sliding a lug (100 bis) located on the front of the carrier of the rear compartment. The tongue of the bar is held protruding under the action of a spring (106 bis) and cooperates with the inner wall of the well which ensures its enforcement during the engagement of the charger. The bar preferentially but without limitation

  trapezoidal section to slide in the symmetrical section of the housing housing of the central wall.

  The bar has a slot (106 ter) for 1'embot (100 bis) of the carrier of the rear compartment. The slot is positioned in such a way that it can only be engaged by the pin when the bar that supports it is depressed, that is to say when the charger is engaged in the putts. This device prohibits the feeding of the charger beyond a certain number of cartridges for, enforcement of the protruding part of the stop when

  the complete introduction of the loader obliges, authorize the descent of the carrier.

  This action favors that of the cartridge stopper which causes the descent of the cartridge stack to a height conducive to the passage of the breech head for the exclusive supply of the weapon with the ammunition of the cartridge.

front compartment.

  In order to facilitate the realization of the charger according to the invention, the central wall can be removable and held in position by the reception rails present on the inner walls to said charger. Another embodiment consists of

  use stamped sheet metal pods folded and welded.

  Supply and operation of the loader.

  The supply of cartridges of the following charger ['invention is carried out starting indifferently by

the front or rear compartments.

  The practice shooting, by gusting or limited number of rounds requiring the use of only one

  charger compartment, will be practiced preferentially using the rear compartment.

  Indeed, the latter is the only one whose button lift raises the slider stopper (indifferently mounted on the right or left side of the weapon). The use of the front compartment would result in a closure of the slide on a vice room. The introduction of a raising of the breech stopper by ['ergot of the front compartment, for the preferential use of the latter, is naturally possible but would entail a

  interruption of the complete burst fire sequence of the two compartments.

  The supply of each compartment will be easier than for conventional chargers because of the perfect linearity of surface ammunition. Indeed, conventional ammunition all include a lip at the level of

  crimping case / bullet which causes a scraping effect on the previous case during the introduction of the cartridges.

  The introduction of ammunition in the rear compartment will be further facilitated by the sees, forward tip, of

presentation of the ammunition.

  CLIPPER OF SLIDE lc 21/28, fig. 23).

  For the sake of ambidexterity, the stopper (78 bis) slide consists of a lever whose assembly can indifferemrnent be carried out on one side or the other of the weapon, or be present simultaneously of both quotes to help

  a second lever, at the user's discretion.

  In the case of a simultaneous assembly of the two stops they wind solidarity via an axis passing through the carcass. The levers wind indifferently actuated upwards by the button (101) corresponding to the rear lifting board of the charger present on both sides of the charger. Recall that it is possible to operate also the stopper by the button of the conveyor before the opening of the hook (102) locking the stopper (103) of cartridges. This arrangement allows the indifferent use of the front and rear compartments, but causes, however, a blocking of the cylinder head in the rear position during an uninterrupted firing sequence consuming cartridges of the front and rear compartment. A manual recur of the bolt will allow to resume the shooting sequence in

  introducing the first cartridge of the rear compartment.

  A stop action engagement notch is provided on each side of the slider. However, in the case of simultaneous assembly of two stoppers, only one has a hooking pin: this provision ensures the release

  systematically of the slide, under the action of the recuperator spring, during a pressure on any of the levers.

FUNCTIONING IN AUTOMATIC

  The foregoing description relates to the serniautomatic operation of the weapon, that is to say that each shot of

  ammunition must result from the complete and continuous pressure of the shooter on the tail of relaxation. Operating

  automatically, the weapon must be able to continue to fire until the detent tail is released.

  For this purpose, ignition voltages are delivered to the ignition of the ammunition firing at a rate triggered by the clock with a flexible rate. To do this, the weapon is connectable at any time, via its special port, to a computer to enter into memory of the central computer shooting parameters, including the burst rate and the limiter of shots for selective shooting since the shot by blow, gust of two or

more until the unlimited gust.

  COMPENSATION FOR THE SURVEY OF THE WEAPON (Boards 108 & 12/28, Fig. 7 & 10).

  The recurition compensation at the recur of the weapon in automatic shooting of ammunition in burst (or blow by blow) is carried out by sampling gases at the ammunition chamber, said gases being evacuated at the end of the

  barrel in a substantially vertical direction and upward.

  The principle of the use of ammunition without case allows a sampling of the gases at the level of the same room then

  that the presence of cases on conventional ammunition rendered it simply impossible.

