Abstract

L'invention porte sur un filtre pour l'air d'admission, qui sert à purifier l'air destiné à des moteurs à combustion interne, en particulier dans des véhicules. A cette fin, le filtre pour l'air d'admission comporte un bâti (10) pouvant être ouvert, avec un orifice d'entrée (14) et un orifice de sortie (15). Entre l'orifice d'entrée (14) et l'orifice de sortie (15) est disposé un élément filtrant principal (17), fermé et annulaire, et un élément secondaire (31), fermé et annulaire. L'élément secondaire (31) est relié à l'orifice de sortie (15), de sorte que, lors du remplacement de l'élément filtrant principal (17), aucune saleté ne peut pénétrer dans l'orifice de sortie (15). Sur le côté frontal, opposé à l'orifice de sortie (15), il est prévu, entre l'élément secondaire (31) et l'élément filtrant principal (17), un dispositif de centrage (29, 30, 40, 41, 42), qui sert à fixer la position de l'élément secondaire (31) à l'intérieur de l'élément filtrant principal (17). On empêche ainsi des mouvements relatifs entre l'élément filtrant principal (17) et l'élément secondaire (31).
