HYDROTRANSMISSION Russian patent published in 2015 - IPC F16H39/06 F04C2/00 

FIELD: engines and pumps.

SUBSTANCE: claimed transmission comprises the housing closed by the front and rear covers, vaned pump with shaft extending to the rear cover bore, oil tank, forward and reverse gear changing plug, pipes communicating all assemblies, control mechanisms articulated with the fluid valves. Hydromotor each vane has two vertical chambers. The latter feature the identical design and are turned in horizontal plane relative to each other through 180 degrees, isolated from each other and composed of horizontal, vertical and inclined surfaces. Said chambers are closed by lateral covers with fluid inlets provided with transverses teeth shaped to equilateral triangles with their bases facing the inner surfaces of the covers. Fluid pressure to inner surfaces of said chambers are equalised. Additional surfaces for fluid pressure to act on are the read walls of the chambers.

EFFECT: higher power output, power saving.
