Abstract

The present disclosure relates to a nozzle body for a fuel injection valve, the nozzle body including a cavity and an injection channel for dispensing fuel from the cavity. The injection channel includes a first section and a second section downstream of the first section, the first and second sections having a common interface. The first section extends from a fuel inlet opening to a second opening disposed at the common interface. The cross-sectional area of the first section monotonically decreases from the fuel inlet opening to the common interface. The cross-sectional area of the second section monotonically increases from the common interface to the fuel outlet opening.
