Abstract

SOPORTE PARA UN CUERPO PORTADOR METALICO DE CATALIZADOR DE GAS DE ESCAPE Y PROCEDIMIENTO PARA LA FABRICACION, QUE CUYO SOPORTE NO IMPIDE DILATACIONES LONGITUDINALES DEL CUERPO PORTADOR DE CATALIZADOR (1) EN UN TUBO ENVOLVENTE Y QUE EFECTUA ESPECIALMENTE UN AISLAMIENTO TERMICO ENTRE EL CUERPO PORTADOR CATALIZADOR (1) Y EL TUBO ENVOLVENTE (2). PREFERENTEMENTE SE FIJA EL CUERPO PORTADOR DE CATALIZADOR (1) POR MEDIO DE DOS O VARIOS SOPORTES DISTANCIADORES (4A, 4B,4C) EN FORMA DE COLLARINEN EL TUBO ENVOLVENTE (2) A UNA DISTANCIA DE ALGUNOS MILIMETROS. EL INTERSTICIO (8) ESTA RELLENO CON MATERIAL DE FIBRA O UN MATERIAL FLUENTE, POR EJEMPLO, ARENA DE CUARZO, CON LO QUE AMORTIGUAN FUERTEMENTE LAS VIBRACIONES DEL CUERPO PORTADOR DECATALIZADOR (1). DE LOS SOPORTES DISTANCIADORES (4A,4B,4C) QUE ACTUAN SOLAMENTE POCO COMO PUENTES TERMICOS, SOLAMENTE UNO (4A) ESTA CONECTADO FIJO CON EL CUERPO PORTADOR DE CATALIZADOR (1) COMO TAMBIEN CON EL TUBO ENVOLVENTE (2), MIENTRAS QUE LOS DEMAS (4B, 4C) SE DESLIZAN EN FORMA HERMETICA A LO LARGO DEL TUBO ENVOLVENTE (2). EL CUERPO PORTADOR DE CATALIZADDOR (1) FIJADO SEGUN LA PRESENTE INVENCION (1) TIENE DE ESTA MANERA UNA ELEVADA DURACION DE VIDA Y UN BUEN COMPORTAMIENTO DE REACCION.
