Abstract

Cette buse à allumage par étincelles comprend un tube intérieur (1) et un tube extérieur (2) entre lesquels est prévu un passage de mélange gazeux (22) s'étendant axialement. Un tube isolateur (5) est interposé entre les tubes intérieur et extérieur de façon à être exposé au mélange de gaz. Le tube isolateur a son extrémité avant qui affleure celle du tube intérieur (1), ou est en retrait par rapport à celle-ci. Un passage annulaire (11) est prévu de manière à communiquer avec les sorties des rainures (16) de passage du mélange gazeux. Ceci permet d'augmenter la durée de vie de l'isolateur (5) ainsi que la fiabilité de l'allumage.
Application aux chalumeaux d'oxycoupage.
