DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speed change mechanism and a rotary piston to which the movement is applied.

[0002]

2. Description of the Related Art Conventionally, as a speed change mechanism with an accurate speed ratio,
Gears, chains, timing belts, etc. have been used, but relatively high precision was required mechanically. Further, the piston has drawbacks such as easy vibration, otherwise poor sealing characteristics, or unsuitability for high-speed operation. Also, the only commercially available rotary piston engine is the Wankel engine, which is also difficult to achieve high compression due to sealing problems and is not energy efficient. There were drawbacks including:

[0003]

SUMMARY OF THE INVENTION The present invention realizes an inexpensive transmission with an accurate gear ratio and, by applying the operation of this mechanism to driving of a piston, can achieve a sealing characteristic comparable to that of a reciprocating piston. The purpose is to supply inexpensive, high-performance rotary pistons to the market.

[Means for Solving the Problems]

In FIG. 1, a rotating arm shaft (2) and a pin A (4) are integral with a rotating arm A (3), and a rotating arm A (3)
Is supported by a bearing A (1) and can rotate about a rotary arm shaft (2). The turntable axis (7) is a turntable A
The turntable A (5) is a part of (5), and is rotatable around the turntable shaft (7) supported by the bearing B (6). The turntable A (5) has a groove, and the pin A (4) is fitted in the groove, and the turntable A (5) or the turning arm A (3) is provided.
When one of the shafts is rotated, the pin A (4) transmits the rotation to the other while sliding in the groove, and the rotating arm A
(3) and the turntable A (5) rotate simultaneously. The rotation axis of the rotary table axis (7) is different from the rotation axis of the rotary arm axis (2), and the rotation axis of the rotary table A (5) is rotated by the rotation of the rotary arm A (3) to the center of the pin A (4). It is assumed that it exists inside the trajectory cylinder created by the line. FIG. 2 shows the rotation of FIG.
This is shown for each 0-degree rotation. From this figure, it can be seen that when the rotary arm A (3) makes one rotation, the turntable A (5) also makes one rotation. FIG. 3 shows the groove in FIG.
The piston A (10) integrated with the piston drive rod (9) can be slid in the cylinder A (11) in place of 1). The cylinder A (11) is fixed to the turntable B (12), and the tip of a pin B (13) is fitted in a hole of the piston drive rod (9) to rotate the rotary arm B (8). Then, the turntable B (12) is also rotated, and the piston A (10) slides in the cylinder A (11) to change the volume of the space created by the cylinder A (11) and the piston A (10). I do. I mean

3 executes a piston operation by a rotational movement of each part.

FIG. 1 shows a rotary arm A (3) and a turntable A
Although the number of rotations in (5) is the same, the relative angular velocity between the rotating arm shaft (2) and the rotating table shaft (7) constantly changes during rotation. This change is a factor that hinders smooth rotation of the mechanism. In order to eliminate this disadvantage, according to the desired rotation ratio

As shown in FIG. 4, the shape of the groove may be devised.

It is difficult to replace the piston A (10) of FIG. But,

FIG. 5 shows a straight groove if the center locus of the pin of the rotating arm C (14) and the center line of the groove are in contact with the rotation center point of the rotary table C (15) in a plane. The angular velocity ratio between the rotary table C (15) and the rotary arm C (14) can be kept constant. this is

In FIG. 5, it can be proved as follows. AB = AC Therefore ∠ABC = ∠ACB or ∠ABC + ∠ACB = 2R-∠CAB ∠DAC = 2R-∠CAB ∴∠DAC = 2∠ABC は DAC = 2∠ABC means that the turntable C (15) rotates. However, since the relationship always holds, the relative angular velocity ratio between the two rotating shafts is constant at 2: 1. Also,

FIG. 3 shows a piston A (10) and a cylinder A
Since the rotation angular velocity of (11) is the same,

FIG. 5 shows a structure having a relationship as shown in FIG. 5, in which the angular velocity ratios of all the rotating bodies are always constant, and the smoothness of the rotation is hardly impaired. still,

5A is a rotation center point of the rotating arm C (14), FIG.
B is the rotation center point of the turntable C (15), C is the center point of the pin, D is the point where a straight line including A and B intersects the outer periphery on the left side of the turntable C (15), and the diameter of the pin is It is the same as the width, but it can slide freely in the groove.