  The device consists of a vertical sampling channel (90), pierced through the upper wall of the barrel at the entrance of the ammunition chamber, communicating: either with a tube mounted and parallel to said barrel and opening towards the high at its end (the breech

  is arranged accordingly and has a female housing for receiving this tube).

  or with a channel (FIG 10, n 92) pierces longitudinally in the thickness of the slide along the axis of the barrel and debouching at its end in a substantially vertical direction and upwards. The supply port of the slide channel adopts a groove shape (91) made on the inner face of the

  slide of a length conducive to promote the supply of gas during the rearward path of the cylinder head.

  This arrangement makes it possible to feed propellant the ramp thus created in the slide and since

  the firing until the opening of the breech.

  When a munition is fired, part of the propulsion gas escapes through the chamber orifice and travels along the slideway via the ramp or the sampling tube to discharge vertically to the end of the chamber. armed. These gases produce a vertical push, instantaneous and in symmetrical progression of the propulsion force of the munition, coming to stop the gradual raising of the weapon consecutive recur produced by the departure of said munition. A good dosage of orifice size and gas progression ramp should ensure a perfect

  Stability of the weapon during firing.

  This compensation formula is the answer which guarantees a perfect synchronization of the anti-raising action.

  with the departure of the beautiful to counter the best recur.

  KEY LAMINATION OF THE WEAPON (Plates 21 & 22/28, Fig. 23 & 24).

  The weapon includes, in order to guarantee use by its sole holder, a device (Fig. 23 & 24) with a key to total prohibition of firing, magazine movement and disassembly of the weapon. This device consists of a lock (114) removable, reduced dimensions and made of metal cur, which takes place in a housing

  host (113) located on the underside of the carcass at the front of the trigger guard.

  This lock passes through the carcass of the weapon to open under the barrel and play the following quadruple role: - stop limiting the race of the breech at the only distance between the lock head and the lower edge before said breech akin to prevent any introduction or extraction of a cartridge, - locking of contra-expansion, displacement of the loader shaft locking rod,

  - lock disassembly lock (trigger guard).

  The setting of this lock is possible only when the safety of detent tail is engaged, causing the appearance of the contra-detente and the simultaneous displacement of the corresponding lock. This recur of the lock releases the opening of the housing (113) for receiving the lock and the pin (115 bis) located at the end of the rod.

  (I 15) for locking the magazine well which opens into said housing.

  This rod, held in position by its return spring, passes through the cradle of the barrel in such a way that its other end opens into the magazine well under the effect of the displacement generated by the support of the lock body on the pinch during his introduction into housing. The rod then engages the corresponding hole

  in the wall of the front compartment of a charger in place or, failing that, prohibits any charger introduction.

  The setting up of this lock, made up of two coaxial parts whose separation from the key can only be done in closed position, ensures the implementation of four security: - relaxation by locking resulting from the establishment prior and compulsory lock-contra-detente before introduction of the lock in its housing, - bolt lock resulting from ['introduction of a stop (fete lock) limiting its course and prohibiting any chambering cartridge, loader by locking of the well resulting from the displacement of the rod (115) preventing any withdrawal or insertion of a magazine,

  disassembling the weapon by immobilizing the trigger guard bolt.

  MONOBLOC REFERENCE BODY (Plate 23/28).

  The breech of the weapon according to the invention comprises an ammunition ejection window opening on the lateral side.

  right without encroaching on the top of the breech.

  This position is possible thanks to the use of ammunition without ammunition conuairem with the conventional munitions which

  impose on the other weapons, an oversized ejection window encroaching on the top of the breech.

  This specificity can be used to equip the weapon with a target member (fig.25) consisting of a rail or rail (117) monobloc profile U with a handlebar at one end, secured to the cylinder head by a pivot (122) passing through said cylinder head at the height of the handlebar (120) and by a piece providing a connection (119) between a solid micrometer screw of the cylinder head and said rail, said piece having a vertical axis (123) passing through said cylinder head to engaging a blind hole arranged on the underside of said rail, which hole communicates with the

  receiving housing a flat circlip (121) which, in place, engages the groove of 1'axe (123) it locks.

  This aiming member can advantageously be painted, in the hollow of the rail and over its entire length, of appropriate color so as to facilitate instinctive shooting. It ends with a handlebar located in the extension of the rail and painted a different color on its profile cate shooter, so that it enjoys an immediate appreciation of the increase to apply To this end, the control of the target is facilitates the simple dosage of the portion of handlebar (120) to go beyond the center of the U shape by the profile of the rail. The latter is white paint highlights for

  to facilitate visual acquisition.

