摘要:
An electromagnetically actuatable valve is proposed, which serves in particular to inject fuel into the intake tube of internal combustion engines operating with fuel injection systems. The fuel injection valve includes a valve housing, a core, a magnetic coil and a cylindrical armature which is connected via a rod-like connecting part having a smaller cross section than the armature with a valve closing member embodied in the form of a ball. The valve closing member cooperates with a valve seat provided in a valve seat body. The radial guidance of the armature is effected by a narrow annular disk. The valve closing member is radially guided only by the valve seat in its closed position and by a stop in its open position. Downstream of the valve seat fuel guide bores lead into a preparation bore in the form of a blind bore, which has a diameter of approximately 1 mm.
