Abstract

L'INVENTION A POUR OBJET UNE POMPE HYDRAULIQUE COMPORTANT UN ETAGE DE SURALIMENTATION. CET ETAGE DE SURALIMENTATION 2 CONSISTE EN UNE POMPE A PALETTES ASSOCIEE A UNE POMPE PRINCIPALE 1, DU TYPE AUTOREGULATRICE A PISTONS AXIAUX. LE ROTOR 24 DE LA POMPE A PALETTE EST ENTRAINE DIRECTEMENT PAR L'ARBRE D'ENTRAINEMENT 6 DE LA POMPE PRINCIPALE, DU COTE OPPOSE A CELUI OU SE TROUVE LA GLACE DE DISTRIBUTION 7 DE LA POMPE AUTOREGULATRICE 1 DONT LA LUMIERE D'ASPIRATION 13 SE TROUVE RELIEE A L'ORIFICE DE REFOULEMENT 36 DE LA POMPE A PALETTES PAR UNE CONDUITE INTEGREE DANS LE CORPS DE POMPE 10. APPLICATION AUX CIRCUITS HYDRAULIQUES A HAUTE PRESSION, NOTAMMENT POUR L'AERONAUTIQUE.
