HYDRAULIC POWER TRANSFER DEVICE Russian patent published in 2016 - IPC F01C1/10 F04C2/10 

FIELD: power engineering.

SUBSTANCE: invention relates to transfer of hydraulic power by fluid displacement with the help of trochoid gearing, particularly, to the reduction of friction in said gearing. Fluid power transfer device with trochoid gearing incorporates the coaxial hub with inner and/or outer rotor 40 and appropriate bearing assembly with rolling element and preloaded bearings 44, 46 for precise setting of rotational axis and/or axial position of the rotor 40 coupled therewith.

EFFECT: minimised fluid shifting force and/or leaks, ruled out gearing teeth wear, efficient sealing between chambers.
