Description

[Detailed Description of the Invention] This invention aims to replace the conventional internal heat engine and various power system devices used in connection with it with a new mechanism, and is intended to replace the conventional internal heat engine and various power system devices used in connection with it with a new mechanism, and to It can be made smaller, lighter, and cheaper than other engines, and since the power transmission medium is changed to gas, no clutch mechanism, transmission, propeller shaft, braking device, reversing gear, etc. are used. The purpose of this invention is to provide an extremely simple and highly efficient power device.

That is, unlike a conventional rotary engine, the power plant of the present invention has an air compressor, an output machine, and a combustion chamber separated from each other, and the compressor and output machine have a rotor in the center. The compressed air is sent to the combustion chamber and combusted by the change in the space volume inside the cylinder on the compressor side due to the rotation of the rotor, and the combustion gas is sent to the output machine and the expansion pressure of the gas is used. While rotating the output machine, most of the high pressure gas in the output machine is supplied to the gas tank,
Only a relatively small amount of the remaining gas acts on the output machine to generate rotational force, and the rotational force of the output machine rotates the rotor of the air compressor on the operating shaft and is sucked into the compressor. It is used to forcefully send air to the combustion chamber, and the air suction amount of the compressor can be adjusted arbitrarily, and the high pressure gas sent from the combustion chamber can be sent from the output machine to the gas tank. It has become.

In this device, the air sent from the compressor to the combustion chamber is combusted in a sealed state, and when the valve is opened after combustion, it is sent to the output machine side.

The combustion range at this time, that is, the size of the combustion chamber, can be set within an angular range of 100° to 180° along the circumferential direction of the output machine or compressor.

Further, the number of explosions per revolution of this engine can be achieved multiple times by making the above angle range relatively large and devising the shape of the combustion chamber and various valve timings.

Generally speaking, when an explosion occurs in the combustion chamber of a diesel engine, the entire engine must be made rigid due to the high explosion pressure, but with the device of this invention, only the output unit or compressor can withstand rotation. Since the strength is sufficient, the structure is weaker than that of conventional engines, and its weight can be reduced to a fraction of that of an engine with the same output.

Moreover, since the combustion chamber is separated from the rotating parts, the explosion pressure in the combustion chamber is limited to the combustion chamber, and the compressor
It does not reach directly to the output device.

In particular, due to the structural characteristics of this power unit, it is easy to manufacture and has the advantages of high mechanical efficiency, weight efficiency, and volumetric efficiency.

The structure of the fluid motor of the present invention is completely different from that of a conventional fluid motor.

In other words, the shaft is fixed and the case rotates,
With such a structure, it is possible to reduce friction between parts and obtain high rotational force.

The present invention will be described in detail below with reference to the accompanying drawings.

In the figure, FIG. 1 shows a cross section of the compressor V in the lower stage.

In this example, an air intake port 1a and compression ratio adjustment valves 1b and 1b' are formed on the circumference of the compressor-side cylinder 1.

FIG. 2 shows a cross section of the output device U located in the upper stage.

A high-pressure gas induction valve 2a and a gas exhaust port 2b are provided around the illustrated output machine side cylinder 2, and the two cylinders 1 and 2 share the same operating axis P passing through the same center point.
The rotating rods 3 and 3' are fixed to the operating shaft P with an angular difference of 180 degrees from each other, and rotate in the same direction inside the cylinders 1 and 2, respectively.

Inside these two cylinders 1 and 2, there is a cylinder center point [
An output machine side rotor 4' and a compressor side rotor 4, which rotate around an eccentric point O with respect to the center point of the operating shaft P, are provided separately, and two rotary blades, that is, blade members 3a, 3a, are provided separately. 'is cylinder side hinge pin 3ct3c'
and are connected separately by rotating rods 3b and 3b',
Both are connected so that they face in opposite directions in terms of their positional relationship.

Therefore, if the operating shaft P is moved in the direction of arrow A, the compressor ■
As a result, the air in the compression chamber W is compressed, and the compressed air passes through the suction valve 5a and enters the space of a certain combustion chamber 5 located in the middle of the flow path 20 formed by a suitable tubular member.

At this time, if fuel is injected from 5c, explosive combustion will occur, and this high-pressure gas will flow out to the gas expansion chamber Z side in the output machine through the exhaust valve 5b, and most of the high-pressure gas in the expansion chamber Z will be The gas flows into the gas storage tank 7 through the outlet H of the induction valve 2a, but does not flow back.

At that time, the high-pressure gas induction valve 2a works so that only the gas at the required pressure is selected by, for example, adjusting the timing of the valve 2a, and flows into the tank, and the remaining gas acts on the rotary vane 3a' of the output unit U. This provides power to rotate the rotary rod 3' while compressing the air in the space W of the compressor.

In this embodiment, the suction volume of the compressor (2) is fixed, but the amount of air compressed into the combustion chamber can be adjusted by the action of the compressor control valves 1b and 1b'.

That is, air other than the required amount is discharged to the outside through valves 1b and 1b', and the compression ratio within the combustion chamber is adjusted over a wide range.

In addition, when installing two rotating rods 3 and 3' each in order to increase the output, one of the two rotating rods should not be fixed on the operating axis P but can rotate freely around that axis (the seventh (Fig.), the generated rotational force is applied to the cylinders 4, 4' and can be indirectly transmitted to the operating shaft P.

Figures 4 and 5 show cross-sections of the air motor.

FIG. 6 shows an external view of the valve shaft E of the fluid motor.

This shaft operates in the state of contact between the outer cylinder 11 and the inner valve cylinder 9 shown in FIG. 4, but the shaft itself is fixed and does not rotate.

The outer cylinder 11 rotates around point T, and the valve cylinder 9 rotates around point Q.
Point Q is eccentric with respect to point T.

The connecting rod F connects the cylinder 9 while separating the space S and the space J of the external cylinder 11, and moves in the same direction as the cylinder 11 and the cylinder 9 during rotation.The valve axis E is shown in perspective as shown in FIG. As shown in the figure, the left end support shaft 14 and the right end support shaft 15 communicate with holes M' and K' formed like pipes inside the valve groove 8, respectively.
a t 8 b is installed outside the circumference around the eccentric point Q.

Further, holes C and D are provided in the valve cylinder 9 so as to match the valve grooves 8a and 8b.

When high-pressure gas is allowed to flow into the inlet K side of the right end support shaft 15 provided on the valve shaft E, the gas reaches the valve groove 8b through the hole K', and then flows into the hole C provided on the valve cylinder 9.
Go out to the side and press the connecting rod F to move the cylinder 11 and valve cylinder 9 to L.
direction.

The air in this space-time J passes through the hole D, the valve groove 8a, and exits to the shaft left end inlet M side and is discharged to the outside (FIG. 4).

On the other hand, if high pressure gas is allowed to flow into the M side, the gas will pass through the valve groove 8a and the hole D, push the connecting rod F from the space J, and act to rotate the cylinders 11 and 9 in the R direction.

In this case, the air in the space S passes through the hole C and the valve groove 8b, exits to the shaft right end inlet K side, and is discharged to the outside (FIG. 5).

In the fluid motor of the present invention, the cylinders 11 and 9 connected by the connecting rod F undergo a relatively large volume change during each rotation, but their operation interval is similar to that of a general piston engine.
Also, compared to other rotary engines, it is relatively grippy and has very few friction parts.

Therefore, it has advantageous advantages in terms of airtightness and wear, resulting in an extended life, simple structure, easy manufacture, and can be obtained at low cost.
