Abstract

MACHINE DONT LES ORIFICES DE PASSAGE DU FLUIDE ONT UNE CONFIGURATION PERMETTANT D'AMELIORER L'ECOULEMENT DE CE FLUIDE. L'AXE DE DISTRIBUTION 60 CONTIENT DES PASSAGES 64 ET 66 D'ALIMENTATION ET DE RETOUR DE FLUIDE, DE SECTION SEMI-CIRCULAIRE, SEPARES PAR UN PONT 62. LES PASSAGES 64 ET 66 S'OUVRENT SUR DES ZONES D'ALIMENTATION ET DE DECHARGE 70 ET 72 DONT LES SURFACES TERMINALES 74, 76 SE RACCORDENT AU PONT 62. LES ARRETES 78 ET 80 DES ORIFICES DE CHARGE ET DE DECHARGES 82 ET 84 SONT INCLINEES VERS L'INTERIEUR ET VERS LES PASSAGES 64 ET 66 POUR AMELIORER L'ECOULEMENT.
