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. An die Öffnung (78) schließt sich eine Verbindung (64) zu einem Niederdruckbereich an. Das Ventilglied (72) weist einen in die Verbindung (64) ragenden Zapfen (83) auf, durch den bei mit seiner Dichtfläche (81) vom Ventilsitz (79) abgehobenen Ventilglied (72) aus dem Ventildruckraum (77) abströmende Flüssigkeit derart geleitet wird, dass durch diese zumindest annähernd keine resultierende Kraft auf das Ventilglied (72) in Richtung seiner Längsachse (73) ausgeübt wird.
