CLOSURE DEVICE FOR A PRESSURIZED-GAS INFLATABLE PRESSURE CONTAINER OF A COLD GAS GENERATOR

摘要

The invention relates to a closure device for a pressure reservoir (14) o f a gas-refrigeration generator (11), which pressure reservoir can be filled with a compressed gas. The valve body (21) is arranged so as to be displace able inside a valve box (18). The valve body (21) has an effective compressi ve surface facing the main chamber (15) and an effective compressive surface facing the prechamber (52), both surfaces having identical size and being i mpingeable with the filling pressure of the main chamber (15). The valve bod y (21) is retained in a closed position by an outer effective compressive su rface (64) which is subject to an atmospheric pressure in the direction of c losure and by an energy storing element (47).
