Hydraulic drive system has a cylinder bushing (40) connected to a dosing piston pump (3) directly on its housing. A hydraulic working piston (1) slides into the bushing forming a component body. Preferred Features: Oil pumped through the dosing piston pump is guided in a closed air-tight circulation. The circulation for the oil drives the working piston in a double-acting function. The movement of the working piston is controlled by the magnetic strength of a magnetic coil (7). Recoil of the working piston is regulated and/or blocked by controlling the oil volume stream using corresponding adjusting parts (11). |
