Abstract

L'invention se rapporte à un atomiseur utilisé lors de l'oxycoupage et du soudage au gaz et au combustible se composant d'un corps principal, d'un diffuseur, d'un tube étroit pour oxygène préchauffé, d'un tube fin pour combustible, d'un tube expansé et d'un tube fin pour oxygène préchauffé qui sont tous disposés de manière coaxiale au centre du corps, le tube expansé étant en communication avec le tube fin pour oxygène préchauffé et le tube fin pour combustible. Ledit tube expansé a une configuration conique dont l'extrémité élargie s'aligne avec une surface d'extrémité du corps et dont l'extrémité plus petite est reliée au tube fin pour oxygène préchauffé. Les avantages que présente cet atomiseur sont les suivants: il n'est plus nécessaire d'utiliser de pompe dans le réservoir à essence ce qui facilite les opérations; les éclaboussures et les fuites d'essence sont limitées; et une fois que l'on a ouvert la soupape à oxygène, le mélange de combustible et d'oxygène atomisés est versé hors de la buse. Lorsque la soupape à oxygène est refermée, l'alimentation en combustible est détenue de manière à améliorer la sécurité et à réduire le coût.
