ROTOR-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2015 - IPC F02B53/08 F01C19/08 

FIELD: engines and pumps.

SUBSTANCE: rotor-piston internal combustion engine comprises a body of an engine with a working ring being its part and working chambers formed by working cavities. In working cavities in parallel on a shaft there is a compressor rotor and a turbine rotor installed. The compressor rotor is built inside the working ring between side cheeks. Slots are made on the external surface of the compressor rotor. In the slots there are external and internal sealing rings. The external diameter of the rings is equal to the compressor rotor diameter. External sealing rings are installed as capable of displacement in parallel to the engine shaft and have flat surfaces at one side, which press to flat surfaces of the side cheeks, and have wedge-shaped surfaces at the opposite side sloped towards side cheeks. Internal sealing rings are installed with the possibility of radial movement and have at one side flat surfaces pressing to surfaces of compressor rotor slots, and at the other opposite side they have wedge-shaped surfaces sloped towards the opposite side from side cheeks at the same angle as wedge-shaped surfaces of external sealing rings. External sealing rings are equipped with ledges arranged inside holes of the compressor rotor.

EFFECT: increased capacity and cost-effectiveness of an engine.
