Abstract

EL TUBO INTERIOR (1) DE UN SILENCIADOR PREVIO QUE FORMA EL RAMAL DE GASES DE ESCAPE ENTRE MOTOR Y CATALIZADOR DE UN AUTOMOVIL ESTA RODEADO POR EL TUBO ENVOLVENTE (3) COMO TUBO PORTANTE DEJANDO UN RESQUICIO ANULAR DE AIRE (2) Y LLEVADO EN UN EXTREMO (4,6) CON ASIENTO CORREDIZO AL TUBO ENVOLVENTE (3). EL ASIENTO CORREDIZO ESTA FORMADO MEDIANTE ELEMENTOS DISTANCIADORES QUE GARANTIZAN UNA MOVILIDAD ANGULAR ADICIONAL ENTRE TUBO INTERIOR (2) Y TUBO ENVOLVENTE (3) EN LA ZONA DEL ASIENTO CORREDIZO. AQUI, LOS ELEMENTOS DISTANCIADORES HACEN CONTACTO EN EL LADO CONCAVO (12) DE UN CUERPO ANULAR (13) QUE PRESENTA LA SECCION APROXIMADA DE UNA CANALETA. EL CUERPO ANULAR (13) ESTA FIJADO CON EL FONDO (16) ENCARADO A LOS ELEMENTOS DISTANCIADORES, A UNA PARED DEL TUBO INTERIOR (1) QUE LIMITA CON EL RESQUICIO ANULAR DE AIRE.
