Hydraulic oil is transported between the piston side (10) of the piston-cylinder unit and the piston connecting rod side (11) through a telescopic tube (21). Both the pressure lubrication system (24-30) for lubricating the bearing between the piston-cylinder unit (1, 2) and the stationary bearing support (7) and devices (12-18) for feed of hydraulic medium under pressure to both sides (10, 11) of the piston-cylinder unit are arranged in a bearing pin (6) around which the piston-cylinder unit can pivot. |
