HYDRAULIC DEVICE Russian patent published in 2010 - IPC F01C1/10 

FIELD: machine building.

SUBSTANCE: proposed device comprises gerotor assembly 30 with stator 31 and rotor 32 with interacting teeth that form gerotor chambers, manifold 40 with channels 55, 56 communicated with gerotor chambers and pressure equalising mechanism 60 that makes pressure chamber 65 and chamber of selective valve 70 communicated with said pressure chamber. Said chamber of selective valve 70 has first bore communicated with hydraulic system first bore 51 and second bore communicated with hydraulic system second bore 52, and ball arranged the chamber of selective valve 70. Said ball moves in the chamber of selective valve to seal one o the bores on feeding pressure in pressure chamber and compensate pressure in the device.

EFFECT: higher efficiency of engine operation due to displacement of planetary rotor to manifold.
