HYDRAULIC MACHINE Russian patent published in 2013 - IPC F04C2/14 

FIELD: engines and pumps.

SUBSTANCE: hydraulic machine includes housing 1 with end cover plates 2, cylindrical rotor 3 and longitudinal shafts-satellites 7, which are arranged on end cover plates 2, and longitudinal partition walls 6 arranged on cylindrical surface of rotor 3. In shafts-satellites 7 there are longitudinal slots 8 for arrangement of partition walls 6 at synchronous rotation of rotor 3 and shafts-satellites 7. Channels 9 and 10 for supply and discharge of working fluid are made in housing 1. Cavities 15 are made in zone of working fluid supply channels 9 of housing 1 and elements 16 fixed on the housing are arranged, which are designed for formation of additional energy of rotational orbital movement of shafts-satellites 7 and rotor 3 under action of working fluid flow in a high pressure zone.

EFFECT: reduction of force of contact interaction of working parts of hydraulic motor and reduction of their mechanical wear.