When the mechanism of FIG. 5 is used for a transmission, when the center line of the groove circumscribes the locus circle formed by the center of the pin in a plane,
Normal communication may not be possible, but to prevent this

5 may be used by connecting a plurality of mechanisms in parallel so that the angles of the respective grooves are different. Also,

The same effect can be obtained by increasing the number of grooves and pins as shown in FIG. The present invention

FIG. 3 shows that the stroke of the piston A (10) used is proportional to the revolving diameter of the piston A (10). Therefore, if this diameter can be changed steplessly, the piston Can control abilities.

FIG. 7 is a structural conceptual view (partially perspective view) for realizing this (this figure is provided with a total of four cylinders, but in principle one or more cylinders are sufficient). This structure also

3 has the advantage that the rotary arm B (8) can be omitted and the device can be downsized.

FIG. 7 illustrates that four tips of a cross-shaped piston A (23) having a shape in which two cylindrical pistons are integrated,
They are inserted into cylinder A (19), cylinder B (22), cylinder C (24), and cylinder D (26), respectively. The cylinder A (19) and the cylinder C (24) are mounted on the turntable E (20), and the cylinder B (22) and the cylinder D
(26) is fixed to the turntable F (18), respectively. When the positions of the rotary shaft E (21) and the rotary shaft F (25) are supported and rotated, the rotary table E (2
If the position of the rotation axis of the rotary table F is different from that of the rotary table F, the piston operation is performed. At this time, the cross-shaped piston A (23) revolves while rotating, and the trajectory (revolution trajectory) of the center point of the rotation is the rotation axis of the turntable E (20) and the rotation axis of the turntable F (18). Connect with the heart. Therefore, the turntable E
If the distance between the axis of the rotary shaft (21) and the axis of the rotary table F (25) is changed, the revolving diameter of the cross-shaped piston A (23) is changed, so that the piston performance can be controlled. And it is not so difficult to make the structure that can change the distance between the axes even during the operation of the piston. Also, the relative angular velocity ratio between the two turntables does not fluctuate. still,

When the structure of FIG. 7 is applied to an internal combustion engine, it is advantageous to reverse the directions of the piston and the cylinder in terms of lubrication. Also,

FIG. 7 shows the structure and movement of each part very similar to those of the Oldham coupling. If the airtightness of the piston does not matter much

FIG. 7

FIG. 8 shows a structure as shown in FIG. Also

If the rotation of the two shafts is connected by a gear or the like as in FIG. 9, the stress and friction applied to the piston can be reduced.

[0005]

DETAILED DESCRIPTION OF THE INVENTION

FIG. 4

If the mechanism shown in FIG. 5 is used, a transmission with an accurate rotation ratio can be manufactured at low cost, and the structure is simple, so that it is suitable for use in small equipment.

FIG. 10 shows a pump according to the present invention,

FIG. 11 is a structural conceptual diagram of an example used for an internal combustion engine.

FIG. 10 explains the pump operation: 1) If the turntable K (37) and the cross-shaped piston C (36) rotate clockwise in the BB 'cross-sectional view, the state shown in FIG. When the rotation proceeds a little from this point, the suction / discharge hole C is connected to the suction groove B. Since the volume of the chamber C increases with the progress of the rotation, the fluid flows into the chamber C via the suction port B and the suction groove B. This is because the suction and discharge holes C are overpressure prevention pieces B (4
2) It rotates to the vicinity and continues until it is cut off from the suction groove B. 2) When the rotation further proceeds and the suction / drain hole C is connected to the delivery groove B, the fluid in the chamber C is pushed by the cross-shaped piston C (36), passes through the delivery groove B, and is discharged from the delivery port B. You. This continues until the suction / discharge hole C reaches the vicinity of the overpressure prevention piece A (41) and is cut off from the delivery groove B. 3) 1) and 2) are repeated with the rotation of the turntable K (37) and the cross-shaped piston C (36). 4) The operations 1) to 3) are performed similarly in the room D,
As a result, it operates as a pump. 5) The operations 1) to 4) are performed in the same manner in the turntable L (40). I mean

