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 ESTAN CONFIGURADOS EN UNA SOLA PIEZA, DE FORMA QUE NO ES POSIBLE NINGUNA MEDICION DE GAS VARIABLE. PARA ELLO SE CONFIGURA EL NUEVO CUERPO (50) ANTEPUESTO DE LA VALVULA (21) DE INYECCION DE COMBUSTIBLE EN DOS PARTES, ES DECIR A PARTIR DEL CUERPO (51) BASICO Y DE LA PARTE (52) DE APLICACION. CON ELLO RESULTA UNA SEPARACION DE FUNCIONAMIENTO DE LA AFLUENCIA DE GAS Y DE LA MEDICION CORRESPONDIENTE EN CONTRA DE LA ESTANQUEIDAD DE LA VALVULA (1) DE INYECCION DE COMBUSTIBLE HACIA UNA CONDUCCION DE ASPIRACION Y LA SUJECION DEL CUERPO (50) ANTEPUESTO EN LA VALVULA (1) DE INYECCION DE COMBUSTIBLE. RESULTA ADEMAS A PARTIR DE LA CONFIGURACION CONSTRUCTIVA UNA GRAN MULTIPLICIDAD DE VARIANTES, QUE PUEDEN CONSEGUIRSE POR MEDIO DE UNA INTERCAMBIABILIDAD MUY SENCILLA Y DECOSTE ADECUADO EN BASE A LOS SISTEMAS DE CAJAS DE CONSTRUCCION. LA VALVULA DE INYECCION DE COMBUSTIBLE ES APROPIADA ESPECIALMENTE PARA INSTALACIONES DE INYECCION DE COMBUSTIBLE DE MOTORES DE COMBUSTION INTERNA DE ENCENDIDO EXTERIOR ESTANCOS A MEZCLA.
