The valve has a valve housing (20) comprising a valve chamber with an intake opening (10) and an outlet opening (11). A movable piston (22) has an axial connection channel (14) and axially guided by sealing elements (41, 42). An effective piston surface (A1) faces an inlet area (17) of the chamber. A sealing body (21) forms a valve seat. The piston is axially moved by changing pressure in a storage area (19) of the chamber. A passage opening (13) is reversibly closed and opened, arranged between the intake and outlet openings and held open by a spring (23) in an unpressurized state. |
