Abstract

L'invention concerne une motopompe et son procédé d'assemblage La motopompe comporte une pompe à fluide et un moteur électrique positionné précisément par plusieurs goujons qui sont en contact avec une surface interne d'un carter commun. L'utilisation d'une seule surface de référence permet d'éviter l'accumulation des tolérances et des imprécisions de positionnement de la pompe et du moteur. Une contre-plaque de la pompe présente une surface de portée soutenant une extrémité de l'arbre de l'induit du moteur. Une came annulaire de la pompe est également montée sur les goujons pour la positionner précisément par rapport au rotor et à l'induit. - Application aux motopompes, notamment pour le système de carburation des moteurs à combustion interne.
