POSITIVE DISPLACEMENT ROTOR-TYPE MACHINE WITH SEPARATE PASSAGES BETWEEN SPHERICAL WORKING CHAMBERS Russian patent published in 2009 - IPC F01C3/06 F04C3/06

Abstract RU 2375584 C1

FIELD: engines and pumps.

SUBSTANCE: invention relates to machine building, particularly to rotor-type positive-displacement machines, that can be used as pumps, compressors, hydraulic drives, flow metres of, for example multi-stage submerged units. Pressure sections of proposed machine feature passages for working body to flow from one working chamber into another. At least a part of one passage is arranged on the housing sphere-like surface.

EFFECT: higher efficiency and longer life.
