Abstract

Rotor de ventilation. Il comporte un disque 18 calé portant des pales incurvées 24 dépassant au-dessous et au-dessus et équipées d'ailettes marginales inférieures 34, pales et ailettes étant de hauteur décroissante à partir du centre. Sur les bords supérieurs horizontaux des pales 24 est fixé un couvercle annulaire 40 formant entrée d'air. La fixation des pales peut être prévue réglable pour modifier le diamètre du rotor. Application à l'aération des liquides par rotation de leur surface libre.
