When the grain is executed , it is designed in such a way that it is effective as a result of the leodroaseit, both when the load is applied and when the load is removed, and that it becomes effective depending on the need without a specific adjustable Wundestireg® control valve.

To explain the invention, it should be added. on the publication (St © in) in the Schweizerische Bauseitung (65® year 1fr · 39 * page 531 ff · ₉ especially picture 3) Terf # iesea _? where the connection between the opening of the control valves and the adjustment speed of the servomotor in today's loodroa controller (cataract glider) is explained in particular the limit of the slick pressure on the pressure to it through a throttle "b« limit @ a adjustment speed of the S ^ rTOBotorö ^ d »h · above all the« lower limit of the throttled »st @ tter ¥ © rgaag is reduced. This implies that the size of the effective opening of the star valve over a certain value as the adjustment speed of the servo motor does not influence much _f whereas, for example, the oil brake of the Isodr © s © iariclituiig occurring Kuifenrückdräusiig even with a stroke of the control valve piston over the range, because with its adjustment a leader tang of the displacement speed is still effective It can therefore Deactivating the process to slow down into the new steady state.
