Abstract
A valve, preferably of the flow control construction type, has a valve piston or pressure regulator piston mounted in an axially displaceable manner in a valve housing. The valve piston and the valve housing form a damping chamber for the motional damping of the valve piston.
Claims11
A valve, comprising:
- a valve housing;
- a pressure regulator piston mounted in an axially displaceable manner in said valve housing and having a first axial end portion;
- and
- an axial end plate fixed in the valve housing and having a central bore through which the pressure regulator piston is axially guided;
- a substantially enclosed damping chamber defined by the axial end portion of the pressure regulator piston, the valve housing, and the axial end plate, the damping chamber being configured to damp axial motion of the pressure regulator piston;
- and
- a restriction nozzle configured to restrict flow of a fluid into and out from the damping chamber to damp the axial motion of the pressure regulator piston.
