Abstract:
A pump arrangement and method of regulating pressure of a pump arrangement are provided. The pump arrangement includes an actuation pump, a pressure regulating valve, and a control valve. The actuation pump has an actuation pump outlet providing an actuation pump discharge flow. The actuation pump discharge flow is piped to opposite sides of a regulator valve member that selectively adjusts an amount of fluid that is bled from the actuation pump outlet such that the actuation pump outlet pressure is used to regulate the actuation pump discharge pressure. The actuation pump discharge flow is separated into first and second portions to provide opposing forces on the regulator valve member. The control valve is operably interposed between the actuation pump outlet and the valve member to selectively adjusts the amount of biasing applied by the second portion of the actuation pump discharge flow on the regulator valve member.
