Abstract

CE CONVERTISSEUR CATALYTIQUE COMPREND UNE ENVELOPPE EXTERIEURE EN TOLE QUI RENFERME DEUX LITS POUR CATALYSEUR 16, 17, EN TOLE. DES ETAIS 110 TRAVERSENT DES TROUS ALIGNES DES ELEMENTS INTERIEURS 35, 36 DES LITS, DES ELEMENTS EXTERIEURS 32, 33 DE CES LITS ET DES ELEMENTS 11 ET 12 DE L'ENVELOPPE POUR RENFORCER CES ELEMENTS ET LES MAINTENIR A L'ECARTEMENT VOULU. LES ELEMENTS INTERIEURS 35 ET 36 DES LITS PRESENTENT L'UN, DES TROUS ET, LE DEUXIEME, DES COLLETS ENFILES DANS CES TROUS ET RABATTUS SUR LEURS BORDS DE SORTE QUE CES ELEMENTS SONT SUPERPOSES CORRECTEMENT AVANT L'ASSEMBLAGE DANS LE CONVERTISSEUR. LES ELEMENTS INTERIEURS 35 ET 36 ET LES ELEMENTS EXTERIEURS 32 ET 33 DES LITS SONT MAINTENUS EN BAS PAR UNE PARTIE ELARGIE DE L'ETAI ET EN HAUT PAR UNE DOUILLE 128 RAPPORTEE AUTOUR DE L'ETAI. LA LIAISON ET L'ECARTEMENT SONT ASSURES PAR SOUDAGE DE RONDELLES 146 SUR LES EXTREMITES DES ETAIS 110.
