Abstract

Hydraulikzylinder, umfassend einen hohlzylinderförmigen Mantel (1), der stirnseitig beiderseits durch jeweils einen Deckel (2, 3) druckdicht verschlossen ist, wobei im Mantel (1) ein axial zwischen den Deckeln (2, 3) hin und her beweglicher Kolben (4) angeordnet ist, der zwei Druckräume (5, 6) voneinander trennt und umfassend zumindest einen Druckkompensator (7.1, 7.2, 7.3, 7.4), der in zumindest einem der Druckräume (5, 6) angeordnet ist.

Figure imgaf001
Hydraulic cylinder, comprising a hollow cylindrical shell (1), the front side on both sides by a respective cover (2, 3) is pressure-tight, wherein in the shell (1) axially between the covers (2, 3) reciprocating piston (4) is arranged, the two pressure chambers (5, 6) separated from each other and comprising at least one pressure compensator (7.1, 7.2, 7.3, 7.4), which is arranged in at least one of the pressure chambers (5, 6).
