    摘要: Disclosed is a valve comprising a valve member (72) that is guided so as to be movable in the direction of the longitudinal axis (73) thereof, extends into a valve pressure chamber (77), and is provided with a sealing surface (81) on a face which runs perpendicular to the longitudinal axis (73) thereof inside the valve pressure chamber (77). Said sealing surface (81) of the valve member (72) cooperates with a valve seat (79) that runs perpendicular to the longitudinal axis (73) thereof so as to at least largely close an opening (78) which is surrounded by the valve seat (79) relative to the valve pressure chamber (77). A connection (64) to a low-pressure area lies immediately next to said opening (78). The inventive valve member (72) is also provided with a peg (83) which extends into the connection (64) and by means of which liquid that flows out of the valve pressure chamber (77) when the sealing surface (81) of the valve member (72) is lifted from the valve seat (79) is directed in such a way that said liquid applies at least nearly no resulting force onto the valve member (72) in the direction of the longitudinal axis (73) thereof.

    摘要: The valve has a valve member (72) that is guided so that it is able to slide in the direction of its longitudinal axis (73), protrudes into a valve pressure chamber (77) and, in the valve pressure chamber (77), has a sealing surface (81) at an end extending transversely in relation to its longitudinal axis (73), with which sealing surface (81) the valve member (72) cooperates with a valve seat (79) extending transversely in relation to its longitudinal axis (73) in order, at least to a large extent, to close an opening (78) encompassed by the valve seat (79) in relation to the valve pressure chamber (77). The opening (78) is adjoined by a connection (64) leading to a low-pressure region. The valve member (72) has a pin (83) that protrudes into the connection (64) and, when the sealing surface (81) of the valve member (72) is lifted away from the valve seat (79), this pin (83) conveys fluid flowing out of the valve pressure chamber (77) in such a way that the outgoing fluid exerts at least approximately no resulting force on the valve member (72) in the direction of its longitudinal axis (73).
