Abstract
The valve (31) 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 and sliding 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). The plug (40) comprises an inner cavity (70), the bottom of which has a cross-section in the shape of an open 'V'. In this cavity (70) is a ball (72) which prevents the cylinder from being filled when the latter is inclined sufficiently for the ball not to be situated at the bottom of the cavity (70).
