<p>The invention relates to a hydraulic line coupling arrangement for a load (1), with a pump line (9), a tank line (10) and a safety valve (11) in the pump line (9), the valve element of the safety valve being acted upon in the opening direction by an opening pressure from the pump line (9) and in the closing direction by a closing pressure at a closing pressure connection. The problem is to prevent overloading of the load (1). To solve the problem, a pilot valve (20) is provided for controlling the closing pressure, the position of the pilot valve being controlled by the pressure in the tank line (10).</p> |
