Abstract

LA INVENCION SE REFIERE A UN CODO TUBULAR (CODO 1 DE TUBO DOBLE) PARA MOTORES DE COMBUSTION INTERNA CON UN CUERPO (2,3) TUBULAR FABRICADO MEDIANTE UN PROCESO DE CONFORMACION. SU EXTREMO ABIERTO ES CONECTABLE CON LAS ABERTURAS (4 HASTA 7) DE UNA BRIDA (8) EN EL LADO DEL MOTOR. LA PARED DEL CUERPO TUBULAR MUESTRA UNA ABERTURA COLECTORA QUE ESTA DIRIGIDA A UNA BRIDA (11) EN EL LADO DE ESCAPE. PARA LA ELABORACION DE LA RESISTENCIA DE DURACION DE UN CODO TUBULAR DE ESTE TIPO SE PROPONE, QUE EL CUERPO (2,3) TUBULAR SEA ELABORADO DE UNA SOLA PIEZA CON ESPESORES DE PARED DIFERENTES POR MEDIO DE UNA CONFORMACION DE ALTA PRESION INTERNA. PARA ELLO A PARTIR DE LA ABERTURA COLECTORA PARA EL ORIFICIO DE LAS BRIDAS (9.10) EN EL LADO DE ESCAPE SE FORMAN CONDUCTOS TUBULARES DE GUIA DE FORMA DIRECTA.
