Abstract (en)
[origin: DE19860678A1] Disclosed is a fuel injection device for internal combustion engines. Said device supplies fuel from a high pressure fuel source (1) to fuel injection valves (9) controlled by a control device (10). The fuel injection device has an injection valve member (12) that is impinged upon by the supplied high pressure fuel via an exposed annular area (14) and that can be opened for effecting injection. The fuel is supplied by means of a pressure line (10a, 10b). The passage of fuel is controlled by a control valve (20) whose control valve is movable in a valve chamber (24) between two valve seats (30, 31) and which controls the connection between the high pressure fuel source (1) and the fuel injection valve (9) for effecting a preinjection and a main injection.
