Abstract

LA DISPOSICION DE VALVULA PARA UN RETROCESO DE GASES DE ESCAPE EN UN MOTOR DE COMBUSTION INTERNA MUESTRA UNA VALVULA (1) CONTROLADA, CUYO PLATO (1A) DE VALVULA ACCIONA CONJUNTAMENTE CON UN ASIENTO (2) DE VALVULA EN UNA CARCASA (7B). LA ENTRADA DE GASES DE ESCAPE DE LA CARCASA DE VALVULA ESTA UNIDA A TRAVES DE UN TUBO (7) DE RETROCESO DE GASES DE ESCAPE CON EL LADO DE GAS DE LA SALIDA DE GASES A TRAVES DE UN TUBO (16) DE UNION UNIDO CON LA CARA DE ASPIRACION DEL MOTOR DE COMBUSTION INTERNA. LA CARCASA DE VALVULA ESTA CONFIGURADA A TRAVES DE UN TRAMO (7B) EXTREMO DEL TUBO (7) DE RETROCESO DEL GAS DE ESCAPE Y ASIMISMO A TRAVES DEL ASIENTO (2) DE VALVULA MEDIANTE UNA ESTRANGULACION (8) FORMADA EN EL TRAMO EXTREMO. LA PIEZA (9) TUBULAR DEL TRAMO (7B) EXTREMO QUE SE CONECTA EN LA ESTRANGULACION (8) SOPORTA LA CARCASA (3) DE ACCIONAMIENTO DE AJUSTE. LA PIEZA (9) TUBULAR ESTA PROVISTA LATERALMENTE CON UNA ABERTURA (14) QUE FORMA LA SALIDA DE GAS Y EL TUBO (16) DE UNION ESTA SOLDADO A LA PIEZA (9) TUBULAR EN LA ZONA DE ESTA ABERTURA (14).