FIG. 10 has two pumps inside. still,

FIG. 10 is a sectional view taken along the line BB 'when the suction / discharge hole C or the suction / discharge hole D of the turntable K (37) passes through a portion shielded from both the suction groove B and the discharge groove B; Chamber D is sealed but the volume continues to change. Therefore, water and oil
In the case of handling a fluid whose volume does not change by pressure, an overpressure prevention piece A (41) and an overpressure prevention piece B
Providing two small chambers each containing (42), or
It is appropriate that b ≦ a and c ≦ d / 2. By doing so, the former absorbs the change in the volume of the chamber C or the chamber D by changing the volume of the elastic body, and the latter absorbs a large volume of the chamber C or the chamber D on the right side of the BB 'sectional view. When changing in a certain direction, a vacuum appears by the amount of the change, and when it starts to decrease, the vacuum operates with a reduced volume. On the left side, while the volume of the chamber C or the chamber D is decreasing, the chamber C or the chamber D is connected to the discharge groove B. When the volume of the chamber C or the chamber D increases, the chamber operates while creating a vacuum inside.

FIG. 11 is an explanatory diagram of a system in which the present invention is applied to an internal combustion engine. In this figure, the turntable M (4
6) and the turntable N (51) are both cross-sectional and spaced apart, but the actual arrangement is

8 is the same as that in FIG. 8 (the turntable N (51) side is on the left rear side). Assuming that the turntable M (46), the turntable N (51), and the ten-hour piston D (47) rotate clockwise.

11 is described below. 1) As the rotation advances from the position shown in the figure, the suction hole D and the suction groove are connected, and as the rotation advances, the volume of the compression chamber B increases. , Air flows into the compression chamber B. This operation continues until the rotation advances and the suction hole D is cut off from the suction groove. 2) When the rotation further proceeds and the delivery hole B is connected to the delivery groove, the air in the compression chamber B is pushed out by the delivery groove and stored in the air chamber (48) while being compressed. This operation is similarly performed in the compression chamber A, and is repeated with the rotation of the turntable M (46). 3) In the turntable N (51), when the suction / discharge hole A is connected to the compressed air intake, the air stored in the air chamber (48) flows into the combustion chamber A. This continues until the rotation proceeds and the suction and discharge holes A are shut off from the compressed air intake. 4) After that, the suction / discharge hole A is connected to the fuel injection chamber, and the fuel is injected by the fuel injector (50) and ignited by the igniter (49) (this igniter (49) is used in a semi-diesel engine). Such a coil that is always red hot can be used, so that an inexpensive device can be realized). 5) When the pressure in the combustion chamber A rises due to the combustion, the cruciform piston D (47) is pressed, so that a clockwise rotating force is generated on the turntable M (46), and the rotation is continued. 6) When the rotation proceeds and the suction / discharge hole A is connected to the exhaust groove, the gas in the combustion chamber A flows out from the exhaust port. And the turntable N (5
As the rotation proceeds in 1), the gas remaining in the combustion chamber A is pushed out into the exhaust groove by the cross-shaped piston D (47). This continues until the intake / exhaust hole A is shut off from the exhaust groove. 7) The operations of 3) to 6) are similarly performed in the combustion chamber B. still,

In FIG. 11, the capacity on the compression side and the capacity on the combustion side of the piston are made different to improve the energy efficiency.
Further, such a system can be realized by a conventional reciprocating piston, but it is not practical because the structure becomes complicated. The piston of the present invention can be used in addition to conventional pumps, internal combustion engines, hydraulic motors, compressors, etc.
Can be used for a wide range of applications. Also,

FIG. 7 shows a mechanism such that the piston capacity can be changed steplessly without changing the number of revolutions. If this mechanism is applied to a hydraulic motor or a hydraulic pump, a continuously variable transmission can be realized.

