Abstract

EL DISPOSITIVO COMPRENDE UNA BOMBA DE PRESION (13) PARA BOMBEAR EL COMBUSTIBLE DESDE UN DEPOSITO (6) HASTA UN CONDUCTO DE PRESION (15) CONECTADO A UN ACUMULADOR (8). ESTE ALIMENTA A UNA SERIE DE INYECTORES (9) PARA UN MOTOR DE COMBUSTION INTERNA. EL DISPOSITIVO INCLUYE ADEMAS UN PAR DE VALVULAS SOLENOIDES (16, 17) DISPUESTAS ENTRE LA BOMBA (13) Y EL ACUMULADOR (8), QUE SON CONTROLADAS POR UNA UNIDAD ELECTRONICA (22) COMO FUNCION DE LOS DATOS DE LA PRESION EN EL ACUMULADOR (8) DETECTADA POR UN SENSOR (24). LA VALVULA SOLENOIDE (16) ESTA NORMALMENTE CERRADA PARA DESCARGAR EL COMBUSTIBLE RECIBIDO DESDE LA BOMBA (13) AL INTERIOR DEL DEPOSITO (6) Y ESTA ABIERTA PARA SUMINISTRAR ESTE COMBUSTIBLE HACIA EL ACUMULADOR (8). EN EL OTRO LADO LA VALVULA SOLENOIDE (17) ESTA NORMALMENTE ABIERTA PARA SUMINISTRAR EL COMBUSTIBLE RECIBIDO AL ACUMULADOR (8) Y ESTA CERRADA PARA DESCARGAR EL COMBUSTIBLE DESDE EL ACUMULADOR AL INTERIOR DEL DEPOSITO (6). ENTRE LAS DOS VALVULAS SOLENOIDES (16 Y 17) SE DISPONE UNA VALVULA DE UN SOLO SENTIDO (18).
