ABSTRACT:
A fuel injector includes a valve member disposed at the upper end of the injector case adjacent a valve recess. The valve member includes a bore and a counterbore, and a tube having a bore is slidably disposed within the counterbore. The valve member bore and the tube bore define a fuel flow passage substantially coincident with the central axis of the injector. The valve member is spring biased to an open position to communicate fuel at transfer pump pressure to the valve recess. At the initiation of the injection cycle, an actuator, preferably an electrical solenoid, closes the valve against the spring force so that fuel is communicated along the central passage to a nozzle.
