Abstract

Compresseur rotatif comprenant un rotor à ailettes et un diffuseur à aubes fixes. Des fentes sont formées dans les faces latérales des aubes du diffuseur et débouchent dans des cavités à l'intérieur des aubes. Les cavités communiquent, par des orifices prévus dans la paroi du diffuseur, avec un collecteur fermé commun. L'interconnexion ainsi obtenue entre les différents canaux du diffuseur augmente la plage de fonctionnement du compresseur par l'équilibrage rapide des surpressions apparaissant dans un ou plusieurs canaux. L'invention s'applique particulièrement aux compresseurs d'air pour alimentation de moteurs d'avion à turbine à gaz.
