摘要：
The valve includes a control piston axially slidable in a cylindrical bore which controls the cross-sectional area of an orifice of a connection between the cylindrical bore communicating with a pressure port and a user port. The control piston is acted on by a spring and a pressure which is reduced relative to the pressure at the pressure port. A cushioning arrangement acting on the control piston avoids occurrence of pressure surges affecting the control piston behavior.
