An injection valve for injecting fuel into an internal combustion engine may include an actuator and an injection needle associated with a sealing seat. A hydraulic transmission unit may establish an effective connection between the actuator and the injection needle. The transmission unit may include two movable pistons, between which a movable pot is arranged. The movable pot may be guided within another stationary pot. The first piston may be guided through the bottom of the other pot, and the second piston is guided within a sleeve section of the pot. A first chamber may be formed between the other pot and pot, and a second chamber may be formed between pot and the second piston. The two chambers may be interconnected via at least one duct. One piston may be effectively connected to the injection needle, while the other piston may be effectively connected to the actuator. |
