Abstract:
The invention relates to an injection valve which has a piezo actuator that is functionally connected to a nozzle needle by a hydraulic transmission device. The hydraulic transmission device is connected to a pressure reservoir by a sealing gap so that the pressure differences between the pressure reservoir and a hydraulic chamber of the hydraulic transmission device are compensated in the long term.
