Abstract

L'invention vise à permettre un fonctionnement sans aucune réduction de l'efficacité de l'hélice ni aucune réduction de la plage de fonctionnement, même lors du fonctionnement dans un environnement de fonctionnement qui comprend des liquides. A cet effet, l'invention porte sur un compresseur centrifuge, lequel compresseur comporte un arbre rotatif entraîné en rotation et une hélice ayant de multiples pales maintenues sur un moyeu fixé à l'arbre rotatif et disposées à des intervalles prédéterminés dans la direction périphérique de ce dernier, lequel comprime un fluide par la rotation de l'hélice, et lequel est caractérisé en ce que de multiples trous traversants pénétrant à partir du côté avant de l'hélice jusqu'au côté arrière de cette dernière sont réalisés sur le moyeu.
