The invention relates to a nozzle assembly for a fuel injector having a nozzle needle (1) which is guided with a reciprocating movement over at least one guide section (5, 6) in a high-pressure bore (2) of a nozzle body (3) for opening and closing at least one injection opening (4) and is loaded at least indirectly by the spring force of a closing spring (8), and having a restrictor-bore body (7) which is loaded by spring force in the axial direction. According to the invention, the restrictor-bore body (7) bears against the nozzle needle (1) and is loaded in the axial direction by the spring force of the closing spring (8). Furthermore, the invention relates to a fuel injector having a nozzle assembly of this type. |