  The setting of the firing site is carried out by means of an endless micrometric screw (118), located at the end and in the interior of the yoke, perpendicular to the plane of symmetry of the weapon, which cooperates with the piece (119). of segdarization with the rail of aime. This piece (119) consists of a body in which the worm moves, overcomes a vertical axis which passes through the upper wall of the cylinder head and is fixed in the aiming rail. In order to take into account the radius of curvature of pivoting of the aiming rail during adjustment, the passage opening of the axis of the workpiece (119) of

  Gaison has a curvature with the same center (122) as the target rail.

  The micrometric screw has a cygndre shape supporting the endless threading and comprises a slot for receiving a screwdriver head at its end opening towards the outside of the weapon, the other end being housed in a blind hole of the bolt , is provided with hemispherical housing housing the head of a ball-cage (118 bis) on

the circumference of its plane face.

  The ball ball is housed in the bolt body, along an axis parallel to that of the screw, and in such a way that its head opens into the blind hole of the screw and bears on the lateral face of this screw. behind in order to

closer the target correction.

  The screw (118) is mounted idle in its housing and has a circlip positioned inside the breech in order to

keep it in his home.

  The connecting piece (119), moved by the micrometric screw, ensures the angular displacement of the aiming rail.

  The head of the flat circlip (121) may advantageously comprise the marking paint of the target rail entry.

  Note: the connection of the vertical axis (123) of the connecting piece (119) with its corresponding blind hole of the rail can, without changing the nature of the invention, be au vis or benefit from the possible elasticity of the material

  component said axis to provide the link by reversible clip.

  TELESCOPIC GUN (Plate 24 & 25/28, Figs 26 & 27).

  The weapon according to the invention may incorporate a telescopic gun device for increasing power,

  precision and range of ammunition without a case.

  This device consists of a telescopic barrel (138) with automatic extension slidably mounted inside a second barrel (140) and held in retracted position by a return spring (141). The inner barrel (138) has the shape of a hollow cylinder of inner diameter adapted to the caliber of the munition and comprises two sections (138 bis) and (138 ter) contiguous and coaales of outer diameters apses cooperating respectively with the diameters of the shoulders (140 bis and 140 ter) of the outer barrel (140) within which slides

internal barrel.

  The two wind guns are inserted into one another in such a way as to make a sliding telescopic mounting thanks to a contact surface constituted by the cylindrical part or bearing of larger diameter (138 bis) of the inner barrel (138) in contact with the cylindrical portion of greater internal diameter of the outer barrel (140 ter) and the smaller diameter portion (138 ter) of the inner barrel in contact with the inner wall of the cylindrical portion or bearing (140

  a) small diarnetre of the outer barrel.

  The adjustment of the parts in contact is likely to promote a tight connection with the minimum of friction. The

  internal barrel may have scratches on its inner cylindrical part as on most guns.

  The connection between the two guns is such as to allow axial sliding and prohibit any crazy rotation of a cylinder relative to the other. For this purpose, the outer surface of the inner barrel is characterized in that it comprises on its lower diameter portion (138 ter) a number of rectilinear or helical grooves cooperating with grooves syrnetriquement amenageses on the inner face of the part cylindrical of smaller diameter (140

  bis) of the outer barrel with which it cooperates.

  The end of the larger inner diameter of the outer cylinder (139) has an external thread for cooperating with a symmetrically threaded thread in the cradle (107) of the carcass of the weapon. A pin

  ensures the braking of the barrel-cradle connection.

  A return spring (141) for ensuring the retracted return of the inner barrel is mounted prisoner between the inner and outer barrels. Surrounding the inner gun (138 ter), its wind extremities resting on the faces (138)

  1 5 bis and 140 bis) radial of each door or bearing of the internal and external guns.

  In order to prevent any deterioration of the return spring during the compression produced by the extension of the inner barrel, the outer cylinder comprises an internal shoulder or shoulder (142) against which the front face of the

  cylindrical part of large diameter (138 bis) or bearing of the inner barrel abuts at the end of the race.

  The assembling of the assembly is particularly simple and easy: to pass the recuperating spring around the inner barrel (138) then to introduce the assembly into the outer barrel (140) which is then screwed into the housing of the

cradle (107).

