Abstract

LA INVENCION SE REFIERE A UNA REALIZACION DE DISPOSICION ESTANCA AL GAS AISLANTE ELECTRICA PARA AL MENOS UN CONDUCTOR (5,6) ELECTRICO A TRAVES DE UNA CUBIERTA (1,2) METALICA DE UN SISTEMA DE EXHAUSTACION DE UN MOTOR DE COMBUSTION INTERNA, ESPECIALMENTE DE UN CONVERTIDOR (11) CATALITICO CALENTABLE ELECTRICAMENTE, DONDE LA CUBIERTA (1,2) DISPONE DE TABULACIONES (3,4) EN LA REGION DE LA REALIZACION DE DISPOSICION ESTANCA ENTRE LAS CUALES CIRCULA EL CONDUCTOR ELECTRICO, ESTANDO DIVIDIDA LA REALIZACION EN DOS SECCIONES (A,B) UNA DETRAS DE OTRA. LA PRIMERA DE LAS CUALES (A) QUE ESTA MAS CERCA AL SISTEMA (11) DE GASES DE EXHAUSTACION, ESTA DISEÑADA PARA SER AISLADA ELECTRICAMENTE Y RESISTENTE A TEMPERATURAS DE HASTA 1.300 QUE DISPONGA DE ESTANQUEIDAD AL GAS COMPLETA, MIENTRAS QUE LA SEGUNDA SECCION (B) MAS ALEJADA CON RESPECTO AL SISTEMA (11) DE GASES DE EXHAUSTACION ESTA DISEÑADA COMO UNA REALIZACION AISLANTE ESTANCA AL GAS Y CON AISLAMIENTO ELECTRICO PARA TEMPERATURAS DE HASTA 500 MERA SECCION (A) ES UN MATERIAL (9) CERAMICO, CON PREFERENCIA ARCILLA COMPRIMIDA. UN MATERIAL (10) ELASTICO-PLASTICO SIMILAR AL UTILIZADO POR EJEMPLO PARA LAS JUNTAS DE CULATA PUEDE SER UTILIZADO COMO MATERIAL DE AISLANTE Y DE SELLADO EN LA SEGUNDA SECCION (B). LA REALIZACION ESTANCA AL GAS PUEDE SER UTILIZADA DE FORMA ECONOMICA EN CONVERTIDORES CATALITICOS CALENTABLES ELECTRICAMENTE EN VEHICULOS A MOTOR.
