Abstract

Eine Vorrichtung (1) zum Erzeugen einer Arbeitskraft, insbesondere für Rammen, Pressen und dgl., besteht aus einem in einem Zylinderraum (3) verschiebbaren Arbeits kolben (4), einer vom Arbeitskolben (4) getrennten, über eine Koppeleinrichtung (6) mit demselben verbindbaren Kolben­ stange (5), einem die Arbeitskraft liefernden, dauernd unter dem Druck eines Energiespeichers stehenden Primärzylin­ derraum (3a) und einem von der Kolbenstange (5) durch­ drungenen, vor Arbeitsbeginn mit einem Druckmittel zum Kraftausgleich des Arbeitskolbens (4) befüllbaren Sekundär­ zylinderraum (3b), der einerseits mit dem Primärzylinder­ raum (3a) verbindbar und andererseits an eine Entspan­ nungseinheit angeschlossen ist.
Um die bei der Rückstellung von Arbeitskolben (4) und Kolbenstange (5) noch vorhandene Energie speichern und beim folgenden Arbeitshub ausnutzen zu können, ist im Primärzyiinderraum (3a) eine axial verschiebbare, mit dem Arbeitskolben (4) zusammenwirkende und mit einem umlau­ fenden Bund (10) an einem Anschlag (11) zum Anliegen bringbare Hülse (9) mit unterschiedlichen druckwirksamen Flächen angeordnet.
