Abstract

Un sistema de entrega de combustible para un motor de combustion interna automotor inyectado con fluido tiene una bomba de combustible montada dentro de un tanque de combustible para bombear combustible a traves de una linea de combustible a un motor montado en el riel de combustible que entrega combustible a una pluralidad de inyectores de combustible. Fijada en el lado de salida de la bomba de combustible en la linea de combustible se encuentra una valvula de presion para controlar el flujo de combustible desde la bomba al riel y desde el riel a la bomba. La valvula de presion tiene un alojamiento para contener una valvula de retencion, que se abre al entregar la bomba de combustible una presion predeterminada a la linea de combustible y, una valvula de desahogo, que se abre para permitir el flujo de combustible de la linea de combustible al lado de salida de la bomba de combustible. La valvula de desahogo tiene un punto de ajuste predeterminado mayor que aquel de la valvula de retencion, esta montado en paralelo con la misma de modo que la presion en la linea de combustible se mantenga a un nivel apropiado durante los periodos prolongados de desaceleracion, asi como cuando el motor esta apagado.
