Abstract

Pompe volumétrique en volute. Elle comporte deux éléments correspondants en volute, à savoir un élément fixe et un élément mobile qui exécute un mouvement orbital par rapport à l'élément fixe. Chacun de ces éléments comporte une plaque extrême et une spire solidaire de cette plaque et formant un tour et demi de développante. Le mouvement orbital de l'élément mobile par rapport à l'élément fixe provoque la formation de poches entre les spires, ces poches ayant des volumes qui varient de manière à faire circuler un liquide dans lequel la pompe peut être immergée. Domaine d'application : pompes à carburant pour véhicules.
