Abstract (en)

[origin: WO2013098163A1] The invention relates to a nozzle needle (1) and an injector (2) comprising such a nozzle needle (1), as well as to a production method for producing said nozzle needle (1). This nozzle needle (1) for an injector (2) for injecting fuel comprises at least one guiding section (11, 13) with a recess (21) and a guiding surface (14, 15, 16) designed to rest against an inner surface (30) of a nozzle body (3) of the injector (2), said recess (21) at least partially delimiting the guiding surface (14, 15, 16) and being designed to allow a flow of fuel along the guiding section (11, 13), and said guiding surface (14, 15, 16) being guided about the longitudinal axis (10) of the nozzle needle (1) in a helical manner.
