Abstract
An electromagnetically actuated fuel injector supplies fuel to an internal combustion engine. The injector has a body with an inlet and a nozzle. A needle valve is selectively moveable within the body in response to actuation of the fuel injector. A reduced center-body coil spring is disposed within the fuel injector and biases the needle valve in a closed position. The reduced center-body coil spring has a substantially hour glass shape to prevent rubbing with the components of the fuel injector.
