Abstract (en)
[origin: WO2004036027A1] The invention relates to a fuel injection device (1) comprising a multi-piece injector member (4; 8, 9, 10) which accommodates a pressure booster (11). Said pressure booster (11) can be actuated via a differential pressure chamber (17) and is provided with a pressure-boosting piston (14) which separates a working chamber (12) from the differential pressure chamber (17). The inventive fuel injection device (1) also comprises an on-off valve (5, 70) which is disposed above the injector member (4; 8, 9 10) and via which the fuel injection device (1) can be actuated. The pressure within the differential pressure chamber (17) of the pressure booster is modified via a central control line (31) which extends through the pressure-boosting piston (14) of the pressure booster.
