ABSTRACT:
The valve (30) comprises at least two lateral openings (34, 36) which can be shut off by a plug (40) provided with an axial orifice (48) for the passage of gas, which plug slides axially in the casing (32) between a position in which the openings (34, 36) are shut off under the influence of a spring (44) and an open position counter to the action of the spring (44) under the influence of the pressure of the filling gas, and a level valve (52) activated by a float (62) at the bottom of the casing (32).
In order to prevent pressure from building up inside the casing (32) after closure, the latter is provided with escape orifices (50) which are associated with resilient opening means (64).
