Abstract

L'invention concerne un dispositif de filtration (10) d'un fluide, notamment du gaz, de préférence de l'air, du carburant, de l'huile, de l'eau ou une solution d'eau et d'urée, particulièrement d'un moteur à combustion interne, particulièrement d'un véhicule automobile, comprenant un boîtier de filtre (12) qui peut être ouvert et un élément porteur (34) pour au moins un élément filtrant (40). Ledit élément filtrant (40) possède au moins un soufflet de filtre (42). Ledit élément filtrant (40) est disposé dans le boîtier de filtre (12). Au moins un raccord d'entrée de fluide (20) est relié à un côté fluide brut (66) dudit élément filtrant (40). Au moins un raccord de sortie de fluide (26) est relié à un côté fluide purifié (52) dudit élément filtrant (40). Au moins un élément porteur (34), séparé au moins initialement du boîtier de filtre (12), supporte au moins l'un des éléments filtrants (40) dans le boîtier de filtre (12). Au moins l'un des raccords de filtre (26) est relié à demeure audit élément porteur (34).
