FIELD: engines and pumps.
SUBSTANCE: device comprises a hydraulic pump 3 connected by its output to a hydraulic distributor unit 5, in its turn the hydraulic distributor unit 5 connected to inputs and outputs of hydraulic transformers 1 and 2 through the lines of high, increased and low pressure. In hydraulic transformers 1, 2 sensors 8 and 9 are connected to a control unit 7, respectively. The output of hydraulic stabiliser 4 is suitable to the high-pressure line connected by its input to compressed gas cylinder 6.
EFFECT: increased operation stability in both closed and open hydraulic systems, reduced level of hydraulic liquid pulsations with expanded range of delivered pressure.
