Abstract (en)

The invention relates to a fuel valve actuator for an engine. The actuator has an armature (26) movable to open and close the valve, a permanent magnet (28) which urges the armature (26) toward the closed position, biasing means which urges the armature (24) toward the open position, and an electromagnet (24) which produces a magnetic field that interferes with the magnetic field of the permanent magnet (28) in order to produce a resultant magnetic field which at least reduces the force provided by the permanent magnet on the armature (26). This provides a fast fuel valve actuator with a fast response time. A method of actuating a fuel valve is also provided.
