ROTARY-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2011 - IPC F02B55/02 F01C19/04 

FIELD: engines and pumps.

SUBSTANCE: rotary-piston internal combustion engine includes housing with operating ring having cylindrical surface the axes of which are offset. Rotating rotors are installed in working chambers parallel to the shaft. The first rotor acts as rotor of compressor and is made in the form of disc with spring-loaded operating gate valve. The second rotor acts as turbine rotor and is made in the form of shell with the end rigidly fixed on the shaft. Housing of combustion chamber has inlet window of working mixture and outlet window and is arranged in the hole of the widest part of operating ring. Engine is equipped with gas-distributing shell and L-shaped spring-loaded operating gate valve installed in swell of the second rotor. Gas-distributing shell interacts with combustion chamber and has shaft rigidly attached to its bottom and connected to engine shaft and is equipped with bypass window. Sealing segment of the first rotor, which is located on inner cylindrical surface of working ring under combustion chamber, and sealing segment of the second rotor, which is located on outer cylindrical surface of working ring above combustion chamber, are introduced to the engine. Sealing segments are of variable thickness. Back pressure channel, which is bent through 180°, is made inside sealing segment of the first rotor. Back pressure channels bent through 180° are made inside sealing segment of the second rotor on both sides.

EFFECT: higher operating efficiency and reliability, and simpler design of engine.
