Title
(EN) BRAKE BOOSTER WITH SEAL JOINT
(FR) SERVOFREIN AVEC JOINT D'ETANCHEITE
Abstract
(EN)
The invention concerns brake booster wherein to solve the problem of passing a cranked part (15) at right angle (16) through an orifice (21) of a joint (19) said joint (19) comprises a deformable notch (20). The sealing condition of the joint (19) and cranked part (15) system is thereby ensured by the presence of fir-shaped protuberances on the base (26) of the bent part (15).
(FR)
Pour résoudre un problème de passage d'une pièce coudée (15) selon un angle droit (16) au travers d'un orifice (21) d'un joint (19), on prévoit que ce joint (19) comporte une encoche (20) déformable. L'étanchéité du système joint (19) et pièce (15) coudée est alors assurée grâce à la présence de sapins sur le culot (26) de la pièce (15) coudée.
