ABSTRACT:
A circuit for limiting a static and/or dynamic pressure load in a hydraulically actuated use device which is controlled in a closed control circuit by means of a directional control valve and a mechanically or hydraulically releasable blocking device. Aa pressure control valve is arranged between the use device and the pressure relief valve and being adapted to discharge a hydraulic fluid from the use device to a tank when a predetermined hydraulic pressure in the use device is exceeded. The output port of the pressure relief valve is connected to a hydraulic control line is adapted to hydraulically connect the pressure relief valve to a control side of the control valve. Thus, the control valve is turnable by the discharging pressure of the pressure relief valve in a switching position in which a feed line leading to the use device is connected with the tank, and said blocking device is turned in a released state so that the hydraulic fluid in the use device is dischargeable to the tank via the blocking device and the control valve.
