Abstract

L'invention concerne une pompe à engrenage (1), en particulier une pompe à huile à engrenage d'une boîte de vitesses automatique d'un véhicule automobile, comprenant un carter de pompe (2) et un couvercle de pompe (3) ou une bride de guidage d'huile, pour laquelle, dans le cas d'une pompe à engrenage, la roue dentée de pompe (6) motrice et, dans le cas d'une pompe à palettes, la roue à palettes, sont entraînées par un entraîneur de pompe (5) en liaison fonctionnelle avec l'arbre d'entraînement de pompe (4). Les surfaces de l'entraîneur de pompe présentent une inclinaison telle que la roue dentée de pompe (6) motrice est guidée axialement en direction du carter de pompe (2) et parvient en appui contre le carter de pompe (2).
