Abstract
The method involves subjecting of the load on the armature pin in the closing position of the closing element (16), whereby the armature pin (21) causes the push, thereby changing the armature stroke. The fuel injector (1) comprises a solenoid valve with an integrated fuel recirculation (11) and an injector body with a valve piece (4).
