    摘要: A fuel injection valve includes a valve needle passing through the valve opening to the valve closing body arranged on the spray outlet end. A closing spring prestresses the valve needle in a direction opposite its opening direction aimed in the direction of spraying, so that the valve closing body is in contact with the valve seat on the spray outlet end when the fuel injection valve is closed. The armature is kept engaged and in contact with the valve needle by means of a bearing spring which acts in the direction of opening by means of a connecting piece arranged between the armature and the valve needle. The connecting piece includes a suitable insulation element for providing insulation against high voltage.
