Abstract

Druckabschneidungsventil (1) mit einem Wechselventilkolben (2b), der in einer Bohrung (3) des Druckabschneidungsventiles (1) gleitend angeordnet und durch Beaufschlagung mit dem jeweils höheren Druck eines Arbeitsmediums in einer von zwei Leitungen (A, B) zwischen zwei Endpositionen verschiebbar ist, wobei der Wechselventilkolben (2b) gegebenenfalls eine sich über seine gesamte Länge erstreckende Innenbohrung (4) aufweist, durch die ein Meßkolben (5) zur Druckabschneidung zumindest in einer der zwei Endpositionen des Wechselventilkolbens (2b) durch den höheren Druck beaufschlagt ist, wobei der Wechselventilkolben (2b) so ausgebildet ist, daß in beiden Endpositionen eine Verbindung (6) zwischen nur der Leitung (A bzw. B) mit dem jeweils niedrigeren Druck und zumindest einer Spülöffnung (7) zum Ausspülen des Arbeitsmediums freigegeben ist.
