Abstract

L'invention concerne un procédé permettant la fabrication en grandes séries de buses à fermeture automatique pour briquets à gaz. La buse à fermeture automatique est conçue de telle façon que lorsque le briquet est allumé pour être utilisé et qu'il reste exceptionnellement continuellement allumé, un enroulement en alliage à mémoire de forme et une soupape (seconde soupape), montés dans le tube de la buse servant de passage au flux de gaz, bloquent le flux de gaz, éteignant ainsi le briquet. Pour le montage d'un tel briquet, il est nécessaire de réduire le nombre de pièces, de faciliter le travail de montage et de garantir le fonctionnement positif (fermeture) ainsi que le retour en position initiale (position à partir de laquelle on peut réallumer le briquet). A cet effet, une extrémité de l'enroulement en alliage à mémoire de forme est ancré au moyen de l'extrémité d'une soupape (première soupape) montée dans le briquet. Cette conception permet la production en grandes séries de buses à fermeture automatique dont le fonctionnement et le retour en position initiale sont fiables, et qui sont économiques.
