Abstract

Les pompes à liquide de refroidissement pour moteurs à combustion interne, comprenant un arbre d'entraînement (18), une roue mobile de pompe à liquide de refroidissement (20), laquelle est disposée fixement sur l'arbre d'entraînement (18) au moins de manière solidaire en rotation et par le biais de laquelle du liquide de refroidissement peut être refoulé, et un tiroir de régulation (58) réglable par le biais duquel une section transversale d'écoulement d'un interstice annulaire (62) entre une sortie (64) de la roue mobile de pompe à liquide de refroidissement (20) et le canal de refoulement (12) environnant peut être réglée sont connues. L'invention vise à obtenir une étanchéification fiable des deux chambres de refoulement opposées (92, 94) en particulier en cas de réglage purement hydraulique. À cet effet, le tiroir de régulation (58) comprend une paroi périphérique (84) intérieure cylindrique creuse, sur le côté intérieur radial de laquelle est ménagée une rainure radiale (86) dans laquelle une bague d'étanchéité (88) est disposée, et une paroi périphérique (60) extérieure cylindrique creuse, sur le côté extérieur radial de laquelle est ménagée une rainure radiale (74) dans laquelle une bague d'étanchéité (76) est disposée, les deux parois périphériques (60, 84) étant reliées l'une à l'autre par le biais d'un fond (80).
