  "textContent": "The invention relates to 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 accommodated with axial stroke movement for releasing and closing 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), further comprising an actuator (7) for controlling the stroke movement of the nozzle needle (2), wherein the actuator (7) is hydraulically coupled to the nozzle needle (2) via a coupling device (8) comprising at least one coupler piston (9, 10). According to the invention, the coupler piston (10) is acted upon directly or indirectly via an axially movable pressure plate (11) by the spring force of a coupler spring (12), which is arranged in the high-pressure bore (4) and axially pretensions the coupler piston (10) in the direction of the actuator (7).",
