Abstract

2. Die Erfindung betrifft eine Schaltvorrichtung zum Ansteuern mindestens einer hydraulischen Betätigungseinrichtung mit zwei gegenläufig wirkenden Rückschlagventilen 20, 22 in einer Zu- 24 und Ablaufleitung 26, die an die jeweilige Betätigungseinrichtung sowie an ein Schaltventil 28 angeschlossen sind. Dadurch, daß erfindungsgemäß parallel zu den beiden Rückschlagventilen 20, 22 geschaltet zwei entsperrbare Rückschlagventile 30, 32 vorhanden sind und daß die Steuerleitung 34 des ersten entsperrbaren Rückschlagventiles 30 an den Sperranschluß 36 des anderen entsperrbaren Rückschlagventiles 32 angeschlossen ist, ist eine Schaltvorrichtung zum Ansteuern mindestens einer hydraulischen Betätitigungseinrichtung, insbesondere in Form eines Hydrozylinders 10 geschaffen, mit der es möglich ist, für dahingehende Einrichtungen eine Schwimmstellung kostengünstig und funktionssicher mit wenig Komponenten zu erreichen.
