Abstract:
A fuel injection device for an internal combustion engine, comprisingat least one high pressure reservoir (12) a high-pressure pump (10) that supplies highly pressurized fuel to the at least one high-pressure reservoir (12), a plurality of injectors (20) disposed in cylinders of the engine and connected to the high pressure reservoir, a common low-pressure reservoir (50) connected to said injectors (20), a pressure holding valve (52) maintaining a predetermined low pressure in the low-pressure reservoir (50), a pressure regulating valve (60) which can regulate the pressure in the high-pressure reservoir (12) by diverting fuel from the at least one high-pressure reservoir (12) through a diversion connection (62) into a low-pressure region, and the diversion connection (62) of the pressure regulating valve (60) connected to the low-pressure reservoir (50).
