ROTARY-VANE ENGINE Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: engine has stator accommodating rotor with radial slots with fitted in vanes whose ends engage with inner surface of stator. Through radial slots pass through center rotation of rotor and n vanes are fitted in slots where n=1,2,3.... Vanes are U-shaped being fitted one into the other by U-shaped slots for displacement relative to each other. Inner surface of stator is section square to axis of rotation of rotor is made ellipsoidal providing non-equal volume-chambers between stator surface, rotor surface and vanes. Lengths of vanes passing through axis of rotation of rotor are equal to each other. EFFECT: enhanced reliability, simplified design of engine. 2 dwg
