Abstract (en)
[origin: US6938413B2] There is disclosed a hydraulic control arrangement for damping driving vibrations of a mobile machine, comprising a lifting cylinder supporting a working tool whose cylinder chambers can be connected to a fluid source or a tank via a control valve arrangement. The hydraulic control arrangement has a damping valve arrangement including a control valve in which a check valve is integrated through which a bottom-side chamber of the lifting cylinder is connectable to a hydraulic accumulator. In the pressure control function the accumulator can be connected to a tank so that the accumulator pressure is restricted to a maximum value.
