Abstract
Embodiments of the invention provide a control valve including a control valve body having an inlet passage, an outlet passage, a workport, and a chamber arranged in a fluid path between the workport and the outlet passage. The control valve further includes an annular poppet slidably received within the chamber and to selectively engage a poppet seat to inhibit fluid flow through the fluid path when a pressure in the fluid path is less than a predefined pressure level, and a valve element slidably received within the control valve body to selectively provide fluid communication between the inlet passage and the workport and selectively provide fluid communication between the workport and the outlet passage along the fluid path. The poppet is biased towards the poppet seat by an elastic element.
