Abstract

Die Erfindung betrifft ein selbstgesteuertes Wechselventil (1) für Druckmedien, mit einem Ventilgehäuse (2) mit zwei Einlässen (4, 6) und einem Auslaß (8) sowie mit einem innerhalb des Ventilgehäuses (2) derart durch Druckunterschiede zwischen den Einlässen (4, 6) beweglich geführten Ventilelement (10), dass der Auslaß (8) selbsttätig mit dem jeweils einen höheren Druck (P1/P2) führenden Einlaß (4 oder 6) verbunden und der jeweils andere Einlaß (6 oder 4) abgesperrt wird. Das Ventilelement (10) ist kolbenartig mit zwei einander gegenüberliegenden, mit einlaßseitigen Ventilsitzflächen (18, 20) zusammenwirkenden Weichdichtungen (14, 16) ausgebildet. Bevorzugt ist auf dem Ventilelement (10) eine Dichtungsschutzhülse (26) derart verschiebbar geführt, dass in jeder der beiden Dichtstellungen des Ventilelementes (10) die dem jeweils abzusperrenden Einlaß (4 oder 6) zugekehrte Weichdichtung (14 oder 16) zur Anlage an der zugehörigen Ventilsitzfläche (18 oder 20) freigegeben und die andere, gegenüberliegende Weichdichtung (16 oder 14) von der Dichtungsschutzhülse (26) überdeckt wird.
