Abstract

L'invention concerne un filtre de protection de l'environnement (10) pourvu d'un tuyau d'entrée de fluide (12) comprenant une entrée d'air forcé (16) traversant une coque extérieure (18) s'étendant axialement et pourvue d'un couvercle (20) d'extrémité proximale et d'un couvercle (22) d'extrémité distale. Le tuyau d'entrée (12) comprend un tuyau intérieur (32) pourvu de perforations (34). Une première chicane perforée (28) est suivie d'une seconde chicane imperméable (30), lesdites chicanes entourant le tuyau à perforations (32) qui traverse la coque extérieure (18). La coque extérieure (18) est remplie d'un matériau filtrant (36) placé entre ladite coque et le tuyau à perforation (32). Ledit tuyau à perforations (32) est pourvu d'éléments d'obturation (40), situés au même niveau que les chicanes perforées (28). Le filtre de protection de l'environnement (10) est pourvu d'un tuyau de sortie (8) qui s'étend depuis le couvercle d'extrémité distale (22).
