An injector is disclosed which comprises a nozzle body arranged to receive fuel under pressure from a pumping chamber. An injection control arrangement in the form of a valve controls injection timing, and a drain control arrangement in the form of a valve controls communication between the pumping chamber and a fuel reservoir. An electromagnetic actuator controls operation of both valves, the actuator including a single, common armature which is associated with both of the valves.
