Fuel injection valve comprising an adjusting bush

Abstract

A fuel injector includes an armature (27) and a core (2), which interact with a solenoid coil (11); a valve needle (19), which is connected to the armature (27), and on which a valve-closure member (21) that forms a sealing seat together with a valve-seat member (29) is provided; and an adjustment sleeve (48) for prestressing a restoring spring (25), the adjustment sleeve being situated in a central opening (46) of the fuel injector and having an axial slot (72). The adjustment sleeve (48) is such that, on the inflow side, it overlaps a step (49) formed in the central opening (46). On the inflow side of the step (49), a gap (51) is formed between the adjustment sleeve (48) and a wall (47) of the central opening (46). The adjustment sleeve (48) has at least one cutout (59a) at an inflow-side end (53).
