Abstract

Une buse (1) pour un tube de Venturi à haut entraînement par le vide, destiné à recueillir les poussières d'une ponceuse orbitale a une forme qui améliore le jet (10) au niveau de cette buse, favorise l'uniformité du profil des vitesses (7) sur le diamètre de la buse (1), et réduit l'épaisseur de la couche de cisaillement (6) grâce à une buse (1) à angle d'approche faible, un écoulement en régime intermédiaire sans turbulences dans l'étranglement (2) du tube et une zone de diffusion (3) à profil courbe.
