Abstract

L'invention concerne une pompe à palettes 1 destinée à un véhicule automobile, comportant une bride 15 et un carter de pompe 7, 13. Le carter de pompe 7, 13 est fixé à la bride 15 et la bride 15 fournit un canal de liaison 18 entre un espace de pompage 19 du carter de pompe 7, 13 et un environnement, le canal de liaison (18) de la bride 15 présentant une zone configurée en labyrinthe 23 qui est agencée à une sortie 17 du carter de pompe 7, 13 et/ou, dans l'espace de pompage 19 du carter de pompe 7, 13, est agencé un rotor de pompe 10 qui peut être entraîné par une unité d'entraînement 2 agencée sur la bride 15, une surface inférieure 24 du canal de liaison 18 étant agencée de manière inclinée par rapport à un plan de rotation 25 du rotor de pompe 10, et la sortie 17 du carter de pompe 7, 13 étant agencée vers l'environnement, à l'état monté en dessous d'une zone 26 du canal de liaison 18 opposée à la sortie 17.
