Abstract

L'invention concerne une pompe à engrenages intérieurs (1) doté d'un ressort à branches en tant que pièce de séparation (7) entre un côté admission (8) et un côté refoulement (9). Selon l'invention, des zones médianes (a, b) de branches (13, 14) de la pièce de séparation (7) sont conçues plus épaisses que des extrémités libres et des transitions (c, d) en direction d'un élément de liaison (15) de la pièce de séparation (7), de manière que les branches (13, 14) reposent jusqu'à leurs extrémités libres avec une précontrainte importante au niveau de sommets de dents de roues dentées (2, 3) de la pompe à engrenages intérieurs (1). Des courbures marquées sont prévues au niveau des transitions (c, d) entre les branches (13, 14) et l'entretoise (15) de manière à réduire les tensions mécaniques dans la zone de l'entretoise (15) de la pièce de séparation (7).
