TWO-STROKE MULTICYLINDER ROTARY-PISTON ENGINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; engines. SUBSTANCE: engine housing is made in form of cylindrical flat split box with cylinders uniformly spaced over box outer surface. Cylinders have pistons and twin rods connected by cross links. Two different-size bearings are fitted on end of each link. Bearings are installed for rolling, each on one side wall of two-step slot made on both inner end face walls of housing. Antifriction bearing is installed on link of each cylinder along its axis. Antifriction bearing engages with outer surface of multicam rotor installed on shaft coaxially with housing. Links of rods of each pair of cylinders arranged at opposite sides of housing on one diametrical axis are connected by tie-rod for adjusting the length by means of frame and adjusting members connecting their free ends. Adjusting members are installed with clearance relative to diameter of rotor shaft. Frames of all pairs of cylinders are spaced over rotor shaft length to provide unobstructed reciprocating. Axes of each pair of opposite pistons, rods, links and tie-rods are arranged in one diametric axial plane. EFFECT: enlarged operating capabilities. 2 cl, 3 dwg
