ABSTRACT:
A fuel injection device includes an injection valve connected in an injection line for the fuel and having a nozzle chamber and a control chamber that are both connected to the injection line, an on-off valve for switching back and forth between a lower injection pressure and a higher injection pressure, and a valve device for controlling the pressure prevailing in the control chamber. A shared actuator is provided for the valve device and the on-off valve, wherein the actuation distance of the shared actuator required to open the on-off valve is greater than the actuation distance required to open the valve device.
