摘要

The nozzle (1) has a nozzle body (2) provided with an axial guide bore (19) for a nozzle needle (11), where the nozzle needle is guided in the guide bore with an adjustable stroke against an injection-side end. The nozzle needle includes radially directed injection holes (29) in the region of the injection-side end, where the injection holes are closed when the nozzle needle is sealingly enclosed within the guide bore. The injection holes lie in a transition region between a head portion (12) and a shank of the nozzle needle.
