ABSTRACT:
A fuel injector (1) is provided with a magnetic coil (10), which cooperates with an armature (20) acted upon by a restoring spring (23), the armature forming an axially movable valve part together with a valve needle (3). A valve-closure member (4), which forms a sealing seat with a valve-seat member (5), is provided at the valve needle (3). A flange (14), which penetrates the armature (20) through an opening (19) of the armature (20) and which is connected to the valve needle (3) by force-locking, has at least one radial fuel channel (11) with whose aid an inner chamber (29) of the fuel injector (1) is able to be connected to a recess (22) of the valve needle (3) upon actuation of the fuel injector (1).
