Abstract (en)
[origin: US2008283634A1] In a device for the injection of fuel into the combustion chamber of an internal combustion engine, including an injector nozzle ( 5 ) and a nozzle needle ( 7 ) guided in a longitudinally displaceable manner within the injector nozzle ( 5 ), which nozzle needle ( 7 ) is at least partially surrounded by a nozzle prechamber ( 8 ) and, for the control of its opening and closing movements, capable of being pressurized in the axial direction by the pressure prevailing in a control chamber ( 12 ) filled with fuel, a supply line runs into the control chamber ( 12 ) and a discharge line ( 19 ) in which a magnetic control valve ( 16 ) is arranged leads away from the control chamber ( 12 ). The supply line to the control chamber ( 12 ) is guided through at least one bore ( 14 ) of the nozzle needle ( 7 ), which communicates with the nozzle prechamber ( 8 ) via a supply throttle ( 15 ). Between the control chamber ( 12 ) and the nozzle prechamber ( 8 ) is arranged a further supply throttle ( 35 ), whose passage cross-section during the pass of at least a partial stroke of the nozzle needle ( 7 ) is changeable and/or closable as a function of the stroke of the nozzle needle ( 7 ).
