Abstract (en)
[origin: WO02092998A1] A fuel injection device for internal combustion engines, comprising a fuel injector supplied by a high pressure fuel source and a pressure amplification device together with a pressure amplification device are disclosed. A moving piston in the pressure amplification device separates a chamber connected to the high pressure fuel source from a high pressure chamber connected to the injector, whereby the high pressure chamber (40) is connected to a return chamber (38) by means of a fuel line (46; 75), such that the high pressure chamber may be filled with fuel by means of the return chamber.