  The rear face of the inner barrel opens into the ammunition chamber and has a conical funnel (143) for receiving the ball. This funnel has an inlet diameter close to that of the inner diameter of the outer barrel in order to eliminate any pressure of the gases which tends to be exerted parallel to the axis of the barrel and to

  pushing said telescopic barrel outward and unnecessarily increasing the recur of the weapon.

  Principle of operation of the telescopic barrel (Fig. 26 & 27).

  During the firing of the ammunition the beautiful is propulsed in the conical collector (143) of the telescopic gun (138) whose friction with said beautiful entails a transfer of energy causing its progressive extension

(Fig. 27).

  Advancing the telescopic barrel significantly increases the size of the ammunition chamber for better combustion of the propellant as much as an increase in propulsion time of the beautiful and its guidance: the output power of mouth sten is increased in proportions similar to those produced by a classic

  increased length of the barrel of a weapon.

  The extension of the telescopic barrel occurs simultaneously with the recur of the breech, compensating by projection of

  mass forward of the weapon recur in proportion to the mass of the telescopic barrel and its output speed.

  The telescopic barrel thus produces an anti-recur effect particularly conducive to the stability of the shot, especially in continuous fire. As soon as the beautiful is out of the telescopic barrel this one returns in retracted position under the effect of the spring

  recuperateur, ready to welcome a new ball.

  BENEFITS OF THE WEBSITE DA E Ch. 26, 27 & 28/28).

  The introduction of electrical energy and microprocessors leads to a simplification of the mechanisms, thus a gain in weight, and the integration of particularly important new functions: detection of cartridge presence in the barrel, selection of shot-by-shot or burst directly from the detente, - selection of the number of ammunition fired by burst, - counter restarts shots, - counter shot by accredited shooter, - total counter shots shot (cannon wear), - clock: date and time of the shots - recording: the central computing unit has a memory capacity allowing to restore all the elements of a shot (person, date & time, number of cuts ...), - firing safety by automatic recognition of the fingerprint fencer (or fencers) accredited, - programming (enlisting) personnel authorized to use the weapon, - automatic detection of the type (short, long ...) of the magazine engaged in the weapon,

  - battery charging display.

SELECTION OF TTR (Plate 26/28).

  A fire selector (81) has two positions << S >> (for SINGLE or shot by blow) or a pictogram representing a munition and A or AUTO (for automatic) or a pictogram representing several ammunition, may be

  installs on one of the side walls of the grip to guarantee the shooter the absolute control of the shot gust.

  This selector may have several additional positions corresponding to the number of ammunition fired during a burst. This number of ammunition can be indicated by the addition of a number or as many ammunition

stylized around the selector.

  The jogging position will inhibit the function of the second switch or the full force position of a single

  switch has two levels of the electric detente.

  In the case of continuous fire, the detent being fully pressed, the recording of the effective and full closure of the cylinder head by a contactor type microswitch (128), optocoupler ... located, for example, at the junction (Fig. 28)

  carcass / yoke entrains the delivery of the desired tension to the touchau (igniter / ejector) mandrel.

  A rotator waterproof at three positions and whose axis would be coincident with that of the detente would perform the same functions without changing the nature of the invention. The shot / blow or burst selection is then made by

  Progressive enforcement of the detent tail, eliminating the presence of the selector (81).

VTSUALTSATTON OF FUNCTTONS

  The weapon includes a screen displaying the following information: presence of a munition in the room, - number of ammunition remaining, - authorization of shooting, - selection: blow / blow or burst, - date & time, name (or code ) accredited shooters,

- battery charge.

  In order to obtain essential information (shooting authorization, number of remaining cartridges, firing selection), the screen will be advantageously located (Fig. 29, N 132) at the rear of the weapon's breech, just below the target. visor, of course, one has to be permanently visible when the weapon is in its case or, in particular, in line of aim before a tin

  A micro-button has enforcement will scroll through the various functions on the screen.

RECORDING OF SHOOTING

  The electronic circuit of the weapon comprises a clock and a memory whose information can be viewed on interrogation of said memory via a port, located inside the bolt, connection to an accessible computer

  after introduction of a charger vice and recur of the breech (causing its blocking in the rear position).

  The processing of this memory makes it possible to restore all the elements of use of the weapon: - date & time of the shots, - selection (blow / blow or burst), - identity of the shooter, - number of munitions drawn, - date & time of personnel accreditations, - total ammunition drawn over a period (eg year),

  - statistics (aging cano4 weapon).

  Countdown function (fg 28 & 29).

  The knowledge of the number of hits restarts in a weapon has always been crucial information for the shooter.

