ABSTRACT:
A system for controlling a discharge flow rate of a variable displacement pump within an oil hydraulic circuit is disclosed. A bypass with a flow restricting valve couples the pressure control chamber of the discharge flow rate controller to the tank line to thereby allow a part of the oil in the pressure control chamber to escape through the bypass to the tank line. This escape occurs when a highly pressured oil is rapidly injected into the pressure control chamber of the discharge flow rate controller as a result of switching operations of both the pressure compensated valve and the load sensing valve.
