Abstract: A fuel injector for use in an internal combustion engine includes a valve member that is moveable within a bore of an injection nozzle so as to be engageable with a valve seat region to control fuel delivery through one or more nozzle outlets, an injector body housing an actuator that is operable to move the valve member within the bore, and defining an accumulator volume for storing high pressure fuel. The fuel injector includes a damping chamber in fluid communication with the accumulator volume through a fluid passage, the damping chamber serving to reduce pressure wave activity within the accumulator volume.
