A fuel injector for fuel-injection systems of internal combustion engines which includes an elongated, axially running, thin-walled, non-magnetic sleeve. At its downstream end, the sleeve has a bottom section, which runs substantially normal to the otherwise axial extent of the sleeve along a longitudinal valve axis. A valve needle, which is securely joined to an armature and a valve-closure member, can move axially within a feed-through opening of the sleeve. The valve-closure member cooperates with a valve-seat surface provided on a valve-seat body, the valve-seat body being pressed into the sleeve and likewise abutting, for example, on the bottom section of the sleeve. The sleeve constituted as a drawn sheet-metal part extends axially over more than half of the axial length of the fuel injector. The fuel injector is suited for applications in fuel-injection systems of mixture-compressing internal combustion engines having externally supplied ignition.
