ROTARY-PISTON MACHINE Russian patent published in 1999 - IPC

FIELD: mechanical engineering; compressors, pumps, gas-expansion machines, engines. SUBSTANCE: each of pistons installed at least in two pairs of opposite cylinders is hinge connected, in center of mas by pin passing through longitudinal slots made in end face walls of cylinder block, with one of rotary tables whose axes of rotation are displaced relative to axis of cylinder block rotation through equal value in opposite sides for each pair of pistons. Pockets are made on opposite side surfaces of each piston in planes square to plane of rotation. Each pocket is connected with one of planes of longitudinal slot separated from each other by body of pin and formed by end face surface of rotary table and surface of piston. plane formed by intersection of opposite cylinders and end face surfaces of pistons is connected with liquid source exposed to gauge pressure. EFFECT: enhanced reliability and increased operating speed owing to dynamic balancing of all members of machine. 4 cl, 2 dwg
