Abstract:
1. A valve combining a metering function and a pressure regulating function comprising: a valve housing to house a metering valve, said metering valve being movable by a control to meter an amount of fluid delivered from an inlet to an outlet; a pressure regulating valve being moveable relative to said metering valve, said pressure regulating valve being received within the valve housing and being supplied with a pressure delivered into said inlet on a first face, and a pressure downstream of said outlet on a second face, and said pressure regulating valve acting to regulate a pressure difference between the inlet and outlet; said control including an electronic control for selectively moving the metering valve; said electronic control controlling a difference in pressure of fluid at opposed sides of said metering valve; said pressure regulating valve being slidable along a portion of said metering valve, such that said pressure regulating valve and said metering valve move along coaxial axes; wherein said metering valve has a first enlarged land which meters the flow of a fluid from the inlet through the outlet; and wherein said pressure regulating valve controls an amount of fluid that is delivered from the inlet to a second outlet leading to a bypass line.
