Abstract

Die vorliegende Erfindung betrifft einen mehrstufigen, doppelt wirkenden Hydraulikzylinder mit Hydraulikanordnung, und mit einer Schaltanordnung, durch die wahlweise wenigstens einem Ringraum oder wenigstens einem der zwischen den Kolben der Kolbenstangen bzw. zwischen dem Kolben der ersten Kolbenstange und dem Gehäuseboden ausgebildeten Kammern Hydraulikfluid zuführbar ist, wobei die entsprechende andere Seite des Kolbens mit einem Vorratstank verbunden ist, wobei die Ringräume (18) untereinander durch Schaltbohrungen (24) in der Kolbenstange (16) fluidisch miteinander verbunden sind, wobei die Schaltbohrungen (24) durch den Kolben der nächstinneren Kolbenstange überfahrbar sind und dann eine fluidische Verbindung zwischen der Kammer (32) der äußeren Kolbenstange und dem Ringraum (18) der nächstinneren Kolbenstange hergestellt ist, und wobei in der Verbindung mit dem Vorratstank (68) ein Sperrventil (66) angeordnet ist, mittels dessen der Rückfluß von Hydraulikfluid vom Hydraulikzylinder (10) zum Vorratstank (66) absperrbar ist.
