Abstract
Pompe centrifuge comprenant une roue à ailettes et un diffuseur. Les ailettes 4 comportent à l'extrémité 5 du côté de la sortie du fluide de travail au moins un passage de circulation 6, 7, destiné à ce dernier. Application aux compresseurs centrifuges afin d'abaisser le niveau de pression sonore du sifflement émis en général à certaines vitesses par la roue.
