| 摘要 |
A nozzle body (20) for a nozzle assembly (2) of a fuel injector (1), particularly of a common-rail-fuel injector (1), has a needle bore (26, 22) for a needle piston (36) of a nozzle needle (30), wherein the needle bore (26) ends in a blind hole (266) above a nozzle needle seat (262) for a sealing surface (362) of a nozzle needle tip (360) of the nozzle needle (30), into the blind hole a tappet (366) of the nozzle needle tip (360) can be inserted, wherein a recess (264) is provided in a transitional region (202) from the nozzle needle seat (262) to the blind hole (266). A method introduces a nozzle bore (22) into a nozzle body (20) of a fuel injector (1), particularly of a common-rail-fuel injector (1).
