Abstract (en)

[origin: EP2354564A1] The pipe burst protection has a valve stem which is pre-stressed in a closing direction by a spring. A flat area is provided on the valve stem. A static pressure of the hydraulic fluid in a hydraulic line (5) exerts an opening force component on the valve stem. The opening force component acting on the valve spindle with an opening force component, opens a safety valve.