[0006]

According to the transmission, 1) the rotation can be reduced and increased with a simple structure without rotation slip. 2) It is possible to create a rotation with a change in the angular velocity. Rotary piston 1) Suitable for high pressure because a circular cylinder with excellent airtightness can be used. 2) Since there is no reciprocating motion in the basic operation, it is possible to manufacture a device having less vibration and reduce energy loss due to vibration. 3) Since the vibration can be reduced even if the piston stroke is relatively long, when used in a prime mover, both low-speed rotation and high-speed rotation can easily have good characteristics. 4) The structure can be simplified because a valve utilizing rotation of a cylinder or a piston can be used. 5) Stepless variable structure of piston capacity is easy.

In FIG. 1, a rotating arm shaft (2) and a pin A (4) are integrated with a rotating arm A (3), and the rotating arm A (3) is a bearing A (1). And can rotate around the rotary arm shaft (2). Further, the turntable shaft (7) is a part of the turntable A (5), and the turntable A (5) can rotate around the turntable shaft (7) supported by the bearing B (6). There is a groove in the turntable A (5), and a pin A (4) is fitted in this groove. When one of the axes of the turntable A (5) or the rotation arm A (3) is rotated, The pin A (4) transmits the rotation to the other while sliding in the groove, and the rotation arm A (3) and the turntable A
(5) rotates simultaneously. Note that the positions of the rotary axes of the rotary table axis (7) and the rotary arm axis (2) are different, and the rotary table A (5)
The rotation axis of the pin A is
It is assumed that the center line of (4) exists inside the trajectory cylinder created. FIG. 2 shows the rotation of FIG. 1 at every 90-degree rotation. From this figure, the rotating arm A (3)
It can be seen that one rotation of the rotation makes one turn of the turntable A (5). FIG. 3 shows the groove in FIG.
The piston A (10) integrated with the piston drive rod (9) can be slid in the cylinder A (11) in place of 1). The cylinder A (11) is fixed to the turntable B (12), and the tip of a pin B (13) is fitted in a hole of the piston drive rod (9) to rotate the rotary arm B (8). Then, the turntable B (12) is also rotated, and the piston A (10) slides in the cylinder A (11) to change the volume of the space created by the cylinder A (11) and the piston A (10). I do. That is, the mechanism shown in FIG. 3 executes the piston operation by the rotational movement of each part. The mechanism shown in FIG.
Although (3) and the rotation speed of the turntable A (5) are the same,
The relative angular velocity between the rotating arm axis (2) and the rotating table axis (7) constantly changes during rotation. This change is a factor that hinders smooth rotation of the mechanism. To eliminate this drawback,
The shape of the groove may be devised as in the example of FIG. 4 according to the target rotation ratio .
It is difficult to replace with 0). However, if the pin and the center locus of the rotary arm C (14), the center line of the groove is in contact with the center of rotation and the plane of the turntable C (15) structure as shown in "Figure 5", a straight groove But the turntable C (1
The angular velocity ratio between 5) and the rotating arm C (14) can be made constant. This can be proved from FIG. 5 as follows. AB = AC Therefore ∠ABC = ∠ACB or ∠ABC + ∠ACB = 2R-∠CAB ∠DAC = 2R-∠CAB ∴∠DAC = 2∠ABC は The relation of ∠DAC = 2∠ABC is that the turntable C (15) rotates. However, since the relationship always holds, the relative angular velocity ratio between the two rotating shafts is constant at 2: 1. Also, in FIG.
Since the rotational angular velocities of the piston A (10) and the cylinder A (11) are the same, if the rotational angular velocities are structured as shown in FIG. 5 , the angular velocity ratios of all the rotating bodies are always constant, and Smoothness is not often impaired. still,
“ A ” in “FIG. 5” is a rotation center point of the rotating arm C (14),
B is a rotation center point of the turntable C (15), C is a center point of the bin, D is a point where a straight line including A and B intersects the outer periphery on the left side of the turntable C (15), and the diameter of the bin is It is the same as the width, but it can slide freely in the groove.
When the mechanism shown in FIG. 5 is used in a transmission, when the center line of the groove circumscribes the locus circle formed by the center of the pin in a plane,
Normal transmission may not be possible. To prevent this, a plurality of mechanisms shown in FIG. 5 may be used in parallel connection so that the angles of the grooves are different. Also,
The same effect can be obtained by increasing the number of grooves and pins as shown in FIG . The stroke of the piston A (10) using the present invention as shown in FIG.
Since it is proportional to the revolution diameter of 0), if this can be changed , the capacity of the piston can be controlled as required. FIG. 7 is a structural conceptual view (partially perspective view) for realizing this (this figure is provided with a total of four cylinders, but in principle one or more may be used). this is
This is an application of the double slider mechanism.
3) Rotation arm B (8) and pin B (13) are not
In addition to the fact that the center contraction of the cylinder or piston is
Center line of E rotation shaft (21) or rotary table F rotation shaft (25)
The angular velocity ratio of the two rotating tables does not fluctuate even in a structure that does not touch
There are advantages too. Referring to FIG. 7, the cross-shaped piston A (23) having a shape in which two cylindrical pistons are integrated is referred to as “4”.
The two tips are cylinder A (19) and cylinder B, respectively.
(22), inserted into the cylinder C (24) and the cylinder D (26). The cylinder A (19) and the cylinder C (24) are connected to the turntable E (20), and the cylinder B (22).
And the cylinder D (26) are fixed to the turntable F (18). When the position of the rotating table E rotating shaft (21) and the rotating table F rotating shaft (25) is supported and rotated, the rotating table E is rotated.
If the position of the rotation axis of the rotary table F (18) is different from that of the rotary table F (18), the piston operation is performed. At this time, the cross-shaped piston A (23) revolves while rotating ,
The effective stroke is proportional to the size of the revolution diameter. This orbit
The size of the diameter is the rotary table E rotary shaft (21) and the rotary table F rotary shaft
Since it is proportional to the distance of the axis center of (25), change this
If you do, you can change the piston capacity. And it is not so difficult to make the structure that can change the distance between the axes even during the operation of the piston. Also, the relative angular velocity ratio between the two turntables does not fluctuate. It should be noted that, "Figure
When the structure 7) is applied to an internal combustion engine, it is advantageous to reverse the directions of the piston and the cylinder in terms of lubrication. The structure of FIG. 7 and the movement of each part are very similar to those of the Oldham coupling. If the airtightness of the piston does not matter much
"FIG. 7" may have a structure as shown in "FIG. 8" , and manufacturing is easy. If the rotation of the two shafts is connected by gears or the like as shown in FIG. 9 , the stress and friction applied to the piston can be reduced.

