Zusammenfassung:	A liquid fuel injector nozzle has a body terminating at one end in a plurality of substantially tear drop shaped discharge outlets through which fuel may be discharged in a spray and in such manner as to produce spaced apart vena contracta. The nozzle is produced by providing a cylindrical extension at one end of the injector body and forming a plurality of axially extending, circumferentially spaced slots in the extension to produce alternating slots and fingers. The tips of the fingers are deformed into engagement to convert the extension to conical configuration, thereby producing the tear drop shaped openings.
