摘要

The rod has hydraulic cylinders (34, 36) including hydraulic chambers (44-50). Hydraulic lines (52, 54) are lead into the respective hydraulic chambers of the hydraulic cylinders. Opened throttle check valves (58-64) are provided through which a hydraulic flow is restricted into or unrestricted out of the hydraulic chambers. The hydraulic lines are arranged such that the hydraulic flow into the hydraulic chambers is connected with the hydraulic flow out of the hydraulic chambers. The hydraulic lines are connected with a hydraulic reservoir (56).
