ROTOR INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: engine has hollow case provided with side covers, rotor provided with side covers, gas piston and oil seal and mounted within the case space, systems for gas distribution, fuel and air supplying, and systems for cooling, lubricating and starting. The piston is made of a plate pivotally connected to a pin by its one end, rigidly secured within the rotor on surface of the working chamber made of a sector with an arc end having radius which is equal to radius of the piston from axis of the pin to end of its radial seals mounted on the second end. The gas distributing system has ports for intaking air and discharging exhaust gases. The engine is provided additionally with supercharger, pump-nozzles, slide block and bearing axle. The bearing axle is rigidly secured to the side cover of the case eccentrically to the axis of the rotor. The piston is provided with a through groove which does not extend up to its end provided with the seals. The side cover of the rotor is provided with an axial opening conjugated with the surface of the side cover of the case. The bearing axle, which is kinematically connected with the through groove of the piston via the slide block, is received in the opening. The ports for intaking air and discharging exhaust gases are made in the side covers of the rotor and the case for their coincident. The pump- nozzles are positioned on the surface of this side of the rotor. EFFECT: enhanced efficiency. 8 dwg
