Abstract

L'invention entre dans le domaine des compresseurs centrifuges. Compresseur centrifuge à haut rapport de pression comportant un rouet muni d'aubes, caractérisé en ce que le rouet comporte une surface de révolution dont la méridienne est une courbe concave entraînant entre l'entrée et la sortie du rouet un changement de direction inférieur à 90 degrés , les aubes étant faiblement courbées et leur ligne de raccordement avec la surface de révolution du rouet faisant avec la bordure extérieure du rouet un angle beta aigu, en ce que la trace des aubes, sur un plan quelconque coupant la roue perpendiculaires à son axe, est rayonnante et en ce que l'extrémité de sortie des aubes fait un angle aigu gamma avec la surface du rouet à sa sortie qui est conique. Application : compression centrifuge à haut rapport de pression.
