Abstract
An actuator arrangement for use in a fuel injector of an internal combustion engine includes an inner core (30) comprising a plurality of laminates (30a) and a first outer pole (32) for receiving at least a part of the inner core (30), wherein the inner core (30) and the outer pole (32) together define a first volume (46) for receiving a first electromagnetic winding. An injector is provided in which the actuator arrangement controls a valve arrangement, either a spill valve or a nozzle control valve, or both, so as to control injection by the injector.
