Abstract

EN VALVULAS DE INYECCION CONOCIDAS SE APLICAN AGUJEROS DE INYECCION MEDIANTE PROCESO DE ESTAMPACION EN UN DISCO AGUJEREADO, CON LO CUAL LA ESTAMPACION SE OBTIENE EN IGUALES DIRECCIONES PARA UNA CORRIENTE DE MEDIO QUE APARECE A SU TRAVES MAS TARDE POR MEDIO DEL AGUJERO DE INYECCION DE SALIDA. LOS DISCOS AGUJEREADOS MUESTRAN CON ELLO UNA RESISTENCIA A LA TRACCION DESDE 400 HASTA 600 N/MM2. CON ELLO SE OBTIENE EN PROCESOS DE ESTAMPACION DE AGUJEROS DE INYECCION LA APARICION DE FENOMENOS NEGATIVOS EN LOS BORDES DEL AGUJERO COMO ADMISION DE ESTAMPACION NO DESEADA Y REBABAS. EN LA NUEVA VALVULA DE INYECCION SE UTILIZA UN DISCO (21) AGUJEREADO A BASE DE UN MATERIAL DE MAYOR DUREZA. EL DISCO (21) AGUJEREADO MUESTRA PROPIAMENTE UNA RESISTENCIA A LA TRACCION MAYOR DE 800 N/MM2. LA FRAGILIDAD MAYOR QUE APARECE EN LA ESTAMPACION DEL MATERIAL NO TIENE NINGUN DESARROLLO NEGATIVO, YA QUE EL DISCO (21) AGUJEREADO ESTA CONFIGURADO DE TAL MODO EN LA VALVULA DE INYECCION, QUE LA DIRECCION DE LA CORRIENTE DE MEDIO ES EXACTAMENTE CONTRARIA A LA DIRECCION DE ESTAMPACION. LA VALVULA DE INYECCION ES APROPIADA ESPECIALMENTE PARA INSTALACIONES DE INYECCION FINA DE COMBUSTIBLE DE MOTORES DE COMBUSTION INTERNA DE ENCENDIDO EXTERIOR CON MEZCLA COMPRIMIDA.
