VANE FACE ENGINE Russian patent published in 1994 - IPC

FIELD: drilling wells. SUBSTANCE: stator is fixedly mounted in a case. A rotor provided with grooves is received in the stator forming working chambers. Vanes are received in the grooves for reciprocation and interaction with inner curved surface of the stator. The rotor is fitted on a shaft which is set in bearings. The rotor consists of separate members which are set on the shaft with slits. A face distributor arranged from the side of working fluid supply is made of a disk which is provided with profiled ports and a space bushing which encloses the disk. The disk and bushing are interconnected through pins. The distributor is pressed to the face surface of the rotor, is mounted for axial movement along the shaft axis, and has sections profile of which is the same as profile of inner surface of the stator providing their conjugation. Stator, vanes bearings, face distributors and rotor are made of enhanced rigidity and durable materials. EFFECT: enhanced efficiency. 3 dwg