In addition, in FIG. 10 BB ′ sectional view, the suction and discharge hole C or the suction and discharge hole D of the turntable K (37) is the suction groove B.
And when passing through a portion shielded from both of the delivery grooves B,
The chamber C or the chamber D is sealed, but the volume keeps changing. Therefore, when handling a fluid whose volume does not change with pressure, such as water or oil, an overpressure prevention piece A made of an elastic material
It is appropriate to provide two small chambers each containing (41) and an overpressure prevention piece B (42), or to satisfy b ≦ a, c ≦ d / 2. By doing so, the former is room C or room D
The volume change of the elastic body is absorbed by changing the volume of the elastic body. When a vacuum appears and turns to a decrease, the vacuum operates in a decreasing volume. On the left side, while the volume of the chamber C or the chamber D is decreasing, the chamber C or the chamber D is connected to the discharge groove B. When the volume of the chamber C or the chamber D increases, the chamber operates while creating a vacuum inside.

As the volume increases, the volume of the compression chamber B increases, so that the air flows into the compression chamber B through the air inlet and the suction groove. This operation continues until the rotation advances and the suction hole D is cut off from the suction groove. 2) When the rotation further proceeds and the delivery hole B is connected to the delivery groove, the air in the compression chamber B is pushed out by the delivery groove and stored in the air chamber (48) while being compressed. This operation is performed in the compression chamber A
However, the same operation is performed, and is repeated with the rotation of the turntable M (46). 3) In the turntable N (51), when the suction / discharge hole A is connected to the compressed air intake, the air stored in the air chamber (48) flows into the combustion chamber A. This continues until the rotation proceeds and the suction and discharge holes A are shut off from the compressed air intake. 4) After that, the suction / discharge hole A is connected to the fuel injection chamber, and the fuel is injected by the fuel injector (50) and ignited by the igniter (49) (this igniter (49) is used in a semi-diesel engine).

