Abstract (en)
[origin: WO0250424A2] The invention relates to an electromagnetic valve for controlling an injection valve of an internal combustion engine. The electromagnetic valve comprises an electromagnet (29), a displaceable armature with an armature plate (28) and with an armature pin (27), and a control valve element (25). Said control valve element is displaced with the armature, interacts with a valve seat (24), and is provided for opening and closing a fuel discharge channel (17) of a control pressure space (14) of the injection valve (1). The armature plate (28) is displaceably mounted on the armature pin (27) in a manner that permits it slide, under the influence of its inert mass, in the closing direction of the control valve element (25) counter to the tension force of a return spring (35) acting upon the armature plate (28). When in a position of rest, the armature plate is pressed by the return spring (35) against a stop part (26) arranged on the armature pin (27). The stop part (26) is designed in such a manner that it peripherally encircles the armature pin by more than 180 DEG in a plane perpendicular to the direction of motion of the armature pin (27).
