Abstract

EN LOS MODELOS ANTERIORES DE VALVULAS DE INYECCION DE COMBUSTIBLE, EL RECORRIDO DE LA AGUJA DE LA VALVULA SE PODIA AJUSTAR A BASE DE OPRIMIR UN EXTREMO DEL CUERPO DE LA BOQUILLA DE LA VALVULA POR EJEMPLO O DE VARIAR LA PROFUNDIDAD DE PENETRACION DEL CUERPO DEL ASIENTO DE LA VALVULA INSERTADO EN LA APERTURA LONGITUDINAL DEL SOPORTE DEL ASIENTO DE LA VALVULA Y POR CONSIGUIENTE ASEGURADO RIGIDAMENTE AL SOPORTE DEL ASIENTO DE LA VALVULA. SIN EMBARGO, ESTE METODO DE AJUSTE NO ES POSIBLE CON VALVULAS MONTADAS. SI EL CUERPO DEL ASIENTO DE LA VALVULA SE PRESIONA E INTRODUCE EN LA APERTURA LONGITUDINAL, EXISTE EL PELIGRO DE QUE SE FORME UN CORTE. EN LA NUEVA VALVULA DE INYECCION DE COMBUSTIBLE, UN MONTAJE DE VALVULA QUE COMPRENDE EL CUERPO DEL ASIENTO DE LA VALVULA (18) Y EL CUERPO PERFORADO (22) UNIDO A ELLA SE INSERTA EN LA APERTURA LONGITUDINAL (3) DEL SOPORTE DEL ASIENTO DE LA VALVULA (1) Y SE ASEGURA RIGIDAMENTE A ELLA, DETERMINANDO LA PROFUNDIDAD DE LA INSERCION EL AJUSTE INICIAL DEL RECORRIDODE LA AGUJA DE LA VALVULA. EL AJUSTE EXACTO DEL RECORRIDO DE LA AGUJA SE PUEDE EFECTUAR CON LA VALVULA MONTADA A BASE DE DOBLAR LA PARTE DE LA VALVULA QUE SE ENCUENTRA ENTRE LOS PUNTOS DE ACOPLAMIENTO (24, 30) DEL CUERPO PERFORADO (22) AL SOPORTE DEL ASIENTO DE LA VALVULA. LA VALVULA DE INYECCION DE COMBUSTIBLE QUE SE PROPONE Y EL METODO PARA SU FABRICACION SON PARTICULARMENTE UTILES PARA UTILIZARLOS EN SISTEMAS DE INYECCION DE COMBUSTIBLE EN MOTORES DE IGNICION POR CHISPA DE COMPRESION DE LA MEZCLA.
