ABSTRACT:
In an hydraulic generator-receiver for power transmission, with an improved hydraulic balancing, balancing of the axial force of the driving gear is effected by varying the value of the surface of the permanent high pressure zone, so that this variation causes an application of the high pressure on a surface of one of the side plates, either greater, or lower, while the value of the permanent high pressure zone has no influence on the other side plate. In addition, the inter-sector zone is incorporated in the sectors of the envelope to balance the tangential force of the driving gear.
