Abstract

Pour empêcher, dans le cas d'une pompe à vide à palettes comportant un rotor 4 en métal fritté, que de l'huile soit projetée par le rotor 4 dans le canal d'aspiration 6, ce dernier débouche sur une face frontale du rotor 4. Application : notamment aux pompes à vide pour servo-freins de véhicules automobiles à moteur Diesel.
