| 摘要 |
The invention relates to a fuel injection device with a multi-part injector body containing a pressure booster that can be actuated by means of a differential pressure chamber, and includes a pressure booster piston that seals a working chamber off from the differential pressure chamber. An on-off valve, disposed above the injector body can actuate the fuel injection device. A pressure change in the differential pressure chamber occurs via a central control line that extends through the pressure booster piston of the pressure booster.
