Abstract

Dispositif de purification de gaz d’échappement comprenant une cartouche amovible, et ligne d’échappement comprenant un tel dispositif Ce dispositif de purification de gaz d’échappement (24) comprend un logement (30) comportant une conduite tubulaire de gaz d’échappement (40) définissant un espace de réception (46), et une cartouche (32) montée de manière amovible dans ledit espace de réception (46). Le dispositif de purification (24) comprend également un tube flexible (122) monté entre la conduite tubulaire (40) et la cartouche (32), ledit tube flexible (122) étant compressible et/ou extensible suivant l’axe (A-A’) de l’espace de réception (46). Un premier des éléments parmi la conduite tubulaire (40) et la cartouche (32) définit un épaulement annulaire primaire (114, 174) contre lequel une première extrémité axiale (126, 128) du tube flexible (122) est en butée, la deuxième extrémité axiale (126, 128) du tube flexible (122) étant fixée au deuxième élément parmi la conduite tubulaire (40) et la cartouche (32).
