ABSTRACT:
The tap comprises an external operating element and a connecting stem for transmitting the movement of the operating element to the opening and closure member which is arranged in such a way as to be pressed against the sealing seat under the effect of the pressure of the gas. To make opening against the pressure of the gas easier, the connecting stem and/or the opening and closure member are designed in such a way that the opening of the tap comprises a first phase in which the opening and closure member pivots, followed by a movement of the axial translation.
