Abstract
Pompe à engrenage dans laquelle une roue dentée est montée sur un arbre de commande. L'extrémité de l'arbre de commande pénétrant dans la roue dentée présente une fente axiale dont un tronçon extrême élargi loge un axe transversal. Les extrémités de cet axe dépassant diamétralement de l'arbre sont destinées à se loger dans des rainures réalisées à l'intérieur de la roue dentée montée sur l'arbre. Domaine d'application pompes à engrenage d'alimentation en combustible.
