It comprises a fuel valve (110), comprising a valve needle (125) and a valve seat (130), for controlling a flow of fuel through the injector (100). It further comprises an electromagnetic actuator (115) with a solenoid (140) and an armature (140) which is operable to lift the valve needle (125) from the valve seat (130) in an opening direction while the solenoid (140) is electrically energized. It also comprises a housing (105) in which the valve needle (125) and the armature (140) are received such that they are displaceable in reciprocating fashion with respect to the housing (105) and with respect to one another. Additionally, it comprises a spring (120) between the armature (140) and the housing (105), for pushing the armature (140) against the valve needle (125) in the opening direction, wherein the spring (120) is configured to provide a hysteretic relationship between force and displacement.",