  The absence of counting system still forces today the user has a different calculation between shots.

  consume and the initial capacity of the weapon to know the number of ammunition remaining.

  In order to facilitate the determination of the number of restarts, the weapon includes a device for counting ammunition presented by recording the presence of a munition in the chamber and knowledge of the position.

  front and rear carriers of the loader.

  Since the use of an incomplete magazine can only be justified in the context of a training, it is sufficient to know, for an operational use, the high or low position of the carriers of each compartment to deduce the number of shots. restarts before a tin For this purpose, the loader well is provided with contactors (130, 131) located in the carcass at the top and in the teas of the

  sliding groove of each carrier button.

  The position information of each button thus collected is transmitted to the central microprocessor which assigns a value, contained in its memory and abunted by the detection of a possible presence of cartridge in the barrel, of

  overall capacity of the weapon with the magazine.

  The distinction between the various models of chargers (short, long ...) follows the same principle: a switch (129) located in the well of the weapon allows the central computing unit, if it is actuated, to recognize the type of loader engaged and display actual information according to the position of the carriers and the information of

  presence of a cartridge in the barrel.

  With each shot the calculating unit (microprocessor) decreases the amount of ammunition the total calculates and brings to the screen the result. This method, inexpensive in terms of productio4 does not, however, to know the capacity

  snapshot of a partially lined loader engages in the weapon.

  To this fi4 the loader well may comprise a scale of sensors detecting the passage of a marker (magnetic, electroluminescent ...) located on the carrier of each compartment. The spacing between each

  sensor corresponds to the movement of the carrier when removing a cartridge from the corresponding compartment.

  The referencing of the position of each sensor will allow the central unit to determine the capacity of each compartment and to fill it with the possible presence of a cartridge in the barrel to deduce the

capacity of the weapon.

  Note: The number of shots is determined by the number of decbAges actually recorded in the

  touching firing (there is no electrical contact in ['absence of cartridge].

  MORPHOLOGICAL IDENTIFICATION OF A TIREUR

  In order to allow shooting only by the actual holder of a weapon or any accredited person, a fingerprint recognition device is incorporated in the central block (133) located in the cylinder head, behind the chuck of

* firing (124).

  This device is coupled to a substrate (123), ensuring the detection or analysis of the characteristic points of

  The fingerprint, applies to the front of the tail of relaxation.

  The system is active only when the contra-relaxation security is off, causing a slight recur of the detent that squeezes the general switch (125) for energizing the weapon circuits, located behind the nearby detent. shot-to-shot (126) and burst (127) fire contactors. The identification module is then under

  tension and its role and to authorize the firing after a positive identification of the fencer's fingerprint.

  Note: the ignition switch and the gun contactor can be switched on

  advantageously be integrated in a two-level switch or in a rotator (125 bis).

Enrollment procedure.

  In order to ensure continuous control and monitoring of users (individuals, administrations, armed forces, special forces), a procedure for the enlistment or storage of fingerprints is established following a

  accreditation principle at two levels.

  For this purpose, the memory capacity of the identification block is divided into two compartments, one of which (136) is

  reserved for the registration of the prints of the authorized personnel and the other (135) for that of the authorized personnel.

  First level. This level corresponds to the level of privates clearance by the competent authorities to carry out accreditations of the use of a weapon. This operation is made impossible for any user who would not have been

designate as such.

  For this purpose, the compartment (136) corresponding to the memory of the identification block is accessible only by a port (137) located inside the bolt of the weapon and the storage of fingerprints desired s after

  unlocking access to said memory via software (PC) and a special connection cable.

  This software locks, via a code, the access to the memory compartment for a period of time (some

  minutes) sufficient to allow the user to be wound up.

  Accreditation procedure: - remove the lock of the total lock of the weapon, - remove the magazine and check that no ammunition is present in the chamber, - pull back the cutasse and block it with the breech stopper , - connect the cable connecting the computer to the port located inside and behind the bolt, - initialize the unlocking software and enter the identification code of the authority then the name and code

  identification of the person to live.

  - wait for the confirmation beep of the alarm, - make sure that the anti-relaxation is unlocked, - put the finger of the person to be enabled on the detente, - wait for the mark of the end of the energetic cycle (beep), - disconnect the wire from the breech port,

  - the weapon is usable by the new ability only.

  Note: this procedure, which can take place on the premises of the administration (police station ...) is particularly adapted to the diffusion of the weapon via the classic networks of distribution (gunsmiths ...), or the code

  The personnel of the future holder of the weapon shall be directly addressed to him by the administration.

