Abstract:
Control valve for flowable media, comprising an actuating piston which is arranged in a valve housing (11), can be displaced by a drive and placed with its front face against a valve seat (13), the valve housing (11) being completely filled with fluid. The actuating piston is formed by a hollow body (1), which is permeable to fluid at both ends in the direction of its axis and surrounds a cavity. The cavity is sealed off with respect to the valve housing (11) by a first sealing element (10) extending transversely to its axis and by a second sealing element (12) extending transversely to its axis with respect to a dividing wall (6) contained in the cavity and displaceable in the direction of the axis. On that side of the first (10) and the second (12) sealing element which faces away from the valve seat (13), the valve housing (11) is filled with a hydraulic, incompressible sealing liquid. ……
