<p>The working piston (15) in the cylinder (1) is subjected to the force of the pressure medium only on one side, whereas the piston return travel results from reaction forces (R). The supply and discharge of the pressure medium are effected via separate conduits (9, 10), so that there is a continual replacement of the pressure medium within the cylinder (1). At the maximum of the pistons stroke, the pressure medium may be discharged out of the cylinder (1) independently of the control position of the control unit (2). In both end positions of the piston (15), the motion of the piston is braked by a mechanical dumping device (18).</p> |
