Abstract

Abstract Translated from French 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. Air jet atomization spray nozzle. An air blast cap 50 includes a central bore 52 which surrounds the actual nozzle 38 with a fluid blast tip 26. Several holes 62 parallel to the axis are distributed regularly around the circumference of the central bore and intersect the edge thereof so as to form multiple gas flow passages regularly dimensioned and separated by radial ribs. These ribs are applied against the outer surface of the nozzle 38 so as to align the axis of symmetry with that of the central bore 52 of the air projection cap. General application to all electrostatic spray atomization devices by air jets.
