ROTOR-PLUNGER INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: engine has hollow housing with suction and exhaust passages and ports, rotors having at least two pistons, conical differential, supporting device with a controlling cam mechanism having bearing and controlling cams and rotatable stops mounted on the rotors, and output shaft with a flywheel. Satellites of the differential are positioned on the axle rigidly secured to the output shaft. The central conical wheels are rigidly connected to the corresponding rotors. The engine is also provided with dampers mounted on the rotors. The supporting device is provided with planet reduction gears and flexible members. Each bearing cam is set on the corresponding carrier of the reduction gear for permitting rotation and is coupled with it through flexible members. The controlling cams are rigidly secured to the housing. The corona wheel of the reduction gear is coupled with the shaft. The dampers are mounted on the rotors for allowing flexible contact at end mutual positions of the rotors. EFFECT: enhanced efficiency. 3 dwg
