Abstract
The invention relates to a fuel injection nozzle for use in an internal combustion engine, having a nozzle body (), in which is formed a pressure chamber () fillable with fuel under high pressure and in which a longitudinally displaceable nozzle needle () is arranged, wherein the nozzle needle () has a sealing face () with which it interacts with a conical body seat () formed in the nozzle body () and thereby opens and closes the connection from the pressure chamber () to a blind hole (). The blind hole () forms a cylindrical section () directly adjoining the body seat () so that an inlet edge () is formed at the transition between the body seat () and the blind hole (). In the nozzle body () is formed at least one injection opening () which opens into the blind hole (). The cylindrical section of the blind hole () has a reduced diameter so that a shoulder () is formed in the blind hole (), wherein the at least one injection opening () opens into the blind hole () between the shoulder () and the inlet edge ().
