Abstract (en)
[origin: WO2021197947A1] The invention relates to a nozzle needle for a fuel injector, which nozzle needle comprises an elongated nozzle needle main body which has, at one of its two long ends, a nozzle needle tip for selectively closing an injection opening of the fuel injector. The invention is characterised by a plastic and/or ceramic sleeve for enclosing the nozzle needle main body peripherally along a longitudinal region of the nozzle needle, which longitudinal region is spaced apart from the nozzle needle tip.
