Abstract

L'invention concerne un appareil catalytique de traitement de gaz. Un élément catalytique unitaire en matière céramique comportant des passages d'écoulement pour gaz à travers lui est placé à l'intérieur d'un boîtier et l'élément catalytique. Un élément élastique qui est est compressible tant radialement que longitudinalement est placé autour de l'élément catalytique dans ledit espace de manière à maintenir élastiquement l'élément catalytique. Un tampon est placé au moins partiellement dans cet espace et, par exemple, autour de l'élément catalytique aux parties terminales opposées de l'élément catalytique, d'une manière qui comprime longitudinalement l'élément élastique dans une mesure importante pour augmenter la force de serrage exercée sur l'élément catalytique par l'élément élastique et empêcher ainsi un mouvement axial de l'élément catalytique durant son utilisation. Application au traitement des gaz d'échappement des moteurs combustion interne.
