Abstract
L'invention propose un dispositif de post-traitement (10) de gaz d'échappement de moteur à combustion de véhicule automobile comportant une enceinte délimitée par une paroi tubulaire définissant une chambre tubulaire interne, un élément déflecteur (16) agencé à l'intérieur de l'enceinte, sensiblement au centre de la chambre tubulaire, au moins deux bras (36) de fixation de l'élément déflecteur (16) dont chacun est d'orientation globalement radiale et comporte une extrémité radiale interne (38) fixée à l'élément déflecteur (16) et une extrémité radiale externe (40) fixée à la face interne concave (30) de la paroi tubulaire, caractérisé en ce qu'il comporte au moins un bras de fixation (36) déformable dont la longueur est supérieure à la distance radiale (DR) séparant son extrémité radiale interne (38) de la face interne concave (30) de la paroi tubulaire.The invention provides an after-treatment device (10) for exhaust gases from a combustion engine of a motor vehicle comprising an enclosure delimited by a tubular wall defining an internal tubular chamber, a deflector element (16) arranged inside. of the enclosure, substantially in the center of the tubular chamber, at least two arms (36) for fixing the deflector element (16) each of which is of generally radial orientation and has an internal radial end (38) fixed to the deflector element (16) and an external radial end (40) fixed to the concave internal face (30) of the tubular wall, characterized in that it comprises at least one deformable fixing arm (36) whose length is greater at the radial distance (DR) separating its internal radial end (38) from the concave internal face (30) of the tubular wall.
