Abstract

Bei einer Hydraulik-Ventileinrichtung mit einem einen Schiebekolben aufweisenden doppeltwirkenden Zylinder mit zwei Ein- oder Ausgängen für das der Steuerung des Schiebekolbens im Zylinder dienende Hydraulikmedium wie ein Hydrauliköl ist wenigstens einem Ein- oder Ausgang ein manuell, gesteuert oder automatisch einstellbares Sitzventil zugeordnet. Dadurch werden Nachteile auf Grund Leckage des Schubkolbens vermieden. Durch diese Maßnahme kann die Lebensdauer von Hydraulik-Ventil-Einrichtungen auch bei Alterung und Verschleiß verlängert werden.
