Abstract

Roue de ventilateur comportant un moyeu, des pales moulées d'une seule pièce avec ce dernier, un chapeau de fermeture côté entrée et un déflecteur côté sortie. Le moyeu 1 de la roue de ventilateur, les pales 2 et 3 de cette roue et le chapeau de fermeture 4 représentent les parties d'un élément moule d'une seule pièce pouvant être fabriqué au moyen de poinçons de moulage que l'on peut retirer axialement, et le déflecteur 5 est fixé au moyeu 1, sous forme d'élément distinct, par un centrage 11. Ceci permet d'obtenir un balourd sensiblement réduit. L'invention s'applique en particulier aux ventilateurs à air de combustion à grande vitesse.
