Abstract
In a fuel-injection valve, an armature (7) having upper and lower guide surfaces (12, 13) is arranged within a valve housing (1). Via the upper guide surface (12), the armature (7) is guided in a guide borehole (15) of the valve housing (1) directly below the magnet winding (3) of the fuel-injection valve. In this way the losses of magnetic flux are very small.
