  "textContent": "The invention relates to a nozzle assembly for a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine, comprising a nozzle body (1) and a nozzle needle (2) which is received in a stroke-movable manner to release and close at least one injection opening (3) in a high-pressure bore (4) of the nozzle body (1) and is acted upon in the direction of a sealing seat (5) by the spring force of a nozzle spring (6), which is supported on the one hand directly or indirectly on the nozzle needle (2) and on the other hand on a sleeve (7) surrounding the nozzle needle (2). According to the invention, the sleeve (7) forms a stop surface (A) for limiting the stroke of the nozzle needle (2). Furthermore, according to the invention, a further spring (8) is supported on the sleeve (7), whose spring force is greater than that of the nozzle spring (6), so that the sleeve (7) is axially prestressed via the spring force of the further spring (8) in the direction of a shoulder (9) of the nozzle body (1). Furthermore, the invention relates to a fuel injector with such a nozzle assembly.",
