On the air compressing device, the volume of a first space between adjacent blades is sucked in the process of changing from small to large, and then the air is compressed in the process of changing from large to small. On the acting device, the process that the volume of the second space between the adjacent blades is changed from small to large does work, and the process that the volume of the second space between the adjacent blades is changed from large to small is utilized to discharge waste gas.

When the gas is pressed to the minimum in the air compressing device, the compressed air is pressed into the work doing membrane block through the communicating pipe and is mixed with the sprayed fuel to form a high-pressure working medium, and the work doing cavity of the work doing machine is filled with the high-pressure working medium and rotates to a phase which is most beneficial to 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 simultaneously 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, the stressed blades push the second roller to rotate by utilizing the lever principle, and then other blades are driven to rotate, and 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 work is done, the volume between the adjacent blades of the work doing cavity begins to be reduced, and 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 blade of the rotor of the air compressing device to rotate, the fixed blade of the air compressing device drives the first roller to rotate, the first roller drives the swing blade to rotate, the adjacent blades suck air in the process that the volume is changed from small to large among the blades, 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 and air compression working and air exhaust are all carried out in the same container with fixed volume, the expanded hot air can not fully work and is discharged as waste gas to waste partial heat energy, so the heat efficiency is not high. The complex connecting rod crankshaft mechanism and the intake and exhaust valve control mechanism also lead the structure of the whole machine to be complex, heavy and high in cost, and the crankshaft rotates for 4 strokes of the piston for two circles to do work once, thus leading to low power-weight ratio, heavy weight, high output power and low rotating speed. The process of converting from linear motion to rotary motion also introduces vibration and noise.

The existing gas turbine internal combustion engine adopts an axial flow type coaxial rotor structure, an air compressing blade and a working blade share a straight shaft, the blades and a main shaft form a certain included angle, the kinetic energy air compressing mode of an axial flow type turbine compressor and a centrifugal turbine compressor is adopted to compress air, the compressed air is mixed with fuel and then ignited to expand to work, the working machine adopts an axial flow type turbine, high-pressure hot gas flows along the axial direction to act on the turbine blades, and the circumferential component force pushes the turbine blades to rotate. The exhaust gas is directly ejected in the axial direction. Simple structure, high power-weight ratio, high rotation speed and low noise. The efficiency of compressing air is high when the engine is operated at high speed, so the thermal efficiency is higher than that of a reciprocating piston engine.

Because the kinetic energy compression mode of axial flow type compression and centrifugal type compression is adopted, the air can be compressed to the ideal air pressure only at high rotating speed, so that the high combustion efficiency is achieved, the air can not work in a high-power working area of high compression, and the air can not work at low rotating speed and idling, so that the axial flow type gas turbine internal combustion engine can not be suitable for occasions of medium and low power and rotating speed such as civil transportation tools. The high-temperature, high-pressure and high-speed working environment limits the manufacturing process requirements of the blade, so that the manufacturing cost is extremely high.

In this application, will do work cavity and pressure cavity fall into the cavity of variation in size through fixed blade and swing blade, improve in the heat engine efficiency by a wide margin, from lighting to the inflation exhaust process, the volume expansion ratio is enough big, does not have linear motion conversion circular motion's loss, also does not have the extra friction loss that the eccentric vibrations of bent axle brought, and the burning steam does work the stroke big, and the pump gas loss is little, can increase substantially heat engine efficiency.

This application will do work cavity and pressure cavity divide into the cavity of variation in size through fixed blade and swing blade, adopts the volume of becoming mode compressed air that calms the anger, does not receive the rotational speed restriction, under well low rotational speed and idle operating mode, equally can reach the compression ratio of ideal, satisfies the demand of high-efficient burning.

The rotor of the acting device and the rotor of the compression device are in the rotating process, in the acting or compression process, except for 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 reduced by the size, the compression ratio is improved, and the acting efficiency and the compression efficiency can be improved.

In addition, the structure of the engine does not have gears and crankshafts to do work, and the engine is simple in structure like an axial-flow turbine internal combustion engine, so that the rotating speed is high, and the output torque is high.

The noise of the reciprocating internal combustion engine is low, the impact noise of a connecting rod to a crankshaft is avoided, the vibration noise of eccentric rotation is avoided, the noise of gear meshing is avoided, the structure is simple, the axial-flow internal combustion engine is similar to the axial-flow internal combustion engine with the same size in weight, the volume and the weight are extremely light, the manufacturing cost is far lower than that of a reciprocating internal combustion engine with a complex structure, the working conditions of a rotor blade and a roller barrel are better than that of the axial-flow internal combustion engine, and the manufacturing cost is far lower than that of the axial-flow internal combustion engine.

The air compressing device realizes the compression of air only through the circular motion of the first fixed blade, the first swing blade and the first roller, and the whole process has no conversion of other motions, so that the energy loss caused by the conversion is correspondingly reduced; the acting device realizes power output only through the circular motion of the second fixed blade, the second swing blade, the second roller and the second main shaft, and the whole process has no corresponding conversion of other motions, so that the problem of waste of heat energy of the internal combustion engine can be solved, the heat conversion efficiency is improved, and the working device has good practical value.
