ROTOR INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: rotor internal combustion engine has case 1 provided with combustion chamber 18 and expansion chamber 17 separated by lateral wall 4 and members for forming and controlling interconnection between them. The chambers are formed with inner cylindrical surfaces of case 1 and cylindrical surfaces of rotors 10,9, which are set on common shaft 8, positioned eccentrically to them and contacting with them along generatrices. Rotor 10,9 are provided with radial grooves movably matted with radial vanes which are in contact with inner cylindrical surfaces of case 1. Chambers 18,17 are axially alined. The radial vanes are rigidly secured between circular lateral wall 4 and two additional circular lateral walls 3,5 mounted movably and coaxially to inner surface of case 1. Rotor 10,9 are positioned between the walls and are in contact with them, and rotor 10, which forms combustion chamber 18, is mounted for rotation relatively shaft 8 of the engine. EFFECT: simplified design and enhanced longevity of the engine. 4 dwg
