In this embodiment, the air compressing device a may be fixedly disposed with the acting module b, that is, the first stator 1 of the air compressing device a may be fixedly connected with the second stator 7 of the acting module b coaxially, the first spindle 201 of the air compressing device a is fixedly connected with the second spindle 802 of the acting module b, when the first spindle 201 of the air compressing device a is started, the motor may drive the first spindle 201 to rotate, after the acting module b is started, the first spindle 201 may be synchronously rotated under the drive of the second spindle 801, and at this time, the motor and the first spindle 201 may be disconnected.

On the air compressing device, the volume of the first space between the adjacent blades is sucked from a small to large changing process, and compressed air is reused from a large to small process. And on the acting device, the volume of the second space between the adjacent blades is smaller than Cheng work, and the waste gas is discharged by utilizing the process that the volume of the second space between the adjacent blades is larger than that of the second space between the adjacent blades.

When the gas is pressed to the minimum in the air compressing device, compressed air is pressed into the working membrane block through the communicating pipe and is mixed with the injected fuel to form a high-pressure working medium, and the working cavity of the working machine is filled with the high-pressure working medium and rotates to a phase position which is most favorable for ignition to ignite the working medium. The pressure of the combustion expansion of the working medium pushes the blades and the roller to move towards the direction of the blades with larger stress surfaces to do work, and the volume is changed from small to large. The expansion pressure generated by the expansion hot gas acts on the blades vertically along the circumferential direction to push the stressed blades to rotate around the shaft, and the stressed blades push the second roller to rotate by utilizing the lever principle so as to drive other blades to rotate, wherein the fixed blades drive the main shaft to rotate. The whole working process airflow flows along the circumferential direction in the working machine. After the working is finished, the volume between the adjacent blades of the working cavity starts to be reduced, and the waste gas is discharged in the process of reducing the volume.

In the working rotation process of the rotor of the working device, the main shaft drives the fixed blades of the rotor of the air compressing device to rotate, the fixed blades of the air compressing device drive the first roller to rotate, the first roller drives the swing blades to rotate, the adjacent blades suck air in the process that the volume between the blades is changed from small to large, the air is compressed in the process that the volume is changed from large to small, and the air flow in the compression process flows along the circumferential direction.

The existing reciprocating piston engine is composed of a cylinder, a piston, a connecting rod, a crankshaft, an intake valve and an exhaust valve. Because the four strokes of air suction, air compression, acting and air exhaust are all carried out in the same container with fixed volume, the expanded hot air can not fully do work and can be discharged as waste gas to waste part of heat energy, so that the heat efficiency is not high. The complex connecting rod crankshaft mechanism and the intake and exhaust valve control mechanism also lead the whole engine to have complex structure, heavy weight and high cost, and 4 strokes of the pistons rotate for two weeks to do work once, so that the power-weight ratio is low, the weight is large, the output power is small, and the rotating speed is low. The process of converting rectilinear motion into rotary motion also brings about vibration and noise.

The existing gas turbine internal combustion engine adopts an axial flow type coaxial rotor structure, a straight shaft is shared by a compressed air blade and a working blade, a certain included angle is formed between the blade and a main shaft, air is compressed in a kinetic energy air compressing mode of the axial flow type turbine compressor and a centrifugal type turbine compressor, the compressed air is mixed with fuel and then is ignited to expand to do work, the working machine adopts an axial flow type turbine, high-pressure hot air acts on the turbine blade along the axial direction, and a circumferential component force pushes the turbine blade to rotate. The exhaust gas is directly sprayed out along the axial direction. Simple structure, high power-weight ratio, high rotating speed and low noise. The compression efficiency is high during high-speed operation, so the thermal efficiency is also higher than that of the reciprocating piston engine.

Because the kinetic energy compression mode of axial flow compression and centrifugal compression is adopted, air can be compressed to ideal air pressure only at high rotation speed, the high combustion efficiency is achieved and the engine cannot work in a high-power working area with high compression and at low rotation speed and idle speed, so that the axial flow type gas turbine internal combustion engine cannot be suitable for the situations of medium and low power and rotation speed of civil transportation tools and the like. The high temperature, high pressure and high speed working environment is extremely high in manufacturing cost due to the fact that the requirements of the manufacturing process of the blade are met.

According to the application, the working cavity and the pressure cavity are divided into the cavities with different sizes by the fixed blade and the swinging blade, so that the efficiency of the heat engine is greatly improved, the volume expansion ratio is large enough in the process from ignition to expansion and exhaust, the loss of linear motion conversion circular motion is avoided, the additional friction loss caused by eccentric vibration of a crankshaft is avoided, the working stroke of combustion hot gas is large, the pumping loss is small, and the efficiency of the heat engine can be greatly improved.

According to the application, the working cavity and the pressure cavity are divided into the cavities with different sizes through the fixed blades and the swinging blades, the air is compressed by adopting a variable-volume air compressing mode, the air is not limited by the rotating speed, the ideal compression ratio can be achieved under the working conditions of medium and low rotating speeds and idle speed, and the requirement of efficient combustion is met.

In the rotating process of the rotor of the acting device and the compressing device, in addition to the volume change caused by the change of the distance between the outer wall of the roller and the inner wall of the stator, the included angle between the blades is also changed from large to small, the compression ratio is improved, and the acting efficiency and the compression efficiency are further improved.

In addition, the structure of the application does not have the participation of gears and crankshafts in doing work, and has the same simple structure as an axial-flow turbine internal combustion engine, so the rotating speed is high, and the output torque is high.

The application has low noise, no impact noise of the connecting rod to the crankshaft, no vibration noise of eccentric rotation, no gear meshing noise, simple structure, and the like, has the advantages of similar weight, relatively extremely light volume and weight, far lower manufacturing cost than a reciprocating internal combustion engine with complex structure, better working conditions of rotor blades and a roller body than the axial internal combustion engine, and far lower manufacturing cost than the axial internal combustion engine.

The air compressing device realizes compression of air only through the circular motions of the first fixed blade, the first swinging blade and the first roller, has no conversion of other motions in the whole process, and correspondingly reduces energy loss caused by conversion; the working device realizes power output only through the circular motions of the second fixed blade, the second swinging blade, the second roller and the second main shaft, and the whole process does not have corresponding conversion of other motions, so that the problem of heat energy waste of the internal combustion engine can be solved, the heat conversion efficiency is improved, and the working device has good practical value.
