Abstract
A fuel injector for the injection of fuel into the combustion chamber of an internal combustion engine includes a valve needle guided in a nozzle body, the valve needle being actuable by an actuator and acted upon by a restoring spring in such a manner that a valve-closure member which is in operative connection to the valve needle is retained in sealing contact against a valve-seat surface. Formed at a downstream-side end of the fuel injector is a projection which projects beyond the valve-closure member of the fuel injector.
