ABSTRACT:
A hydraulic control system for simultaneously driving two hydraulic loads of a production machine by means of a variable delivery pump feeding drive fluid to the two loads through separate load lines, in accordance with independently controllable programs of flow rate and pressure, the two load lines being controlled by two proportional P/Q valves, the pump being continuously adjusted for a constant pressure gradient in the load line which carries the higher pressure, the other load line having a pressure imbalance compensating device in the form of either a flow rate measuring device, a pressure balancing valve, or a displacement-to-voltage converter connected to the associated load.
