RIDUTTORE DI PRESSIONE DI BOMBOLA DI GAS

摘要

The relief valve is designed so as to make it possible for a cylinder to be filled with a gas and to enable this gas to be drawn off at a relatively low and stabilized pressure. In order to make the filling possible through the pressure-relief device, the relieving piston (34) has a bypass pipe (52) passing through it and is linked on the upstream side and on the downstream side with two valves (18) and (28) which enable the cylinder to be filled.
