Abstract
A solenoid valve for controlling a fuel injector of an internal combustion engine having an electromagnet, a movable armature having an armature plate and an armature pin, and a control valve element which is moved with the armature and works together with a valve seat, for opening and closing a fuel drain channel of a control pressure chamber of the fuel injector, is provided. The armature plate is mounted on the armature pin so that it is movable by sliding under the effect of its inertial mass in the closing direction of the control valve element against the tension of a return spring acting on the armature plate. In order to be able to easily set the maximum slide path of the armature plate, an actuator is provided on the armature plate which is arranged on a section of the armature plate facing away from the electromagnet and is adjustable in the sliding direction of the armature plate relative to a face of the armature plate facing the electromagnet.
