Abstract

Dispositif de soupape (2) configuré pour retenir et sélectivement libérer un mélange gazeux contenu dans un volume intérieur d'une enceinte, le dispositif de soupape comprenant une embase (3) et un piston (4) monté mobile par rapport à l'embase entre une position de repos fermée et une position ouverte, l’embase comprenant une douille (31) et un rebord annulaire (32), dans lequel le piston, en position de repos fermée, est poussé contre un siège de soupape (8) par un ressort, le piston comprenant une membrane sécable (6) fermant en temps normal un passage central du piston délimité radialement par le piston, l'embase comprenant un épaulement par rapport auquel peut s'appuyer un outil de purge (9) configuré pour repousser le piston vers la position ouverte, le dispositif de soupape comprenant des passages (11,12), faisant communiquer, dans la position ouverte du piston, le volume intérieur avec un espace extérieur. Figure de l’abrégé : Fig. 2Valve device (2) configured to retain and selectively release a gas mixture contained in an interior volume of an enclosure, the valve device comprising a base (3) and a piston (4) mounted to move relative to the base between a closed rest position and an open position, the base comprising a sleeve (31) and an annular rim (32), in which the piston, in the closed rest position, is pushed against a valve seat (8) by a spring, the piston comprising a breakable membrane (6) normally closing a central passage of the piston delimited radially by the piston, the base comprising a shoulder against which a purge tool (9) configured to push the piston towards the open position can bear, the valve device comprising passages (11, 12), communicating, in the open position of the piston, the interior volume with an exterior space.
