Abstract

Die Erfindung betrifft Einrichtungen zur Erhöhung der Arbeitsleistung hydraulisch betriebener Werkzeuge mit einer wenigstens eine Pumpe aufweisenden Hydraulikvorrichtung. Diese zeichnen sich insbesondere durch eine einfache Realisierung aus. Dazu ist nach der Pumpe in Richtung Werkzeug ein Drosselrückschlagventil angeordnet, wobei das Drosselrückschlagventil das Medium ungedrosselt in Richtung des Werkzeugs und gedrosselt in Richtung der Pumpe durchfließen lässt. Die wenigstens eine Pumpe der Hydraulikvorrichtung fordert das Medium insbesondere in Form eines Öls in Richtung Drosselrückschlagventil und Werkzeug. Das Drosselrückschlagventil ist in der Pumprichtung auf Durchfluss und in der Rückflussrichtung als Drossel eingebaut. Die Leitung in Form eines Schlauchs ist dabei ein Druckspeicher.
