发明名称 Fuel injection valve and a method for operating the same
摘要 A fuel injector (1), especially an injector for fuel injection systems of internal combustion engines, includes a first solenoid coil (5), which cooperates with the first armature (9), a valve needle (13) in a force-locking connection with the first armature (9) for actuating a valve-closure member (14), which together with a valve seat surface (15) forms a sealing seat, and a second solenoid coil (6). In this context, the first armature (9) is acted upon in a closing direction by a first resetting spring (11). A second armature (10) cooperates with the second solenoid coil (6) such that, when the first solenoid coil (5) and the second solenoid coil (6) are supplied with current, a limit stop body (18) that is connected with the valve needle (13) strikes against the second armature (10).
