Abstract

The device cuts the gas flow off completely in the event of a leak in the main supply pipe to the consuming unit, and comprises a reservoir containing two different pressures. In the event of a leak, the pressure loss causes a gas supply shut-off valve to close. The lower part of the reservoir closed by a diaphragm can be filled with nitrogen gas to a weight of 1.70. Kg., a leak in the supply of propane gas to the chamber above the diaphragm causing the diaphragm to move a spring loaded valve plunger to its closed position.
