Abstract

Buse de pulvérisation par atomisation par jets d'air. Un chapeau de projection d'air 50 comprend un alésage central 52 qui entoure la buse proprement dite 38 d'un embout 26 de projection de fluide. Plusieurs trous 62 parallèles à l'axe sont répartis régulièrement à la circonférence de l'alésage central et en intersectent le bord de manière à former de multiples passages d'écoulement de gaz régulièrement dimensionnés et séparés par des nervures radiales. Ces nervures s'appliquent contre la surface extérieure de la buse 38 de manière à en aligner l'axe de symétrie sur celui de l'alésage central 52 du chapeau de projection d'air. Application générale à tous les dispositifs électrostatiques de pulvérisation à atomisation par jets d'air.
