Abstract

Dispositif permettant de repousser vers les faibles débits, la limite de pompage des turbomachines à roues centrifuges. Il consiste à prévoir un opercule annulaire fixe, de préférence réglable, diminuant légerement le diamètre de l'ouïe fixe d'entrée du fluide dans la roue. Utilisé en particulier dans les compresseurs centrifuges fonctionnant sur un circuit dont l'ouverture est susceptible de diminuer fortement.
