"textContent": "A fuel injector comprising a valve needle (10) which is slidable within a bore (12) and engageable with a seating to control fuel delivery through fast and second outlet openings. The valve needle (10) is moveable between a closed position and first and second fuel injecting positions. The fuel injector further comprises a fuel supply passage (18) for supplying fuel under pressure to the bore (12) and a control chamber (38, 40) which is arranged to receive fuel from the fuel passage (18), in use. The valve needle (10) is acted upon in use by a force due to fuel pressure within the control chamber (38, 40). The supply passage (18) for fuel is provided with a restricted flow passage (18a) which serves to limit the amplitude of pressure waves within the supply passage (18).",
