Abstract
Das Ventil weist ein Ventilglied (72) auf, das in Richtung seiner Längsachse (73) verschiebbar geführt ist, das in einen Ventildruckraum (77) ragt und im Ventildruckraum (77) an einer quer zu seiner Längsachse (73) verlaufenden Stirnseite eine Dichtfläche (81) aufweist, mit der es mit einem quer zu seiner Längsachse (73) verlaufenden Ventilsitz (79) zum zumindest weitgehenden Verschließen einer vom Ventilsitz (79) umgebenen Öffnung (78) gegenüber dem Ventildruckraum (77) zusammenwirkt Die Dichtfläche (81) an der Stirnseite des Ventilglieds (72) ist von einer Ringfläche (84) umgeben, die bei mit seiner Dichtfläche (81) am Ventilsitz (79) anliegendem Ventilglied (72) in Richtung von dessen Längsachse (73) mit geringem Abstand (A) vom Ventilsitz (79) angeordnet ist. Das Ventilglied (72) weist mehrere über dessen Umfang verteilte Durchlässe (86) auf, durch die die Öffnung (78) bei mit seiner Dichtfläche (81) am Ventilsitz (79) anliegendem Ventilglied (72) mit dem Ventildruckraum (77) verbunden ist. The valve has a valve member (72) which is displaceable in the direction of its longitudinal axis (73), which projects into a valve pressure chamber (77) and a sealing surface in the valve pressure chamber (77) on an end face running transversely to its longitudinal axis (73) ( 81), with which it interacts with a valve seat (79) extending transversely to its longitudinal axis (73) for at least largely closing an opening (78) surrounded by the valve seat (79) with respect to the valve pressure chamber (77) The end face of the valve member (72) is surrounded by an annular surface (84) which, when the valve member (72) bears on the valve seat (79) with its sealing surface (81) in the direction of its longitudinal axis (73) with a small distance (A) from the valve seat ( 79) is arranged. The valve member (72) has a plurality of passages (86) distributed over its circumference, through which the opening (78) is connected to the valve pressure chamber (77) when the valve member (72) lies against the valve seat (79) with its sealing surface (81).
