Abstract

L'invention concerne une pompe à engrenages à denture intérieure (1) en tant que pompe de refoulement pour un circuit de freinage d'un véhicule. L'invention propose de réaliser une pièce intercalaire (9) dotée de deux éléments pliés (10, 11) en tôle qui sont reliés par un élément d'étanchéité axial (14) fixé par vulcanisation et, vu de côté, en forme de U. L'élément d'étanchéité axial (14) améliore un rendement de la pompe à engrenages à denture intérieure (1) et permet des tolérances de fabrication plus importantes.
