Said pressure chambers can beconnected to a pump or a tank by means of a control valve arrangement in order toactuate the differential cylinder. The pressure in a pressure chamber is defined by a pilot-operated pressure relief valve provided with a pressure switching stage, by which meansthe pressure regulated by the pressure relief valve can be lowered according to thepressure in the other pressure chamber.
