Abstract
Bei einem Hydraulikzylinder (1) mit einem Zylinderrohr (2), mit einem das Zylinderrohr (2) an seinem einen Ende (20) bis auf einen Ölanschluß (17) verschließenden Bodenstück (16), mit einem in dem Zylinderrohr (2) in Richtung einer Zylinderachse (4) geführten Kolben (3), mit einer an dem Kolben (3) befestigten und an dessen anderen Ende (5) aus dem Zylinderrohr (2) austretenden Kolbenstange (24) und mit einem auf das Zylinderrohr (2) aufgeschraubten, mindestens einen Schwenkzapfen (10) zur verschwenkbaren Lagerung des Hydraulikzylinders (1) ausbildenden Schwenkkopf (6) ist vor dem Schwenkkopf (6) ein Konterring (12) auf das Zylinderrohr (2) aufgeschraubt, so daß der Schwenkkopf (6) mit dem Konterring (12) relativ zu dem Bodenstück (16) und dessen Ölanschluß (17) in jeder gewünschten Drehstellung um die Zylinderachse (4) festlegbar ist. In the case of a hydraulic cylinder (1) with a cylinder tube (2), with a bottom piece (16) closing the cylinder tube (2) at one end (20) except for an oil connection (17), with one in the cylinder tube (2) in the direction a cylinder axis (4) guided piston (3), with a piston rod (24) attached to the piston (3) and at the other end (5) emerging from the cylinder tube (2) and with a piston rod screwed onto the cylinder tube (2), At least one pivot pin (10) for the pivotable mounting of the hydraulic cylinder (1) forming the pivot head (6) has a counter ring (12) screwed onto the cylinder tube (2) in front of the pivot head (6) so that the pivot head (6) with the counter ring ( 12) relative to the base piece (16) and its oil connection (17) can be fixed in any desired rotational position about the cylinder axis (4).
