Fuel injection valve e.g. injector for fuel injection systems of air-compressing, compression-ignition internal combustion engines, has length measuring device, is arranged in valve housing which is provided for measuring lift of actuator

摘要

Fuel injection valve (1) comprises an actuator (16) that is located in a valve housing (2) and a valve closing body (5) that can be actuated by the actuator using a valve needle (6), said closing body co-operating with a valve seat surface (4) to form a seal seat.
