GEAR HYDRAULIC UNIT Russian patent published in 2012 - IPC F04C2/08 

FIELD: hydraulic machine.

SUBSTANCE: invention refers to hydraulic positive displacement machines. Gear hydraulic machine has body 1, stable epicyclic ring 2 with internal teeth, driving crank 3, sun ring 4 with external teeth, located on the balls on the crank 3, two flowing satellites 5 and 6, the axis of which are located lineary in the initial position of the hydraulic machine. The axis of satellites coinside with axis C og epicyclic and B of the sun rings 2 and 4, end caps fixed on the body 1, channles 8 and 9 to feed and discharge operating media made in the body 1 or cap of hydraulic machine. Axis V of the ball connecting crank 3 and sun ring 4 is located inside the initial circle of sun ring 4 and displaced in respect to central axis B of sun ring 4 to the distance 1.2-2 more than the length of crank 3.

EFFECT: invention increases capacity and service life of pump mechanisms and compressors.
