Abstract

Eine hydraulische Druckversorgungseinheit weist zwei abwechselnd druckbeaufschlagte Ausgänge (6, 7), eine reversierbare Pumpeneinheit mit zumindest zwei Pumpen (9 10) und einen alle Pumpen gemeinsam antreibenden reversierbaren Elektromotor (11) auf, allenfalls mit gegenseitig entsperrenden Rückschlagventilen (8) vor den Ausgängen. Weiters ist eine Versorgung für Hydraulikmedium vorgesehen. Eine Pumpe ist als Niederdruckpumpe (10) und eine Pumpe als Hochdruckpumpe (9) ausgelegt, wobei die druckbeaufschlagten Ausgänge beider Pumpen an den gleichen Ausgang (6, 7) der Druckversorgungseinheit gelegt sind.
Um für beide Arbeitsrichtungen bei einfachem Aufbau und höchstmöglicher Flexibilität in der Auslegung des Systems bis zum Erreichen eines vorgebbaren Druckniveaus eine große Menge an Hydraulikmedium und nach Erreichen dieses Druckniveaus Hydraulikmedium mit großem Druck zur Verfügung zu stellen, ist vorgesehen, daß beide Ausgänge der Hochdruckpumpe (9) von der Niederdruckpumpe (10) durch Rückschlagventile (10, 13) getrennt sind und jede Pumpe (9, 10) über ein eigenes Wechselventil (14, 15) mit der Versorgung für Hydraulikmedium verbunden ist, und daß beide Ausgänge der Niederdruckpumpe (10) über Druckschaltventile (16, 17) mit dem Tank (12) verbindbar sind, wobei die Steueranschlüsse der Druckschaltventile (16, 17) mit den Ausgängen der Hochdruckpumpe (9) derart verbunden sind, daß der Steueranschluß desjenigen Druckschaltventils (16, 17) auf der aktuell druckbeaufschlagten Seite vom aktuell druckbeaufschlagten Ausgang der Hochdruckpumpe (9) beaufschlagt wird.
