Abstract

L'invention concerne une cartouche (60) permettant de stocker du gaz liquéfié sous pression et comprenant un récipient (67) et une valve (30). La valve (30) comporte une gaine (31) montée sur le récipient (67), qui renferme un corps creux (34) avec une entrée (39) et une sortie. Le corps creux (34) comporte à l'intérieur un élément mobile (35) se déplaçant entre une position qui permet l'écoulement du gaz vers l'extérieur à partir de la cartouche (60) et une position qui ne le permet pas. Le corps creux (34) a une extrémité qui est à l'intérieur du récipient (67) et scellée avec un fond (38) qui ne permet pas l'écoulement du gaz depuis ladite extrémité vers l'intérieur du corps creux (34). Le fond (38) ne permet pas l'écoulement du gaz sous forme liquide ou gazeuse à l'intérieur du corps creux, et assure un écoulement impeccable du fluide sans provoquer l'obstruction de la valve.
