Abstract (en)
[origin: WO9939127A1] A closed, hoseless, pressurized lubrication and hydraulic oil system for a hydraulic piston-cylinder apparatus (1, 2), in which the cylinder part (1), with one end thereof (3, 5) is rotatably mounted in a stationary bearing block (7), and in which hydraulic oil is transported between the piston side (10) of the piston-cylinder apparatus and the piston rod side (11) thereof through telescopic tubes (21), and in which both the pressure lubrication system (24-30) for lubrication of bearings between the piston-cylinder apparatus (1, 2) and the stationary bearing block (7), and means (12-18) for supply of hydraulic fluid under pressure to the two sides of the piston-cylinder apparatus are provided in a bearing pin (6) about which the piston-cylinder apparatus is adapted to rotate.
