ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to constant-volume combustion engines. Proposed engine contains shaft-mounted rotor with four force-taking semichambers at each side arranged in mirror- like manner relative to each other from opposite sides and stator in which corresponding semichambers are arranged at both sides from rotor opposite to its force-taking semichambers in form of alternating working and scavenging semichambers. Each working semichamber is connected with corresponding mixing semichamber by one channel directly and by other channel through ignition chamber connected to fuel-air mixture ignition unit. Inputs of each mixing chamber are connected to fuel and compressed air feed units, scavenging semichambers being connected to compressed air feed unit. EFFECT: improved reliability and increased efficiency of engine. 3 cl, 2 dwg
