Abstract

Ce dispositif à catalyseur sert à décontaminer les gaz d'échappement d'un moteur à combustion interne. Il comprend un boîtier 1 fermé par des plaques d'extrémité 3 et présentant une tubulure d'entree de gaz 5 et une tubulure de sortie de gaz 6. Ce boîtier contient un récipient 7, dans lequel est disposé le catalyseur, ayant en section droite la forme d'une couronne et possédant des parois 8 perforées. Selon l'invention, au moins une extrémité axiale du récipient intérieur 7 est montée coulissante dans la région d'au moins une plaque d'extrémité 3 afin de permettre des mouvements axiaux et radiaux relatifs du récipient intérieur et du boîtier 1 et d'éviter ainsi la déformation ou la détérioration de parties du dispositif sous l'effet des différences de température et de dilatation des parties du dispositif.
