Electromagnetic valve for controlling a fuel injection of an internal combustion engine

The present invention relates to a solenoid valve for controlling a fuel injector of an internal combustion engine, including an electromagnet (29), a movable armature featuring an armature plate (28) and an armature pin (27), as well as a control valve member (25) which is moved with the armature and cooperates with a valve seat (24), for opening and closing a fuel discharge passage (17) of a control pressure chamber (14) of the fuel injector (1), the armature plate (28) being supported on the armature pin (27) in such a manner that it is slidably movable in the closing direction of the control valve member (25) under the action of its inertial mass, against the elastic force of a return spring (35) that acts upon the armature plate (28); and including a hydraulic damping device which permits damping of a post-oscillation of the armature plate (28) during its dynamic sliding on the armature pin (27). To facilitate the assembly and reduce a disadvantageous post-oscillation process of the armature plate, it is proposed for the return spring (35) to be braced, with its end (62) facing away from the armature plate (28), against a supporting piece (50) which is mounted on and moved with the armature pin (27) and which, at the same time, constitutes a part (57) of the damping device.
