Abstract
LA INVENCION SE REFIERE A UN CONDUCTO DE DESACOPLE DE PARED ONDULADA FLEXIBLE (1) PARA EL SISTEMA DE ESCAPE DE UN MOTOR DE VEHICULO; EL CONDUCTO ESTA DEFINIDO POR UN ELEMENTO TUBULAR DE PARED CONTINUA FLEXIBLE (2), Y FABRICADO A PARTIR DE UNA HOJA DE ACERO INOXIDABLE (5), LA CUAL SE PLIEGA PARA FORMAR UN CONDUCTO CERRADO Y DEFORMADA AXIALMENTE PARA FORMAR UNA SERIE DE ONDULACIONES CIRCULARES (7) QUE PERMITEN QUE EL CONDUCTO FLEXIONE; EL ELEMENTO TUBULAR (2) ESTA CUBIERTO EXTERNA O INTERNAMENTE CON UNA FUNDA TEJIDA DE ALAMBRE DE ACERO INOXIDABLE (11, 17): EL ELEMENTO TUBULAR, DE ACUERDO CON LA INVENCION, TIENE, EN CADA EXTREMO (3, 4), UN GRUPO DE AL MENOS TRES ONDULACIONES (20, 21, 22) DE DIAMETROS INTERIORES Y/O EXTERIORES CRECIENTES (D 1 , D SUB.2 , D 3 ) PARA DECRECER GRADUALMENTE EN ALTURA HACIA EL EXTREMO RESPECTIVO DEL ELEMENTO TUBULAR; LAS ONDULACIONES (20,21, 22) EN CADA EXTREMO ESTAN SEPARADAS POR ESPACIAMIENTOS (P 1 , P 2 , P 3 ) DIFERENTES UNOS DE OTROS Y DEL ESPACIAMIENTO CONTINUO DE LAS ONDULACIONES INTERMEDIAS (6A); Y LAS ONDULACIONES ASI FORMADAS CONFIEREN MAYOR RIGIDEZ A LOS EXTREMOS DEL CONDUCTO FLEXIBLE EN EL CASO DE ESTRES POR CURVATURA LATERAL, CON EL FIN DE ALCANZAR UN ESTRES SUSTANCIALMENTE UNIFORME A LO LARGO DE LOS MERIDIANOS DE LAS ONDULACIONES.
