ROTARY COMPRESSION MACHINE Russian patent published in 1999 - IPC

FIELD: mechanical engineering; volumetric expansion rotary machines. SUBSTANCE: machine has housing-stator with spherical working space and rotor with spherical boss, separating disk with radially arranged blades and two cups-inserts mated with spherical surfaces of working space and rotor boss. Rotor consists of two axle-shafts arranged at angle. Spherical boss and separating disk are made on one of axle-shafts, and cups-inserts, on the other axle-shaft. Separating disk has radial axles with slots, and cups-inserts are rigidly interconnected by radial blades mated with slots on disk radial axles. EFFECT: increased reliability and efficiency of machine, reduced weight, provision of compactness. 2 dwg
