Fuel injection valve

A fuel injection valve for intermittently injecting fuel into the combustion chamber of an internal combustion engine, comprising:

• a housing which comprises a high-pressure chamber, which is connected to a high-pressure inlet for fuel, and a low-pressure chamber,
• an injector needle that is longitudinally movable in the high-pressure chamber, interacts with a needle seat, and opens and closes a connection of the high-pressure chamber to an injection opening by the longitudinal movement thereof, the injector needle being urged by a compression spring with a closing force directed towards the needle seat, and the compression spring being supported at one side on a spring sleeve in which the injector needle is guided by a free end of the injector needle,
• a control chamber that is delimited by the spring sleeve and the upper end of the injector needle, and is fillable with pressurized fuel and thus exerts a closing pressure on the injector needle in a controlled manner,
• a control valve that is arranged in the control chamber and divides the control chamber into a first and a second control chamber,
• the control valve consisting of a valve insert guided in a valve guide and a discharge throttle being arranged in the valve guide, which throttle is connected to the first control chamber on one side and to the second control chamber on the other side,
• wherein the connection formed by the discharge throttle between the first control chamber and the second control chamber is temporarily interruptible in a targeted manner.
