Abstract (en)
[origin: WO02053905A1] The invention relates to an electrovalve which is used to control an injection valve in a combustion engine. The inventive electrovalve comprises an electromagnet (29), a moveable armature consisting of a plate (28) and a pin (27), in addition to a control valve member (25) which is moved with the armature and cooperates with a valve seat (24) in order to open and close the fuel discharge line (17) of a control pressure chamber (14) of the injection valve (1). The armature plate (28) is mounted in such a way that it can be slidingly displaced on the armature pin (27) as a result of the inert mass thereof in the direction in which the control valve member (25) closes, counter to the tension force of a restoring spring acting upon the armature plate (28). The maximum slide path of the armature plate (28) can be easily adjusted using a final controlling element which is provided on the armature plate. Said controlling element is disposed on a section (42) of said plate (28) opposite the electromagnet (42) and can be moved in relation to the front surface (41) of the armature plate facing the electromagnet in the direction in which the armature plate can slide.
