Abstract

Ce convertisseur comprend un catalyseur monolithique 6 enfermé dans la chambre de catalyse d'une coquille 7 comprenant en outre une chambre d'entrée 17 raccordée à deux tuyaux d'échappement amont 2 et une chambre de sortie raccordée à un tuyau d'échappement avaL Le catalyseur est maintenu élastiquement dans la coquille 7 par un grillage métallique 23 et deux anneaux de grillage 24 et 25 formant l'espace entre le catalyseur 6 et la coquille 7. Un organe d'étanchéité 22, formé d'un collet en tôle qui s'emboîte sur l'élément catalyseur 6 est monté dans la chambre d'entrée et est éventuellement fixé sur le catalyseur 6 par une couche de ciment réfractaire. Cet organe 22 comporte une partie conique légèrement élastique contre laquelle une moulure 28 de la chambre d'entrée de la coquille est pressée. L'anneau de grillage 24 est interposé entre un épaulement 22b de l'organe d'étanchéité 22 et un épaulement 26 de la coquille.
