FIELD: hydraulic systems. ^ SUBSTANCE: invention is designed to control hydraulic drive. Proposed unit contains high-pressure joint, low-pressure joint and two working joints, hydraulic distributor with shutoff element between supply connecting element and working connecting element, compensating valve arranged between high-pressure joint and hydraulic distributor which is in direction of closing under action of pressure between compensating valve and hydraulic distributor. Compensating valve in direction of opening is exposed to action of pressure from switching device which selectively delivers to compensating valve either pressure to adjust pressure or pressure to adjust flow rate. ^ EFFECT: optimization of power consumption. ^ 15 cl, 11 dwg |
