Bei der erfindungsgemäßen Kraftstoffversorgungsanlage kann eine schaltzeitpunktabhängige Durchflussbegrenzung realisiert werden. Hierzu ist die Absteuereinrichtung mit Hilfe des von der Bypasskraftstoffmenge an derselben angelegten Drucks verlagerbar, um so den Absteuerraum, in welchem zuerst die Absteuerkraftstoffmenge gesammelt wird, nach dem Verlagern der Absteuereinrichtung in den Niederdruckbereich der Kraftstoffversorgungsanlage abzuführen. Dabei ist die Bypasskraftstoffmenge über die Bypassleitung der Absteuereinrichtung verzögert zuführbar, sodass zuerst ein ausreichender Druck zum öffnen des entsprechenden Injektors aufgebaut werden kann. Erst nach dem öffnen des Injektors wird die Absteuereinrichtung verlagert, um den Absteuerraum mit dem Niederdruckbereich der Kraftstoffversorgungsanlage zu verbinden.at the fuel supply system according to the invention can be a switching point-dependent flow limitation will be realized. For this purpose, the Absteuereinrichtung with the help of the pressure applied to it by the bypass fuel amount displaced so as to the Absteuerraum, in which first the Absteuerkraftstoffmenge is collected after moving the Absteuereinrichtung in the Low pressure range of the fuel supply system dissipate. The bypass fuel quantity is via the bypass line the Absteuereinrichtung delayed fed, so first enough pressure to open the corresponding one Injector can be constructed. Only after opening the Injector is the Absteuereinrichtung relocated to the Absteuerraum to connect to the low pressure area of the fuel supply system.
Nach einer vorteilhaften Weiterbildung der Erfindung ist in die Absteuereinrichtung eine Druckhalteeinrichtung integriert, wobei die Druckhalteeinrichtung dann, wenn die Absteuereinrichtung durch den von Bypasskraftstoffmenge erzeugten Druck verlagert worden ist, durch einen von der Absteuerkraftstoffmenge erzeugten Druck entgegen einer von einem Federelement bereitgestellten Federkraft verlagerbar ist, um den Absteuerraum zum Abführen der Absteuerkraftstoffmenge mit dem Niederdruckbereich der Kraftstoffversorgungsanlage zu verbinden.To An advantageous development of the invention is in the Absteuereinrichtung a pressure holding device integrated, wherein the pressure holding device then, when the diversion device by the bypass fuel quantity generated pressure by one of the Absteuerkraftstoffmenge generated pressure against one provided by a spring element Spring force is displaced to the Absteuerraum for discharging the Absteuufraftstoffmenge with the low pressure area of the fuel supply system connect to.