In FIG. 11 , the capacity on the compression side and the capacity on the combustion side of the piston are made different to improve the energy efficiency. Further, such a system can be realized by a conventional reciprocating piston, but it is not practical because the structure becomes complicated. In addition, the piston of the present invention can be used for a wide range of applications such as a conventional pump, an internal combustion engine, a hydraulic motor, and a compressor.

If the mechanism shown in FIGS. 4 and 5 is used, a transmission having an accurate rotation ratio can be manufactured at low cost, and the structure is simple, so that it is suitable for use in small equipment. "Figure 1
"0" is a conceptual diagram of a structure in which the piston of the present invention is used for a pump, and "FIG. 11" is an example in which the piston is used for an internal combustion engine. The pump operation of FIG. 10 will be described. 1) If the turntable K (37) and the cross-shaped piston C (36) rotate clockwise in the BB 'sectional view, the state shown in FIG. When the rotation proceeds a little from this point, the suction / discharge hole C is connected to the suction groove B. Since the volume of the chamber C increases with the progress of the rotation, the fluid flows into the chamber C via the suction port B and the suction groove B. This is because the suction and discharge holes C are overpressure prevention pieces B (4
2) It rotates to the vicinity and continues until it is cut off from the suction groove B. 2) When the rotation further proceeds and the suction / drain hole C is connected to the delivery groove B, the fluid in the chamber C is pushed by the cross-shaped piston C (36), passes through the delivery groove B, and is discharged from the delivery port B. You. This continues until the suction / discharge hole C reaches the vicinity of the overpressure prevention piece A (41) and is cut off from the delivery groove B. 3) 1) and 2) are repeated with the rotation of the turntable K (37) and the cross-shaped piston C (36). 4) The operations 1) to 3) are performed similarly in the room D,
As a result, it operates as a pump. 5) The operations 1) to 4) are performed in the same manner in the turntable L (40). That is, FIG. 10 has two pumps inside.

