Abstract

L'invention concerne un chalumeau comprenant un dispositif d'arrêt de retour de flamme et un dispositif d'arrêt thermique intégrés. Selon une approche, un corps de chalumeau comprend un passage de corps de chalumeau, et un ensemble cartouche disposé à l'intérieur du passage. L'ensemble cartouche peut comprendre : un dispositif sensible à la pression pouvant être réinitialisé et/ou un dispositif d'arrêt thermique, le dispositif sensible à la pression et le dispositif d'arrêt thermique pouvant être modifiés d'une première configuration à une seconde configuration en réponse à un gradient de pression ou de température dans le corps de chalumeau, la seconde configuration limitant l'écoulement à travers le passage. La cartouche peut comprendre en outre un clapet de non-retour disposé le long du passage, par exemple à l'intérieur d'un trou d'une douille, ou à l'intérieur d'un élément de retenue accouplé au corps de chalumeau au niveau d'une entrée du passage.
