Abstract
MACHINE CENTRIFUGE PERFECTIONNEE. DANS UN VENTILATEUR OU COMPRESSEUR, PAR EXEMPLE, L'ON INJECTE PAR DES TUYERES TANGENTIELLES INTERIEURES 11, 10 UNE COUCHE MINCE DE FLUIDE AUXILIAIRE CONTRE LA VOLUTE POUR EN ISOLER LE FLUIDE PRINCIPAL ET TENDRE A L'AMENER A TOURNER SUIVANT LE REGIME IRROTATIONNEL. L'UNE 11 DE CELLES-CI SE TROUVE ASSOCIEE AU BOSSAGE 16 DE REGULARISATION DU COURANT FLUIDE PASSANT DU MOUVEMENT TOURNANT AU MOUVEMENT RECTILIGNE. LE FLUIDE AUXILIAIRE PEUT ALIMENTER SOUS PRESSION LES JOINTS TELS QUE 22 ET REFROIDIR LES AUBES 7. SUPPRESSION DES MICRO-TOURBILLONS ET PROTECTION CONTRE LES FLUIDES AGRESSIFS.
