摘要： The invention relates to a fuel injection device comprising a high-pressure pump (10) which is used to deliver fuel into a tank (12) from which fuel is extracted for injecting into the internal combustion engine. A feed pump (22) is used to deliver fuel from a fuel reservoir (24) to the high-pressure pump (10). Said high-pressure pump (10) comprises a housing (30) provided with an inner chamber (31) in which a drive (32, 34) for at least one pump element (36) pertaining to the high-pressure pump (10) is arranged. Said pump element (36) comprises a pump piston (38) which is driven by a drive (32, 34) in a reciprocating motion and defines a pump working chamber (42) into which fuel is supplied through an admission (60) during a suction stroke of the pump piston (38), and out of which fuel is driven through an outlet (64), into the tank, (12) during a delivery stroke of the pump piston (38). The pump piston (38) moves towards the inner chamber (31) during the suction stroke, and moves away from the inner chamber (31) during the delivery stroke. The feed pump (22) delivers fuel into the inner chamber (31) by means of a connection (23) comprising a check valve (52) which is open towards the inner chamber (31) of the housing (30), and the admission (60) of the pump working chamber (42) is connected to the inner chamber (31).

摘要： The invention relates to a fuel injection device comprising a fuel pump embodied as a double piston pump which is used to pump fuel into the combustion chamber of an internal combustion engine to an injector respectively associated therewith and which is optimized with regard to the injection process thereof. The double piston pump comprises two pistons (70, 73) which pump in parallel along a common line and which are provided with control edges. A control rod (71,74) is associated with each piston (70,73) and is used to control the beginning and end of the pumping. The beginning of the pumping can be adjusted on the first piston (70) and the end of the pumping can be adjusted on the second piston (73). A control pressure is provided prior to the beginning of injection according to engine operation parameters in order to adjust the force acting upon the injector needle (12) in the direction of closure, said pressure enabling pressure to be impinged upon the valve needle (12) in the direction of closure. In order to compensate an alteration in the beginning of injection caused thereby, the control rod (71) of the first piston (70) regulating the beginning of pumping is adjusted accordingly.
