Abstract
LA INVENCION SE REFIERE A UN SISTEMA DE INYECCION DE CARBURANTE PARA MOTORES DE COMBUSTION INTERNA DONDE CON LA AYUDA DE UNA BOMBA A ALTA PRESION SE ENVIA EL CARBURANTE A UN DEPOSITO IGUALMENTE SOMETIDO A ALTA PRESION (6) QUE ALIMENTA VALVULAS DE INYECCION DE CARBURANTE ACCIONADAS ELECTRICAMENTE (9). PARA MANTENER LA ALTA PRESION EN EL INTERIOR DEL DEPOSITO, SE DISPONE UN PRIMER ELEMENTO DE BOMBEO (16) DE CAUDAL VARIABLE QUE ALIMENTA A ESTE CON CARBURANTE, MIENTRAS QUE UN SEGUNDO ELEMENTO DE BOMBEO (17) ENVIA, EN CASO NECESARIO, AL DEPOSITO UN CAUDAL CONSTANTE DE CARBURANTE. DE ESTA FORMA SE OBTIENE UN SISTEMA SENCILLO Y ECONOMICO PARA CONSEGUIR ALTA PRESION EN EL SISTEMA DE INYECCION DE CARBURANTE.
