Abstract
A fuel injector includes control valve for controlling fuel pressure in a control chamber. The control valve includes a valve seat; and a valve member having a valve face for cooperating with the valve seat to control fuel pressure in the control chamber. A return line is provided for returning fuel from the control chamber. An armature connected to the valve member and an actuator is provided for actuating the armature. The armature is disposed in an armature chamber. A deflector is provided in the armature chamber to form a first sub-chamber and a second sub-chamber. The first and second sub-chambers are in fluid communication with each other via a first aperture. A pressure differential is established between the first and second sub-chambers when the valve face lifts from the valve seat promoting the flow of fuel from the second sub-chamber into the first sub-chamber through the first aperture.
