Abstract (en)

[origin: EP1743979A1] The arrangement has a hydraulic cylinder (12) with two chambers (24, 26), and a control valve (18) that is hydraulically connected with the chamber (24) and has two control positions (32, 34). The control valve in the position (32) allows a hydraulic flow only in the direction of the chamber (24). The control valve in the position (34) allows the hydraulic flow in and out of the chamber (24).The control valve is controllable such that it takes up the position (32) when the hydraulic cylinder takes up its position.
