Abstract
A solenoid-operated fuel injection valve includes a container into which fuel is introduced, a needle member that is disposed in the container and that moves longitudinally, and an electromagnetic controller provided with first and second magnetic circuits through which suction forces can be controlled independently of each other. The electromagnetic controller changes an area of a fuel flow passage defined as a space between an inner surface of the container and an outer surface of the needle member by moving the needle member by means of the suction forces. The fuel injection valve may provide two limit strokes to achieve variable injection rates.
