ABSTRACT:
A fuel injection valve includes a casing, a coupling for connection to a fuel supply line, a valve seat carrier arranged downstream from the coupling, and a valve seat body mounted on the valve seat carrier and having a valve seat face. The fuel injection valve also includes a valve closing body which can move between a closed position in contact with the valve seat face and an open position elevated from the valve seat face. The coupling includes a first sheet metal part, and the valve seat carrier includes a second sheet metal part. The sheet metal parts are shaped by a deformation stress exceeding the yield point of their material and they are joined together to form the casing.
