Title (EN) HYDRAULIC PUMP FOR A HYDRAULIC CONNECTION INTERFACE OF A CLUTCH MECHANISM
(FR) POMPE HYDRAULIQUE POUR INTERFACE DE CONNEXION HYDRAULIQUE D'UN MECANISME D'EMBRAYAGE
Abstract:
(EN) The invention relates to a hydraulic pump (6, 7) for a clutch mechanism (1) of a vehicle transmission, said hydraulic pump (6, 7) comprising a body (60, 70) provided with a chamber (61, 71), an inlet port (62, 72) through which a hydraulic fluid can enter the chamber (61, 71), and an outlet port (63, 73) through which the hydraulic fluid can leave the chamber (61, 71), said chamber (61, 71) receiving at least one water wheel of the hydraulic pump (6, 7), the inlet port (62, 72) and the outlet port (63, 73) each opening into the chamber (61, 71) of the body (60, 70). According to the invention, the body (60, 70) of the hydraulic pump (6, 7) is delimited by an outer edge (80) on which at least one peripheral groove (81, 82) is formed, said groove being designed to receive a gasket (83, 84) that is intended to provide contact sealing between the body (60, 70) of the hydraulic pump (6, 7) and a hydraulic connection interface (4) of the clutch mechanism (1).
(FR) L'invention concerne une pompe hydraulique (6, 7) pour mécanisme d'embrayage (1) d'une transmission de véhicule, la pompe hydraulique (6, 7) comprenant un corps (60, 70) dans lequel sont formées une chambre (61, 71), une ouverture d'entrée (62, 72) par laquelle un fluide hydraulique est apte à entrer dans la chambre (61, 71), et une ouverture de sortie (63, 73) par laquelle le fluide hydraulique est apte à sortir de la chambre (61, 71), la chambre (61, 71) recevant au moins une roue hydraulique de la pompe hydraulique (6, 7), l'ouverture d'entrée (62, 72) et l'ouverture de sortie (63, 73) débouchant chacune sur la chambre (61, 71) du corps (60, 70), le corps (60, 70) de la pompe hydraulique (6, 7) est délimité par un contour extérieur (80) sur lequel est formée au moins une rainure périphérique (81, 82) configurée pour recevoir un joint (83, 84), le joint (83, 84) étant destiné à assurer une étanchéité de contact entre, d'une part, le corps (60, 70) de la pompe hydraulique (6, 7) et, d'autre part, une interface de connexion hydraulique (4) du mécanisme d'embrayage (1),
