The invention relates to a fuel injection valve comprising an armature (27) and a core (2), which interacts with a solenoid (11), and comprising a valve needle (19), which is connected to the armature (27) and on which a valve closing body (21) is provided. Said valve closing body forms a tight seat together with a valve seat body (29). The fuel injection valve also comprises an adjusting bush (48). This adjusting bush is arranged inside a central recess (46) of the fuel injection valve, is provided for pre-tensioning a readjusting spring (25), and has an axial slot (72). The adjusting bush (48) is designed so that it projects, on the supply side, above a step (49) provided in the central recess (46). On the supply side of the step (49), a gap (51) is provided between the adjusting bush (48) and a wall (47) of the central recess (46). The adjusting housing (48) comprises at least one recess (59a) at at least one end (53) that is situated on the supply side. |
