ABSTRACT:
The tap comprises inside the cylinder, a two-way valve (30) permitting both filling and draining of the gas cylinder.
The valve (30) comprises at least two lateral openings (34, 36) which can be sealed off by a sealing device (40) provided with an axial orifice (48) for the passage of gas and which slides axially in the shell (32) between a position of obstruction of the openings (34, 36), through the effect of a spring (44), and a position of opening against the action of the spring (44), through the effect of the pressure of the filling gas and a level-controlling valve (52) actuated by a float (62) at the bottom of the shell (32).
