Abstract (en)
[origin: WO03018990A2] The fuel injection device is provided - for each cylinder of the internal combustion engine with a high-pressure fuel pump (10) with a working pumping chamber (22) and a fuel injection valve (12) connected thereto.The fuel injection valve (12) comprises a first injection valve member (28) which is used to control at least one first injection opening (32) and which on account of the pressure produced in the working pumping chamber (22) can be moved counter to a closing force in a direction of opening (29). A second injection valve member (128) is displaceably guided in the first hollow injection valve member (28) and used to control at least one second injection opening (132); whereby the pressure prevailing in the pressure chamber (40) enables it to be moved counter to a closing force in a direction of opening (29), whereby the second injection valve member (128) is impinged upon, at least indirectly, by the pressure prevailing in a control chamber (50) filled with fuel, said pressure being able to be produced by a feed pump (52) according to operational parameters of the combustion engine in such a way that the second injection valve (128) remains in a closed position or can open.
