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

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to rotary internal combustion engines with variable speed of rotation of working members. Proposed engine contains housing with cylindrical working space, two coaxial working shafts, one nest in the other, to some end faces of which disks are connected with diametrically arranged sector vanes rotating in working space of housing. Driving gears of differential with output shaft of engine are connected to other end faces of working shafts. According to invention, engine contains twin Maltese-cross movement, one cross of movement being turned relative to other through half of angle of Maltese cross, and differential transforms rotary movement of working shafts into constant angular velocity rotation of engine output shaft. EFFECT: improved efficiency of engine. 2 dwg
