<p>The tap (valve) includes, inside the bottle (cylinder), a two-way valve (30) allowing both the filling and emptying of the gas bottle. The valve (30) includes at least two lateral openings (34, 36) which can be sealed off by a stopper (40) provided with an axial orifice (48) for the passage of gas sliding axially in the housing (32) between a position in which the openings (34, 36) are obstructed, under the effect of a spring (44), and an open position against the action of the spring (44) under the effect of the pressure of the filling gas, and a level valve (52) actuated by a float (62) at the bottom of the housing (32). <IMAGE></p> |
