INTERNAL COMBUSTION ROTARY-VANE ENGINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; rotary-vane engines. SUBSTANCE: proposed rotary-vane engine contains housing, two rotors with two vanes and hub, each, forming combustion chamber with ignition device. According to invention two movable stops are installed on housing to limit rotation of rotors in direction of movement of output shaft, and two movable stops limiting rotation of rotors in direction opposite to movement of output shaft. Clutches are provided on rotor hubs for connecting rotors with output shaft at definite positions of vanes relative to housing. Stops preventing rotation of rotors in direction of movement of output shaft can be made with possibility of moving off by pressure of gases formed at combustion of fuel and getting out of combustion chamber. EFFECT: improved efficiency in operation. 6 cl, 11 dwg
