Abstract
The invention concerns a hydraulic line coupling arrangement of a consumer, with a pump line, a tank line and a safety valve in the pump line, the valve element of the safety valve being acted upon in the opening direction by an opening pressure from the pump line and in the closing direction by a closing pressure of a closing pressure connection. In such an arrangement it is desired to prevent overloading of the consumer. For this purpose, a pilot valve is provided for controlling the closing pressure, the position of the pilot valve being controlled by the pressure in the tank line.
