ROTARY-PISTON MACHINE Russian patent published in 1998 - IPC

FIELD: power engineering; compressors, pumps, gas expansion machines, engines. SUBSTANCE: machine has housing, cover, bearings, support trunnion, cylinder block with opposed cylinders accommodating two equal mass pistons installed at equal distances from its center of rotation, eat each being hinge-connected in center of mass with one of two face plates. Axes of rotation of face plates are displaced through equal distance to diametrically opposite sides relative to axis of rotation of cylinder block. Machine has pin passing through longitudinal slots made on end face surfaces of cylinder block and provided with side clearances to ensure noncontact arrangement of piston in cylinder. Kinematic pair formed by longitudinal slot and pin, playing the part of movement synchronizer through which torque is conveyed from cylinder block to face plates, is used simultaneously as oil pump providing delivery of oil into cylinders in process of compression and delivery of gas. Face plates and cylinder block are in intimate contact through end face surface on which unloading pockets are made to provide preset specific contact pressures between these parts and also gas inlet and outlet holes, suction and delivery ports, and channels to feed oil to oil pumps. Hydrostatic pockets made on side surfaces of pistons are connected with oil pressure source. Delivery channels made in face plate body connect gas suction space with suction ports. EFFECT: enlarged operating capabilities. 7 cl, 6 dwg
