ROTARY-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2019 - IPC F01C1/356 F02B55/02 F02B53/08 

FIELD: machine building.

SUBSTANCE: invention relates to propulsion engineering, particularly, to rotary-piston internal combustion engines. Proposed engine comprises housing with compressor and turbine rotors composed of parallel disks fitted on shaft. Radial groove of compressor rotor on surface of compressor rotor, which is opposite to surface of turbine rotor, and radial slot of turbine rotor on surface of turbine rotor on opposite side from flywheel are made with depth, smoothly increasing from zero to maximum value at first quarter of arc of circle of each rotor and smoothly decreasing from maximum value to zero value at second quarter of arc of circumference of each rotor. Slots in rotors are offset relative to each other by 180°. Rotor of the turbine has outer diameter equal to the outer diameter of the compressor rotor. In the engine housing there is a cartridge with spring-loaded dampers, which are installed in radial grooves of rotors of the compressor and turbine with possibility of movement relative to the cartridge body. In shutter of compressor rotor there is an opening and closing bypass channel, which connects compression chamber with combustion chamber, and in shutter of turbine rotor - opening and closing by its movement passage channel connecting combustion chamber with working stroke chamber. Combustion chamber is located in the case of the block of dampers between gates. Engine is additionally equipped with sealing elements of spring-loaded dampers, made in the form of transverse and longitudinal sealing plates, and sealing elements located between compressor rotor and housing and located between turbine rotor and housing, made in form of spring-loaded sealing rings.

EFFECT: technical result consists in higher engine efficiency.
