ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed engine has stator, rotor with sealing plates engaging with projections and cavities on inner profile surface of stator and forming, together with face covers of stator, surface of rotor and profiled surface of stator, working chambers with intake and delivery zones, working chambers of fuel mixture intake-ignition with zone of additional compression and exhaust gases expansion and discharge chambers. According to invention clearance made between projections of stator profiled surface and rotor serves to pass compressed air from additional compression zone in which rarefaction is built to deliver fuel. Sealing plates on ends adjoining inner profiled surface of stator are provided with articulated movable seals. Sealing plates are provided with through cross cut ensuring movability of plates lengthwisely. EFFECT: improved efficiency of engine operation. 2 cl, 4 dwg
