ROTARY HYDRAULIC MACHINE Russian patent published in 2013 - IPC F04C2/08 F04C2/324 

FIELD: machine building.

SUBSTANCE: rotary hydraulic machine includes housing 1, epicyclic wheel 2 with internal teeth, sun wheel 3 with external teeth, which is fixed by means of hinges on the housing, a pair of similar floating satellites 6, interacting with epicyclic and sun wheels, as well as end cover plates with flat working surfaces, which are fixed relative to the housing, in which inlet 17 and outlet 18 openings are made. Epicyclic wheel 2 interacts with housing 1 by means of a drive piece, for example slide 19, which deprives epicyclic wheel 2 of the possibility of rotation relative to housing 1, and directly contacts housing 1, thus forming together with it a kinematic pair of higher degree of force closure, for the implementation of which the hydraulic machine is equipped with pressure device - spring 11.

EFFECT: increasing the productivity and specific power of hydraulic machine owing to increasing useful capacity; increasing its operating life due to automatic wear compensation of interacting surfaces.
