ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 2010 - IPC F02B55/02 F01C1/38 F01C17/04 

FIELD: engines and pumps.

SUBSTANCE: rotor internal combustion engine consists of fixed housing with inner curvilinear close surface, intake and discharge openings and rotor. Rotor is fitted on the shaft and represents a frame with pistons in constant contact with rotor frame and housing curvilinear surface. Variable-volume chambers are arranged between the housing inner curvilinear surface and piston surfaces. Said inner surface is formed by arcs of different-radius conjugated circles. Additionally, said housing gas sectors, bearings and end sealing covers. One of said end sealing covers supports cage with the shape representing an inner curvilinear closed surface of the housing. Piston travel control links are attached to aforesaid sectors. Bearings are arranged in rotor frame to hold and move said sectors. Pistons are attached to sectors and stay in constant contact with cage surface. Gears are fitted on rotor shaft and sectors to interact thereon.

EFFECT: longer life and elimination of engine vibrations.
