    摘要: A fuel injector, particularly an injector for a fuel injection system of an internal combustion engine, includes a piezoelectric or magnetostrictive actuator and a valve closure member which is actuable by the actuator with the aid of a valve needle and which is cooperable with a valve-seat surface to form a sealing seat. An electromagnetic damping device is provided for damping the movement of the valve needle.
