Abstract

Roue de ventilateur axial (1) qui comporte un corps (2) constitué d'un moyeu cylindrique creux (4) et de plusieurs aubes (6) reliées au moyeu (4) et réparties sur la périphérie dudit moyeu. Chaque aube (6) du ventilateur s'étend axialement dans la zone d'un pied d'aube (8) relié au moyeu (4), puis de manière inclinée dans la direction périphérique entre un côté d'admission (10) et un côté d'évacuation (12) du moyeu (4). Sur son côté d'admission (10), le moyeu (4) présente un raccourcissement de sa longueur axiale dans la direction périphérique entre les pieds (8) des aubes (6) voisines, obtenu par la présence d'évidements (16) ménagés dans son bord.
