Abstract

SE DESCRIBE UNA VALVULA, EN PARTICULAR UNA VALVULA DE INYECCION DE COMBUSTIBLE PARA SISTEMAS DE INYECCION DE COMBUSTIBLE DE MOTORES DE COMBUSTION INTERNA, QUE TIENE UNA SUPERFICIE (17) DE ASIENTO DE VALVULA, DISEÑADA SOBRE UN CUERPO (14) DE ASIENTO DE VALVULA, QUE COOPERA CON UN CUERPO (8) DE CIERRE DE VALVULA, CAPAZ DE SER ACCIONADO PARA CERRAR FUERTEMENTE LA VALVULA, ASI COMO UN DISCO PERFORADO DE INYECCION (15) CON AL MENOS UN ORIFICIO DE INYECCION (18). SEGUN LA REALIZACION EXPUESTA, EL CUERPO (14) DEL ASIENTO DE LA VALVULA Y EL DISCO PERFORADO DE INYECCION (15) ESTAN REALIZADOS COMO UNA SOLA PIEZA PLANA Y DEFORMABLE (16). LA PIEZA (16) ESTA CONFIGURADA A MANERA DE UN RECIPIENTE, POR LO QUE LA ZONA DE LA SUPERFICIE (17) DEL ASIENTO DE LA VALVULA SE COLOQUE ESTRECHAMENTE SOBRE EL CUERPO (8) DEL CIERRE DE VALVULA NO ACCIONADO, EN EL ESTADO CERRADO DE LA VALVULA (1), Y EN UNA ZONA SITUADA AGUAS ABAJO DE LA SUPERFICIE (17) DEL ASIENTO DE LA VALVULA FORMA EL DISCO PERFORADO (15) DE INYECCION, CON AL MENOS UN ORIFICIO DE INYECCION (18).
