Abstract: A fuel injection apparatus for delivering a metered quantity of fuel to an engine comprising a valve controlled port through which the metered quantity of fuel is delivered to the engine the valve being resiliently urged to a position to close said port. Electromagnetic means operable when energized to displace said valve member from the closed position to permit delivery of the metered quantity of fuel through the port to the engine. The electromagnetic means including an armature member movable in a first direction in response to energizing of the electromagnetic means to effect the opening of the port. The armature having a limited free movement in the first and the opposite directions independent of the valve member when the electromagnetic means is not energized and the valve member is in the port closed position.
