AXIAL INTERNAL COMBUSTION ENGINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; internal combustion engines for automobiles, tractors, vessels and generator drives. SUBSTANCE: power mechanism of engine converting reciprocating motion of pistons into rotary motion of central shaft has flywheel with multiple period two side screw-and-arc profile projection made on outer cylindrical surface of flywheel. Profile at right and left end faces of this projection in axial direction is formed by convex and concave arcs of circumference. Race chutes are made on clockwise and counterclockwise surfaces. Rollers of crosshead straddle flywheel projection by their outer spherical surfaces and engage with races. EFFECT: simplified design, improved reliability, increased effective power owing to reduction of mechanical losses. 14 cl, 12 dwg, 1 tbl
