Abstract

UN INYECTOR DE COMBUSTIBLE (1) TIENE UN CONDUCTO DE COMBUSTIBLE DE PASO (6) QUE SE ABRE EN UNA BOQUILLA (7). UN RESORTE DE COMPRESION (17) ACCIONA UN DESLIZADOR DE VALVULA LONGITUDINALMENTE DESPLAZABLE (13) EN LA DIRECCION DE CIERRE. UN PRIMER PISTON (21) EN UN EXTREMO DEL RESORTE DE COMPRESION DELIMITA, JUNTO CON UN COMPONENTE ESTACIONARIO (9), UNA PRIMERA CAMARA DE PRESION (28) QUE COMUNICA CON EL CONDUCTO DE COMBUSTIBLE (6) A TRAVES DE UN CANAL (24). UNA SEGUNDA CAMARA DE PRESION (34) ESTA DELIMITADA POR EL PRIMER PISTON Y UN SEGUNDO PISTON (29). CUANDO EL PRIMER PISTON ES PRESIONADO DESDE UNA POSICION EXTREMA CON UN VOLUMEN MINIMO EN LA CAMARA POR LA PRESION DE COMBUSTIBLE EN LA PRIMERA CAMARA DE PRESION, SE ABRE UNA CONEXION DE FLUJO (35) ENTRE LAS DOS CAMARAS DE MODO QUE LA PRESION ES ESTABLECIDA EN LA SEGUNDA CAMARA DE PRESION. LA PRESION ESTABLECIDA EN LAS CAMARAS GENERA UNA CARGA AUTOMATICA DEL RESORTE DE COMPRESION. EL PETROLEO CONFINADO EN LA SEGUNDA CAMARA MANTIENE EL RESORTE DECOMPRESION CARGADO MIENTRAS EL INYECTOR DE COMBUSTIBLE SE ENCUENTRA EN POSICION CERRADA.