If the mechanism shown in FIGS. 4 and 5 is used, a transmission having an accurate rotation ratio can be manufactured at low cost, and the structure is simple, so that it is suitable for use in small equipment. "Figure 1
"0" is a conceptual diagram of a structure in which the piston of the present invention is used for a pump, and "FIG. 11" is an example in which the piston is used for an internal combustion engine. The pump operation of FIG. 10 will be described. 1) If the turntable K (37) and the cross-shaped piston C (36) rotate clockwise in the BB 'sectional view, the state shown in FIG. When the rotation proceeds a little from this point, the suction / discharge hole C is connected to the suction groove B. Since the volume of the chamber C increases with the progress of the rotation, the fluid flows into the chamber C via the suction port B and the suction groove B. This is because the suction and discharge holes C are overpressure prevention pieces B (4
2) It rotates to the vicinity and continues until it is cut off from the suction groove B. 2) When the rotation further proceeds and the suction / drain hole C is connected to the delivery groove B, the fluid in the chamber C is pushed by the cross-shaped piston C (36), passes through the delivery groove B, and is discharged from the delivery port B. You. This continues until the suction / discharge hole C reaches the vicinity of the overpressure prevention piece A (41) and is cut off from the delivery groove B. 3) 1) and 2) are repeated with the rotation of the turntable K (37) and the cross-shaped piston C (36). 4) The operations 1) to 3) are performed similarly in the room D,
As a result, it operates as a pump. 5) The operations 1) to 4) are performed in the same manner in the turntable L (40). That is, FIG. 10 has two pumps inside. In FIG. 10 BB ′ sectional view, the suction / discharge hole C or the suction / discharge hole D of the turntable K (37) is
And when passing through a portion shielded from both of the delivery grooves B,
The chamber C or the chamber D is sealed, but the volume keeps changing. Therefore, when handling a fluid whose volume does not change due to pressure, such as water or oil, an overpressure prevention piece A (4
It is appropriate to provide two small chambers each containing 1) and the overpressure prevention piece B (42), or to satisfy b ≦ a and c ≦ d / 2. By doing so, the former absorbs the change in the volume of the chamber C or D by changing the volume of the elastic body, and the latter absorbs the change in the volume of the chamber B or B.
On the right side of the cross-sectional view taken along the line -B ', when the volume of the chamber C or the chamber D changes in a direction to increase, a vacuum appears by the amount of the change. On the left side, while the volume of the chamber C or the chamber D is decreasing, the chamber C or the chamber D is connected to the discharge groove B. When the volume of the chamber C or the chamber D increases, the chamber operates while creating a vacuum inside. FIG. 11 is an explanatory diagram of an example in which the present invention is applied to an internal combustion engine. In this figure, for the sake of explanation, the turntable M (45) and the turntable N (49) are both cross-sections and are drawn away from each other, but the actual arrangement is the same as in FIG. (The turntable N (49) is on the left back).
The rotary table M (45), the rotary table N (49), and the ten-hour piston D (46) are assumed to rotate clockwise as shown in FIG.
1) As the rotation proceeds from the position shown in the figure, the suction / discharge hole C and the suction groove are connected, and as the rotation proceeds, the volume of the compression chamber A increases, and the air generated by the vaporizer (44) A mixture of fuel and fuel flows into the compression chamber A through the suction groove. This operation continues until the rotation advances and the suction / discharge hole C is cut off from the suction groove. 2) After the suction / discharge hole C is blocked from the suction groove, as the rotation further proceeds, the volume of the compression chamber A starts to decrease. However, since the suction and discharge holes C are closed, the air-fuel mixture in the compression chamber A is compressed.
This compression continues until the rotation proceeds and the suction / discharge hole C is connected to the combustion gas passage A. 3) When the suction / discharge hole C is connected to the combustion gas path A, the air-fuel mixture in the compression chamber A is ignited. This ignition is performed by the ignition auxiliary device (47) at the time of starting. However, if the temperature in the combustion gas passage A becomes high after the start, the ignition occurs even without the ignition auxiliary device (47). After ignition, the combustion gas is stored in the heat retention chamber (48). 4) The same operation as in 1) to 3) is performed also in the compression chamber B. 5) When the rotation proceeds from the state shown in the figure and the suction / discharge holes A of the turntable N (49) are connected to the combustion gas path B, the combustion gas in the heat retaining chamber (48) flows into the expansion chamber A. The resulting combustion gas pressure
Since the force pushes the cross-shaped piston D (46), the turntable M
A rotational force is generated in (45). This turning force is the turntable M
(45), cross-shaped piston D (46), turntable N (4
9) Rotate. 6) The flow of the combustion gas into the expansion chamber A continues until the suction / discharge hole A is cut off from the combustion gas passage B. 7) Even if the suction and discharge holes A are cut off from the combustion gas path B as the rotation proceeds, the pressure in the expansion chamber A is higher than that of the expansion chamber B, so that the generation of the rotation force is continued by this pressure difference. This continues until the intake / exhaust hole A is connected to the exhaust groove. 8) When the intake / exhaust hole A is connected to the exhaust groove, the combustion gas in the expansion chamber A starts to be discharged from the exhaust port to the outside through the exhaust groove. This continues until the intake / exhaust hole A is shut off from the exhaust groove. 9) The operations 5) to 8) are similarly performed in the expansion chamber B. Since the internal combustion engine can have a structure capable of converting heat energy into rotational energy until the combustion gas expands sufficiently, energy efficiency equivalent to that of a turbine engine can be obtained in principle. Also, like water in the heat insulation room
Injecting a small amount of a liquid will increase energy efficiency.
There is an advantage that the operating temperature of the engine can sometimes be lowered. In addition, the piston of the present invention can be used for a wide range of applications such as a conventional pump, an internal combustion engine, a hydraulic motor, and a compressor. In addition, if the distance between the two rotating shafts is made variable in the structure shown in FIG. 7, the piston capacity can be changed steplessly without changing the number of rotations. If applied, a continuously variable transmission can be realized.
