  "textContent": "Fuel injection nozzle (1) comprises an axially guided piston (16) with a first protrusion (21) entraining an outer nozzle needle (4) in the opening direction and a second protrusion (22) entraining an inner nozzle needle (5), an adjusting drive (18) for displacing the piston, a first control chamber (25) filled with fuel and a second control chamber (27) filled with fuel connected to the first control chamber via a throttle (26). The inner and outer nozzle needles can be displaced relative to the piston in the opening direction against the action of a closing spring (8, 12). Preferred Features: The outer needle nozzle is guided on a chamber wall of the piston chamber on the outer side. The inner needle nozzle is guided on a chamber wall of the piston chamber on the inner side.",
