Abstract

L'invention concerne un élément filtrant (70) comprenant un milieu filtrant (12) plié en étoile qui entoure un axe longitudinal (14) de manière annulaire, une première plaque terminale (20) qui étanchéifie une première face frontale (18) du milieu filtrant (12), une deuxième plaque terminale (24) qui étanchéifie une deuxième face frontale (22) du milieu filtrant (12), un tuyau central (30) qui s'étend de la première plaque terminale (20) à la deuxième plaque terminale (24), une structure de fixation (36) comportant au moins un élément de fixation (38) axial et au moins une butée rotative (40) faisant saillie par rapport à la première plaque terminale (20) à l'opposé du milieu filtrant (12) pour fixer l'élément filtrant (10) sur un premier élément de boîtier (76). Cette invention concerne en outre un filtre à liquide (68) comprenant un tel élément filtrant (70) et un boîtier de filtre (72), un premier élément de boîtier (76) comportant une structure de maintien (75) sur laquelle l'élément filtrant (70) est maintenu au moyen de la structure de fixation (36).
