    • An electromagnetically actuatable valve is proposed, which serves as a fuel injection valve for fuel injection systems in internal combustion engines. The valve includes a valve housing of ferromagnetic material, at least one magnetic coil mounted on a core of ferromagnetic material, and an armature arranged to actuate a valve closing element which cooperates with a valve seat. The armature protrudes beyond a ferromagnetic annular disk supported on a support shoulder of the valve housing and a stop disk of hard, nonmagnetic material is arranged in the annular groove of the annular disk such that when the armature is resting on the stop disk, a remnant air gap is formed in the axial direction between the annular disk and the armature.
    • 提出一种电磁致动阀,用作内燃机燃油喷射系统的燃油喷射阀。 所述阀包括铁磁材料的阀壳体,安装在铁磁材料芯上的至少一个电磁线圈以及用于致动与阀座配合的阀关闭元件的电枢。 电枢突出超过支撑在阀壳的支撑肩上的铁磁环形盘,并且硬的非磁性材料的止动盘布置在环形盘的环形槽中,使得当电枢搁置在止动盘上时,残余物 在环形盘和衔铁之间沿轴向形成气隙。
