Abstract

L'invention concerne une buse de traitement de surface destinée à projeter des particules solides entraînées dans un flux de gaz sous pression, ladite buse comportant un canal qui présente, dans le sens de l'écoulement des particules solides, d'abord un tronçon convergent (6) puis un tronçon divergent (7) qui débouche à l'extérieur de la buse par une fente de sortie (4) et qui présente une section de forme aplatie parallèlement à cette fente de sortie (4), au moins au voisinage de ladite fente de sortie (4). Le canal présente des variations de sections progressives sur toute sa longueur, le tronçon convergent (6) comporte une extrémité d'aval (5) aplatie parallèlement à la fente de sortie, et le tronçon divergent présente deux parties latérales de section élargie (4¿1?).
