Abstract

La présente invention a pour objet un ventilateur axial comportant un rotor à pales réglables dont l'extrémité de base est montée sur le moyeu du rotor par l'intermédiaire d'un tourillon de fixation. Elle est caractérisée en ce que ce ventilateur axial comporte un dispositif de réglage commun à toutes les pales, mobile sur le rotor de façon à pouvoir se déplacer dans sa direction axiale pour changer l'angle de pales et pouvant également tourner coaxialement par rapport au rotor, et en ce qu'il est prévu des moyens de transmission de mouvement comprenant un bras accouplé rigidement à une extrémité au dispositif de réglage et articulé par son autre extrémité sur un bras de réglage fixe sur la pale correspondante afin de pouvoir exécuter à la fois un mouvement longitudinal et un mouvement universel. Elle se rapporte à des ventilateurs industriels.
