Abstract

Offenbart ist eine Ventilanordnung (1,2) für eine mobile Arbeitsmaschine mit einem Zumess- bzw. Steuerventil (1), über das ein regenerierbarer Anschluss (C2) und ein weiterer Anschluss (C1) eines Verbrauchers - z.B. Arbeitszylinder oder Motor - der mobilen Arbeitsmaschine versorgbar sind. Es ist ein - vorzugsweise gesondertes - Regenerationsventil (2) mit nur zwei Schaltstellungen (ganz offen; ganz geschlossen) vorgesehen, über das Druckmittel vom regenerierbaren Anschluss in einen Tank (6) ableitbar ist. Oberhalb einer vorgegebenen Druckdifferenz zwischen den Anschlüssen ist das Regenerationsventil offen und im Übrigen geschlossen. Ein Haupt- bzw. Steuerschieber (14) des Steuerventils weist eine gemeinsame Regenerations- und Arbeitsstellung auf. Der Steuerschieber hat also keine entlang eines Verschiebeweges des Steuerschiebers von der Regenerationsstellung beabstandete Arbeitsstellung, so dass kein aktives Umschalten zwischen Arbeitsbetrieb und Regernationsbetrieb nötig ist.
