Abstract
A two-way valve is disclosed comprising at least two lateral openings which can be shut off by a piston provided with an axial orifice for the passage of gas, which piston slides axially in the casing between a position in which the openings are shut off under the influence of a spring and an open position counter to the action of the spring under the influence of the pressure of the filling gas, and a level valve activated by a float at the bottom of the casing. In order to prevent pressure from building up inside the casing after closure, the latter is provided with vent orifices. A seal member is arranged on the piston to cover or uncover the vent orifices.
