Abstract (en)
[origin: WO2018001797A1] The invention relates to a nozzle body (16), in particular in use in a fuel injector (100) for injecting fuel into the combustion chamber of an internal combustion engine. The nozzle body (16) is made in one piece. The nozzle body (16) comprises a pressure chamber (8) which can be supplied, via a supply bore (64), with high-pressure fuel. A nozzle needle (6), which opens or closes at least one injection opening (60), is arranged in the pressure chamber (8) so as to be able to move longitudinally. The at least one injection opening (60) is formed in a nozzle tip (16a) of the nozzle body (16). Cooling channels (30), through which coolant can be made to flow, are formed in the nozzle body (16). The cooling channels (30) include a cooling matrix (35) formed in the nozzle tip (16a).
