Abstract (en)
[origin: DE19921489A1] The invention relates to a fuel injection valve (1), in particular, to an injection valve for fuel injection systems of internal combustion engines. Said fuel injection valve has a piezoelectric or magnetostrictive actuator (21) and a valve closing body (5) which can be operated by the actuator (21), by means of a valve needle (4) and which interacts with a valve seat face (7) to form a tight seat. An electromagnetic damping device (40, 41) is also provided to damp the movement of the valve needle (4).
