ABSTRACT:
A control arrangement for hydraulic drives for driving piston pumps includes a control piston which is switchable between its end positions. The control piston has reciprocably effective longitudinally-extending flow restrictors connected into the power lines of the hydraulic drive and the control valves corresponding to each flow restrictor are provided with a pressure balancer. The direction of flow of the hydraulic fluid is the same through all flow restrictors in all switching positions of the control piston. The pressure balancer is controlled by the drop in pressure across the flow restrictor corresponding thereto. The outlet of the control valve for the hydraulic fluid flowing to the hydraulic drive and the inlet for the hydraulic fluid flowing away from the hydraulic drive are connected together at a common connecting terminal of the hydraulic drive.