  Senle the inhabited person (to the exclusion of any other) can then use the weapon. A period of validity may be introduced in order to obtain the user to be periodically passed by the services of the authority to unlock

his weapon.

Second level.

  This level allows the transfer of habitations from an "enabling" authority to a user using a simplified procedure, which does not require any wiring of the weapon to a computer so that it can be used quickly by

  operations. No transfer power of accreditation is then assigned to the new authority.

  Quick authorization procedure: - remove the total lock lock from the weapon, - remove the magazine and check that no ammunition is present in the chamber, - unlock the contra-detente, initialize a sequence by performing a number predefined (for example five) of complete and successive pressures on the detent tail, affixing the finger of the enabling person on the detente, - waiting for the authorization signal of energetic (beep), - in the XX seconds (for example thirty, the authorizing of termination ceases after this time), to put the finger of the new user for five seconds on the relaxation, - the emission of a new beep confirms the enrolement (only one possible) of the new user and l opening of a new enrolement sequence,

  - The absence of fingerprints on the trigger during a winding sequence automatically clatters it.

  The weapon can only be used by the empowering and empowered person.

  Note: this secondary authorization procedure is discretionary Only the administrations concerned will have this quick authorization possibility whose implementation is carried out via a specific code issued by

by the manufacturer.

  RESISTANCE TO ELECTROMAGNETIC LIGHTING AND OTHER COTS OF DUCTION

  The next weapon [the invention must be able to operate irreproachably regardless of the conditions

  environmental (violent thunderstorms, high-power radar radiation, nuclear electromagnetic flashes ...).

  For this purpose, the necessary shielding of the vital elements (central unit of calculation, memories of the block

  identification ...) will be adopted to ensure perfect insensitivity to these phenomena.

  ADVANTAGES OF THE WEAPON AND THE AMMUNITION FOLLOWING THE INVEON

  The weapon and the ammunition according to the invention have many advantages compared to current solutions, particularly in terms of precision and firepower. These benefits are listed as follows

Precision.

  The gun is mounted either fixed, rigid, or sliding in its cradle eliminating de facto any problem of

  repositioning and stalling between shots as on most weapons in use.

  The telescopic barrel device also contributes to this precision by providing an extended guide path of

the ammunition.

Sicur te.

  Reliability superior to that of ammunition weapons which have their base in the open air when fired, exposing the shooter to the risk of bursting of the wall of the case and the primer. The present patent, on the other hand, is based on a principle of charging the ammunition in a sealed chamber and confined with the benefit of the thickness of the walls of the

barrel and sealing piston.

  Relaxation security, the latter being composed of a "contradétente" especially innovative since it

  A quick implementation of the hand holding the weapon, and this in a completely ambidextrous way.

  Comfortable, simplified and economical storage: limited to ready-to-use ammunition. The removal of the procedures of

  Collection, processing and repackaging of the cases is synonymous with substantial savings.

  Quadruple lock of the stop by introduction of an arnovible lock ensuring the blocking of the relaxation, the

  cylinder head, the magazine well and the disassembly lock.

  Systematic habilitation of shooters making the weapon according to the invention the real answer to the problems

  unauthorized employment or misappropriation.

  OperationneL Use Space and reduced weight: the principle of ['invention allows to house the recuperator spring, ensuring the return of the slide in closed position, around the barrel. This arrangement is particularly advantageous in terms of congestion since it avoids the use of a guide rod as on most current weapons that

  operate by recur combines gun and slide.

  The weight of the weapon and its size benefit from the removal of this piece. For example, the realization of an automatic pistol according to the invention would lead to a weight of the weapon, charger feeds a

  forty cartridges included, less than 700 grams.

  Advantages of the tandem loader: the tandem arrangement of the compartments and the three piles of ammunition

  can take up to three times the capacity of current chargers, more than forty cartridges.

  This device focuses the firepower of a submachine gun into an automatic, opening the flies to a

  new march of compact and light weapons has the extraordinary power of fire.

  Unparalleled discrepancy due to the absence of traces (casings) at the end of a tin Reinforced efficiency of ammunition which benefits from a reduction in weight and bulkiness of up to 50%

  classic ammunition and this has equal performances.

  Increased firepower: For the same weight of ammunition, the effective mass (or projectable) is equal

  50% more than with ammunition.

  Elimination of the risk of jamming at the ejection of cases.
