Abstract

Buse de pulvérisation à jet plat et faible dérive. La buse de pulvérisation est du type comprenant un corps(1), qui possède une zone d'entrée de fluide et un orifice de sortie de fluide, et qui loge : - un noyau (2), définissant intérieurement un passage, de section transversale croissante, en communication avec l’extérieur sensiblement au niveau de sa section transversale la plus faible, d’où un effet Venturi, - un insert (3), muni d’une fente de sortie définissant l’angle d’ouverture de la buse, le noyau (2) et l’insert (3) étant distants l’un de l’autre et formant entre eux une chambre de travail dans le corps (1). La buse comporte en outre une pièce additionnelle (7) dite éclateur, logée dans la chambre de travail, aménagée pour former un obstacle à l’écoulement du fluide, cet éclateur comprenant deux orifices axiaux traversants, formant chacun un passage fluidique, de part et d’autre d’un plan radial, de sorte que les deux flux passés par les orifices de l’éclateur se regroupent et viennent ensuite impacter la surface de la fente de sortie de l’insert, engendrant finalement un jet plat.
