Zusammenfassung:	An actuator (10) for a fuel injector having a dual coil solenoid. The solenoid coils (14, 16) are connected in parallel and have windings that are wound in opposite directions. The actuator (10) of the present invention defines three air gap surfaces (22, 24, 26), one of which (24) is located in the space shared between the two coils (14, 16). The shared air gap surface (24) has a high flux density due to the additive nature of the magnetic forces between the oppositely wound coils (4, 16). The dual-coil solenoid of the actuator (10) of the present invention creates a very high force and a low inductive load which results in fast injector response times.
