POSITIVE DISPLACEMENT ROTARY MACHINE Russian patent published in 2002 - IPC

FIELD: mechanical engineering; internal combustion engines, pumps, compressors and other positive displacement machines. SUBSTANCE: proposed positive displacement rotary machine with swinging blades consists of two coaxial rotors with two opposite blades. Each rotor is coupled with uniformly rotating shaft by means of pair of Hooke's joints. Axes of first coupling member and coupling members of joints of intermediate links-rings are turned into perpendicular planes and they intersect in one point. Rings installed with tilting provide irregular rotation of rotors in antiphase. Intermediate links-rings are installed on rockers with axes of joints perpendicular to axis of drive shaft and intersecting the axis in point of intersection of joint axes. Rockers are furnished with tilting mechanisms for changing angular position of ring. EFFECT: enlarged operating capabilities of machines of machine owing to provision of change in compression ratio of internal combustion engine, capacity of pump and compressor in process of operation. 3 dwg
