Abstract
Description
Die Erfindung geht aus von einer Hochdruckpumpe für eine Kraftstoffeinspritzeinrichtung einer Brennkraftmaschine nach der Gattung des Anspruchs 1.The invention is based on one High pressure pump for a fuel injection device of an internal combustion engine the type of claim 1.
Eine solche Hochdruckpumpe ist durch
die
Die erfindungsgemäße Hochdruckpumpe mit den Merkmalen gemäß Anspruch 1 hat demgegenüber den Vorteil, dass die Anzahl der Pumpenelemente und damit die Kraftstoffördermenge und der erzeugte Druck erhöht werden kann, wobei der Bauraum der Hochdruckpumpe nur in axialer Richtung etwas vergrössert wird.The high pressure pump according to the invention with the features according to claim 1 has in contrast the advantage that the number of pump elements and thus the fuel delivery rate and the pressure generated increases can be, the space of the high pressure pump only in the axial Direction slightly enlarged becomes.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Hochdruckpumpe angegeben. Die Ausbildung gemäß den Ansprüchen 2 bis 4 ermöglicht eine gleichmäßige Förderung durch die Hochdruckpumpe und damit eine geringe Belastung der Antriebswelle sowie geringe Druckpulsationen am Auslass der Hochdruckpumpe. Die Ausbildung gemäß Anspruch 5 ermöglicht eine Steigerung der Kraftstoffördermenge, indem die Pumpenelementgruppen parallel zueinander fördern. Die Ausbildung gemäß Anspruch 6 ermöglicht eine Steigerung des erzeugten Drucks, indem die Pumpenelementgruppen in Reihe fördern und jeweils eine Pumpenelementgruppe zur nachfolgenden Pumpenelementgruppe fördert. Die Ausbildung gemäß Anspruch 7 ermöglicht eine Verringerung der Baulänge der Hochdruckpumpe.In the dependent claims are advantageous refinements and developments of the high-pressure pump according to the invention specified. The training according to claims 2 to 4 enables even funding due to the high pressure pump and thus a low load on the drive shaft as well as low pressure pulsations at the outlet of the high pressure pump. The Training according to claim 5 enables an increase in fuel delivery, by pumping the pump element groups parallel to each other. The Training according to claim 6 enables an increase in the pressure generated by the pump element groups promote in series and one pump element group each to the subsequent pump element group promotes. The training according to claim 7 enables a reduction in overall length the high pressure pump.
