Title (EN) VACUUM PUMP FOR A MOTOR VEHICLE
(FR) POMPE À VIDE POUR UN VÉHICULE À MOTEUR
(DE) VAKUUMPUMPE FÜR EIN KRAFTFAHRZEUG
Abstract:
(EN) The invention relates to a vacuum pump (10) for a motor vehicle, comprising a housing part (12) which partially encloses a pump chamber (14), wherein the housing part (12) has an inlet channel (20) that leads into a pump chamber inlet opening (22) and has a receptacle (24) upstream of the inlet opening (22) for a connection piece (30), wherein the connection piece (30) comprises a snap ring annular groove (26) on the outside, and the connection piece holder (24) comprises a corresponding snap ring annular groove (28) on the inside, a non-closed snap ring being seated in the annular grooves (26,28).
(FR) Pompe à vide (10) pour un véhicule à moteur, qui comporte une partie carter (12) entourant en partie une cavité de pompe (14), la partie carter (12) présentant un canal d’entrée (20) qui débouche dans un orifice d’entrée (22) de la cavité de pompe et qui comporte en amont de l’orifice d’entrée (22) un évidement récepteur (24) pour une tubulure de raccordement (30), ladite tubulure de raccordement (30) comportant à l’extérieur une rainure annulaire (26) pour un clip de retenue et l’évidement récepteur (24) pour la tubulure de raccordement comportant à l’intérieur une rainure annulaire (28) pour le clip de retenue correspondante. Un clip de retenue (29) non fermé est installé dans les rainures annulaires (26, 28).
(DE) Vakuumpumpe (10) für ein Kraftfahrzeug mit einem Gehäuseteil (12), das einen Pumpraum (14) teilweise einschließt, wobei das Gehäusetell (12) einen Einlasskanal (20) aufweist, der in eine Pumpraum-Einlassöffnung (22) mündet und stromaufwärts der Einlassöffnung (22) eine Aufnahme (24) für einen Anschlussstutzen (30) aufweist, wobei der Anschlussstutzen (30) außenseitig eine Sprengring-Ringnut (26) und die Anschlussstutzen-Aufnahme (24) innenseitig eine korrespondierende Sprengring-Ringnut (28) aufweist, und ein nicht-geschlossener Sprengring (29) in den Ringnuten (26,28) sitzt.
