Electromagnetically actuatable valve |
摘要 |
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.
