Abstract
Official abstract text for this publication.
An injection valve for injecting fuel into an internal combustion engine may include an actuator, an injection needle associated with a sealing seat, and a transmission unit that establishes an effective connection between the actuator and the injection needle. The transmission unit may include a pressure chamber including two movable pistons that are guided within a movable pot. The first piston may be guided through a bottom of the pot while maintaining a first sealing gap, and the second piston may be guided within a sleeve section of the pot while maintaining a second sealing gap. One piston may be effectively connected to the injection needle, while the other piston may be effectively connected to the actuator.
