Control Device For A Hydraulic Differential

A control device for a hydraulic differential containing two hydraulic loops integrated within the common driving unit of the hydraulic differential control and having a distributor embodied as a common gate mechanism, where each of the loops includes two main collectors of toroidal configuration, and control branches with electromagnetically actuating of their control elements, wherein the gate of the main distributor is a rotating body in a form of a cylinder having an axial opening where at equal distances from the ends of the cylinder two identical discs thinned towards their periphery are formed, with the gate symmetrical with respect to a plane crossing perpendicularly the middle of its longitudinal axis, and with an interior of the body of the main distributor having the same parameters of symmetry and configured so that only in a neutral position of the gate at both sides of each disc are formed separate chambers insulated from each other, where the chambers at each side of the gate are connected with areas of high and low pressure in separate hydraulic loops, so that the pressures of both loops have opposite directions to the discs of the gate along its longitudinal axis, and the cross point of the longitudinal axis of the gate and its transverse plane of symmetry lies on the side of the rotating axis of the differential which crosses its common driving unit.
