Abstract

Pompe à engrenage. La pompe comporte un corps 35 dans lequel est formée une chambre de pompage dans laquelle s'engrènent deux éléments d'engrenage 32, 46 à denture extérieure, un élément d'engrenage 32 étant accouplé par des cannelures à un arbre d'entraînement 30 qui s'étend à l'extérieur du corps 35. Les faces axialement orientées de l'arbre 30 sont isolées de la pression régnant dans la chambre de pompage par un joint 36, ce qui supprime la nécessité d'avoir à utiliser un palier de butée pour l'arbre 30, même si la pression de la chambre de pompage devient élevée. Application aux pompes à carburant de moteurs.
