Abstract

Pompe centrifuge à double volute à section croissante non-linéaire Pompe (1) à carburant à double volute comprenant deux volutes (4, 5) s’étendant entre une admission (2) interne de fluide et un refoulement (3) externe de fluide, lesdites volutes (4, 5) définissant un flux centrifuge depuis l’admission (2) de fluide vers le refoulement (3) de fluide, chaque volute (4, 5) présentant une section croissante depuis une extrémité interne vers une extrémité externe, caractérisée en ce que pour chaque volute (4, 5), la section augmente de manière non linéaire depuis une extrémité interne vers une extrémité externe. Figure pour l’abrégé : Fig. 1.Double volute centrifugal pump with non-linear increasing section Double volute fuel pump (1) comprising two volutes (4, 5) extending between an internal fluid inlet (2) and an external fluid discharge (3), said scrolls (4, 5) defining a centrifugal flow from the fluid inlet (2) to the fluid discharge (3), each scroll (4, 5) having an increasing section from an inner end to an outer end, characterized in that for each volute (4, 5), the section increases non-linearly from an internal end towards an external end. Figure for abstract: Fig. 1.
