Nozzle

摘要

The nozzle has a stud hole or seat hole (1) arranged on a rear side of a nozzle body (5), and a spray hole (2) that leads outward from the stud hole or seat hole. The spray hole in a region of the spray hole inlet (3) exhibits a non-circular cross section and an oval cross section i.e. elliptical cross section. The spray hole in a region of a spray hole outlet (4) exhibits a circular cross section, and the stud hole or seat hole exhibits a groove (6), where the spray hole leads out from the groove. The spray hole is widened by a counter-bore at the spray hole outlet. An independent claim is also included for a method for manufacturing a nozzle.
