"textContent": "A fuel injection valve (1) for internal combustion engines is presented. The fuel injection valve (1) has a pressure chamber (3) with a fuel injection needle (5) that is longitudinally movable therein. The fuel injection needle (5) cooperates with a valve seat (7) and opens or closes, through its longitudinal movement, the connection of the pressure chamber (3) with an injection opening (9). The fuel injection needle (5) is guided in a control chamber sleeve (15). Furthermore, the fuel injection valve (1) has a control chamber (11) which can be filled with pressurized fuel via an inlet throttle (13) and controls a closing force on the fuel injection needle (5). Additionally, the fuel injection valve (1) has a valve body (17) for receiving a control piston (19). An outlet throttle (21) is provided in the control piston (19), which is connectable on one side to the control chamber (11) and on another side to a low-pressure chamber (23). The control chamber (11) is separated from the pressure chamber (3) by the control chamber sleeve (15) and by the valve body (17). The control chamber sleeve (15) is connected to the valve body (17) in a materially bonded and/or force-locking manner.",
