Abstract

UN TUBO DE ESCAPE DE UN MOTOR CON UNA DISTANCIA ENTRE ELECTRODOS, ACUSTICAMENTE MEJORADO (10) QUE TIENE UN CONDUCTO DE ESCAPE METALICO, DE DISTANCIA ENTRE ELECTRODOS, DE DOBLE PARED DE UNA ENVOLTURA EXTERIOR (12) Y UN REVESTIMIENTO INTERIOR DELGADO (14), EN DONDE LA ENVOLTURA (12) TIENE AL MENOS UN ORIFICIO DE ENTRADA DEL GAS DE ESCAPE Y UN ORIFICIO DE SALIDA DEL GAS DE ESCAPE, EL REVESTIMIENTO (14) TIENE AL MENOS UN ORIFICO DE ENTRADA Y UN ORIFICIO DE SALIDA, EN DONDE EL ORIFICIO DE ENTRADA DE LA ENVOLTURA Y EL ORIFICIO DE ENTRADA DEL REVESTIMIENTO SE ENCUENTRAN ADYACENTES ENTRE SI, EL REVESTIMIENTO (14) QUEDA ASEGURADO A LA ENVOLTURA (12) POR LA PARTE ADYACENTE AL ORIFICIO DE ENTRADA DE LA ENVOLTURA Y AL ORIFICIO DE ENTRADA DEL REVESTIMIENTO, EL ORIFICIO DE SALIDA DEL REVESTIMIENTO PUEDE QUEDAR OPCIONALMENTE ACOPLADO A LA ENVOLTURA (12) Y EL REVESTIMIENTO (14) PUEDE POR EL CONTRARIO ESTAR SEPARADO DE LA ENVOLTURA (12) POR TODO SU LARGO PARA FORMAR UNA DISTANCIA ENTRE ELECTRODOS CONTINUA DEL ORIFICIO DE ENTRADA DEL REVESTIMIENTO AL ORIFICO DE SALIDA DEL REVESTIMIENTO, Y UN MODELO DE SALIENTES DE INDENTACION (20,22) SALEN ENTRANDO O SALIENDO DE LA ENVOLTURA POR SUSTANCIALMENTE TODA LA ENVOLTURA ANTEDICHA (12), Y CADA SALIENTE DE INDENTACION (20,22) SALE ACERCANDOSE O SEPARANDOSE DEL REVESTIMIENTO (14) Y TERMINA CERCA DEL REVESTIMIENTO (14) DE FORMA SEPARADA Y SIN QUEDAR ACOPLADO AL REVESTIMIENTO (14) PARA ASI MANTENER LA DISTANCIA ENTRE ELECTRODOS CONTINUA. OPCIONALMENTE, EL REVESTIMIENTO (14) PUEDE TENER UN TIPO DE SALIENTES DE INDENTACION QUE SALEN HACIA ADENTRO O HACIA AFUERA, EN DONDE EN ESTE ULTIMO CASO, TERMINAN CERCA DE LA ENVOLTURA (12) PERO SIN QUEDAR ACOPLADOS A ESTA Y DEJAN UNA DISTANCIA ENTRE ELECTRODOS POR TODO EL LARGO DE LA MISMA.
