Beschreibung
Zusammenfassung:	A fuel injection valve (1), which serves in particular as an injection valve for fuel injection systems of mixture, spark-ignited internal combustion engines, including its actuator (12) and one of the actuator (12) operable valve needle (4). Here, the valve closing body (5) affects the valve needle (4) having a valve seat surface (6) together to form a sealing seat (7). The actuator (12) comprises a coil (13) and on one of the coil (13) actuatable piston body (14). Further, the piston body (14) defines a hydraulic coupler (17). By the actuation of the piston body (14) via the coupler (17) at least indirectly actuating the valve needle (4) is made possible.
