发明名称 Fuel injection valve
摘要 A fuel injection valve for a fuel injection system of an internal combustion engine, in particular for injecting fuel directly into the combustion chamber of the internal combustion engine. The fuel injection valve has a magnet coil, an armature that can be pulled by the magnet coil in a direction of lift against a first return spring, and a valve needle. The valve needle has a first stop surface for the armature, which can be moved relative to the valve needle. The armature is acted upon by a second return spring. In addition, a stationary second stop surface for the armature is provided. The second return spring acts upon the armature in a direction opposite to the lift and in an inoperative position, when the magnet coil is not energized, and holds the armature in contact with the second stop surface so that a distance between the armature and the first stop surface provided on the valve needle is predefined.
