ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 1998 - IPC

FIELD: transport engineering; ground and air vehicles. SUBSTANCE: cylinders 3 are made in cylindrical rotor 2 of engine along its axis. Twin pistons 4 made integral with slider 5 or rigidly connected with slider are arranged in cylinders. Cylindrical ring 8 of rotor is freely fitted on rotor. Sets of sealing plates 20 are installed on radial surface of rotor close to cylinder holes. Sealing plates 20 are in contact with cylindrical ring of rotor through flats. Power takeoff shaft 7 with eccentric is coupled with synchronizing internal gears, gear ratio being 2:1. Larger internal gear is rigidly secured on cylindrical rotor and smaller internal gear is made integral with power takeoff shaft. Planetary movement of pistons 4 with slider 5 is provided in engine and appearance of alternating inertia forces is prevented. Fuel-scavenging and exhaust channels are made in cylinders. Scavenging-cooling port is made on front end face cover and nozzle is installed. Exhaust port is made in rear end face cover. EFFECT: enlarged operating capabilities. 2 dwg
