ABSTRACT:
A pump system including a control system for controlling a variable flow pump for controlling oil flow and oil pressure in a hydraulic circuit in an engine. The system includes a pump member, an actuating member capable of controlling the flow generated by the pump member, and a solenoid valve system including a solenoid valve portion and a pressure regulator valve portion. The solenoid valve system is operably associated with the pump and the pressure regulator valve portion is operably associated with the actuating member for selectively controlling the flow generated by the pump member. An electronic control unit is operably associated with the solenoid valve portion, wherein the electronic control unit is selectively operable to provide an input control signal to the solenoid valve portion for controlling oil flow and oil pressure.
