ROTARY PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2018 - IPC F01C19/08 F02B55/02 

FIELD: engines and pumps.

SUBSTANCE: invention relates to the engine building. Essence of the invention consists in that the engine comprises a housing with a working ring, working chambers in whose cavities a compressor rotor is mounted, made in the form of a disk with a projection on its outer cylindrical surface, and a rotor of the turbine, made in the form of a glass with a rigidly fixed on the shaft bottom, a combustion chamber, a gas distribution cup, a spring-loaded working flap of the compressor rotor, L-shaped spring-loaded damper of the turbine rotor, external and internal side cheeks, between which inside the working ring is built the compressor rotor, spark plug. Inside the working ring there is a sealing device made in the form of an elastic disc with a central hole pressed against the inner surface of the working ring with the possibility of moving in the working ring as parallel to the axis of the motor shaft by means of a screw-nut pair having a left thread and circumferentially by a spring. Nut of the screw pair is rigidly connected to the elastic disk. Screw is connected to the outer side cheek of the engine. One end of the spring is bounded by a protrusion on the nut of the screw pair, and the second end of the spring is limited by a projection on the outer side cheek of the engine. Rotor of the compressor is movable along the motor shaft and is provided with beads located on its lateral surfaces along the outer diameter and adjacent to the inner side cheek on one side and on the other side to the elastic disk.

EFFECT: technical result is to increase the efficiency of the engine by improving the sealing of working volumes.
