NO345965B1 - Hydraulic rotor motor - Google Patents

Description

Designation

"Hydraulic rotor motor"

Application

Hydraulic rotor motors are an alternative to today's piston motors, and can be used where there is a need for motors.

As the engine type does not use compression to ignite the fuel, there are more fuel options than in the piston engine.

The position of the technique

Hydraulic rotor motor is a further development of the "Center-fed rotor motor", which is described in patent NO 345283 B.

Patent NO 345283 B builds on the technology in patent NO 20180636 A, "Center-fed vane turbine". Patent US 2010170469 A1 shows a rotor engine, but is without a central chamber where the fuel is supplied and ignited, and is different from what is described in the introductory part of this patent application. Hydraulically controlled buckets are not the subject of patent US 2010170469 A1.

Patent US 4072132 A is a rotor engine where pistons create compression using a sliding mechanism, and therefore work according to a different principle than that described in this patent application.

Patent US 2008310985 A1 is a rotor motor with an eccentric rotor, and therefore also fundamentally different from this patent application.

The new

1 By using hydraulic pressure to move the vanes, the rotational speed can be increased, and the power will be greater with the same size of the motor.

2 By using a smaller explosion chamber, fuel consumption will be lower.

3 By connecting several rotor motors to the same shaft, the motor will have more even torque.

The formula 360/number of motors determines how many degrees the motors must be offset in relation to each other, and the patent application describes a variant with 3 motors, which means that each motor is twisted 120 degrees.

Explanation

As what is sought to be patented are improvements to patent NO 345283, the explanation has fundamental similarities with this patent.

Fuel is supplied to the explosion chamber (E) through the pipes (f1) and (f2) and is ignited to create pressure, which is directed to the vane chamber (g) through an opening in the center chamber (h). The pressure is utilized by the vanes (w) which create torque for the rotor (B).

The exhaust gases are released through the opening (q) in the housing (A).

Rotor (B) has the rotor top (b) and the ring (s), and between them are mounted rods (r), which determine the length of the vanes (w).

Figure 5 shows that the vane chamber (g) has a channel (K) which lets the rods (r) and the vanes (w) through when they are in transport position.

The air intakes (C) have non-return valves (d) which are hinged on the air intake ring (e). The air intakes (C) must lead air into the explosion chamber (E) and center chamber (h) when the pressure is lower than outside the rotor motor.

The spacers (c) in housing (A) are fitted with a distance to allow air to air intake (C).

The explanation further deals with what is new and which is wanted to be patented.

In the bottom (k) of the housing (A) are channels for hydraulic fluid, as shown in figure 5, where high pressure is supplied through channel (u1), with return through channel (u2). The vanes (w) are fixed in a circular sealing plate (z) which can move in the rotor top (b), and the vanes (w) are controlled by a hydraulic piston (x). Figure 9 shows vane (w1) with piston (x1), which moves in piston chamber (P1). The hole (H) shows how the hydraulic pressure is supplied to the piston chamber (P). The pressure in channel (u1) is led to the center liner (j) and recess (R1), and is supplied to the rotor (B) through hole (T), shown in figure 4, and to channel (u3). Piston (x1) then gets the position shown in figure 9, and vane (w1) gets an active position. Return of hydraulic fluid is through channel (u4) and further through a hole (T) on the opposite side of the rotor shaft (t) and through channel (u2) and back to the hydraulic pump.

The freedom of movement of the piston (x1) is determined by the stop (v1), fixed in the rotor top (b), as shown in figure 3.

A hydraulically controlled movement of the vanes (w) means that the revolutions can increase without the vanes being damaged by physical contact with the guide rails (M), and is a significant improvement to increase revolution speed and power.

The hydraulic device works in that 2 holes (T), mounted opposite each other on the shaft (t), are adapted to the grooves (R1) and (R2) in the center liner (j) in the housing (A).

(S1) and (S2) in Figure 6 show the contact points between the center liner (j) and the rotor shaft (t).

When the rotor moves, the holes (T) will alternately be in the grooves (R1) and (R2).

Piston chamber (P) is closed by lids (D1) and (D2) which are fixed in rotor top (b).

Piston (x) will then move from one outer edge to the other, controlled by rotor (B).

Piston (x) is fixed in the vanes (w) through center plate (i) and sealing plate (z).

The channels (u3) and (u4) are connected to each side of the piston chamber (P).

As the 2 openings (T) are positioned diagonally opposite each other on the rotor shaft (t), the vanes (w1) and (w2) will change position at the same time.

The channels (R1) and (R2) are separated from each other by the goods in the center lining (j) at points (y1) and (y2), as shown in figure 6, which then separates high pressure from low pressure.

When the holes (T) are at (y) the vanes (w1) and (w2) are unaffected, and the time is just before the vanes (w1) and (w2) change position.

Each vane (w) has an active position and transport position in each revolution.

The torque from the active bush (w) is transferred to the piston (x), and further to the stop (v) in the rotor top (b).

Rotor top (b) transfers the torque to shaft (t), which has mounted gears and power take-off.

The second significant improvement is achieved by the central chamber (h) being divided by a plate (m), so that we get a smaller explosion chamber (E) and reduced fuel consumption. The explosion chamber (E) is closed with hatch (p) just before the fuel is added.

The hatches (p) and (n) are controlled by electromagnets and close simultaneously, but only the hatches (n) are opened by the pressure when the fuel is ignited.

Power is supplied through connection (f3).

Figure 10 shows hatch (n1) in closed position and hatch (n2) in open position. Explosion chamber (E), under plate (m), is closed against center liner (j) and inner wall (N) in housing (A).

A 3rd significant improvement is shown in figure 11, where several "rotor motors" are mounted on the same shaft, rotated in relation to each other according to the formula 360/number of rotor motors.

This improvement leads to smoother torque.
