ROTARY MACHINE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: stator ring is arranged in housing with profiled inner surface and end plates. Mounted concentrically on shaft in the ring is rotor with slots which receive separating plates for reciprocating and forming the precompressing chamber under plates and suction and discharge chambers in the ring. On the delivery side of the plate there are longitudinal bores. On the inner surface of the end plates there are circular grooves for communication with longitudinal bores. End plates have through holes which bring grooves in communication with interior of housing. Plates are arranged in rotor for bringing the discharge chambers in communication with working medium discharge passage by means of bores. EFFECT: enhanced reliability. 4 cl, 11 dwg
