Abstract

EN VALVULAS DE INYECCION DE COMBUSTIBLE CONOCIDAS SE CONSIGUE LA AFLUENCIA DE GAS EN UN CUERPO ANTEPUESTO POR MEDIO DE CANALES DE AFLUENCIA DE GAS, QUE ESTAN DIRIGIDOS SOBRE EL COMBUSTIBLE EN UNA ABERTURA CENTRAL. ESTOS CUERPOS ANTEPUESTOS NO PERMITEN LA OBTENCION DE UNA CORRIENTE DE AFLUENCIA DE LOS GASES DIRIGIDA DE FORMA ENFOCADA SOBRE EL COMBUSTIBLE. PARA ELLO EL NUEVO CUERPO (50) ANTEPUESTO DE LA VALVULA (1) DE INYECCION DE COMBUSTIBLE SE CONFIGURA AL MENOS A PARTIR DEL CUERPO (51) BASICO Y DE LA PARTE (52) DE APLICACION, QUE LIMITAN ENTRE ELLOS LOS CANALES (84) DE AFLUENCIA DE GAS Y EL GAS DE FORMA CONJUNTA SE DIRIGE DE MANERA ENFOCADA HACIA EL COMBUSTIBLE INYECTADO. EL CUERPO (50) ANTEPUESTO PERMITE UNA SEPARACION DE OPERACION DE LA AFLUENCIA DE GAS Y DE LA MEDIDA DE GAS CONTRA LA ESTANQUEIDAD DE LA VALVULA (1) DE INYECCION DE COMBUSTIBLE PARA OBTENER UNA CONDUCCION DE ASPIRACION DE GAS Y LA ASPIRACION Y LA SUJECION DEL CUERPO (50) ANTEPUESTO EN LA VALVULA (1) DE INYECCION DE COMBUSTIBLE. RESULTA ADEMAS DE UNA CONFIGURACION CONSTRUCTIVA UNA GRAN MULTIPLICIDAD DE VARIANTES, QUE PUEDEN CONSEGUIRSE CON UNA CAPACIDAD DE INTERCAMBIO DE MODO SENCILLO Y CON COSTE ADECUADO EN BASE A SISTEMA DE CAJAS DE CONSTRUCCION. LA VALVULA DE INYECCION DE COMBUSTIBLE ES APROPIADA ESPECIALMENTE PARA INSTALACIONES DE INYECCION DE COMBUSTIBLE DE MOTORES DE COMBUSTION INTERNA CON ENCENDIDO EXTERIOR DE MEZCLA ESTANCA.
