Abstract
A valve which may operate as either a check valve or a relief valve includes a chamber which is connected to a first hydraulic conduit by a restricted passage. A relief valve vents the chamber at a predetermined pressure to unbalance the valve member and allow fluid to flow from the first conduit to a second. The valve member is made with a telescoping portion to allow reverse flow when the first conduit is at a lower pressure than the second.
