The invention relates to a gas regulating and/or controlling device comprising: a body (1) with a gas passageway, inlet (2) and outlet (3), the inlet and outlet being connected to the passageway; passageway closure means (5, 6, 7, 8); and movable means (9) defining with the body (1) of the device a low-pressure chamber (11) downstream of the closure means (5, 6, 7, 8), the movable means (9) operating the closure means (5, 6, 7, 8) as a function of the pressure in the low-pressure chamber (11). The closure means (5, 6, 7, 8) comprise a first closure member (5, 6) and a second closure member (7, 8), the latter downstream of the former inside the passageway, and the first and second closure members (5, 6, 7, 8) are mechanically connected so that the first closure member (5, 6) closes before the second (7, 8).
L'invention a trait à un dispositif de détente et/ou de régulation de gaz comportant: un corps (1) avec un passage, une entrée (2) et une sortie (3) de gaz, l'entrée et la sortie étant en liaison avec le passage; des moyens d'obturation (5, 6, 7, 8) du passage; des moyens mobiles (9) définissant avec le corps (1) du dispositif une chambre basse pression (11) en aval des moyens d'obturation (5, 6, 7, 8), les moyens mobiles (9) actionnant les moyens d'obturation (5, 6, 7, 8) en fonction de la pression régnant dans la chambre basse pression (11). Les moyens d'obturation (5, 6, 7, 8) comportent un premier obturateur (5, 6) et un second obturateur (7, 8) monté en aval du premier dans le passage, et le premier et le second obturateur (5, 6, 7, 8) sont liés mécaniquement de sorte que le premier obturateur (5, 6) ferme avant le second (7, 8).
