Abstract

Die Erfindung betrifft eine Anordnung (10) zur Versorgung eines Hydrauliksystems mit Hydraulikflüssigkeit, mit einem Arbeitsreservoir (12) zur Aufnahme der zum Betrieb des Hydrauliksystems vorgesehenen Hydraulikflüssigkeit und mit einem mit dem Arbeitsreservoir (12) über eine Hydraulikleitung (14) in Verbindung stehenden Hilfsreservoir (16) zur Zwischenspeicherung von aus dem Arbeitsreservoir (12) entnommener Hydraulikflüssigkeit. Erfindungsgemäß ist eine Luftfördereinrichtung (28) vorhanden, die niederdruckseitig einerseits mit einer in einen flüssigkeitsfreien Bereich (30) des Hilfsreservoirs (16) mündenden Ansaugleitung (32) verbunden ist, sodass sich gegenüber dem atmosphärischen Umgebungsdruck ein Unterdruck in dem Hilfsreservoir (16) aufbauen lässt, und die andererseits mit einer Steuerleitung (34) verbunden ist, die eine Steueröffnung (36a, 36b) aufweist, die zumindest vor Inbetriebnahme der Luftfördereinrichtung (28) von der im Arbeitsreservoir (12) befindlichen Hydraulikflüssigkeit bedeckt ist.
