ABSTRACT:
The distributing device of a vehicle hydraulic control system comprises a distributor connected via hydraulic lines to a servomotor, a pump and a tank, the control member of the distributor being mechanically connected with the steering drive shaft, and further includes a hydraulic machine connected via hydraulic lines with the hydraulic distributor, the rotary member of this machine being adapted to vary the volume of the working chambers and being mechanically connected with the actuating member of the hydraulic distributor and with the steering drive shaft, the steering drive shaft being rotatable relative to the rotary member of the hydraulic machine within an angular play value providing for the preset displacement of the control member of the hydraulic distributor. The hydraulic machine has two cylinder blocks with respective pistons, wherein the cylinders are arranged circumferentially in opposing pairs, the working chambers of the opposingly arranged cylinders communicating with each other and communicating with the hydraulic distributor, the rotary member of the hydraulic machine being arranged between the cylinder blocks and including a disc with profile cams provided on its opposite end face surfaces, the cams being arranged in opposing pairs for cooperation with the respective pistons.
