Abstract
Die Hochdruckpumpe weist ein Gehäuse (10) auf, in dem wenigstens ein Pumpenelement (32) angeordnet ist, das einen durch eine im Gehäuse (10) über wenigstens eine Lagerstelle (14, 16) drehbar gelagerte Antriebswelle (12) über ein Übertragungselement (28) in einer Hubbewegung angetriebenen Pumpenkolben (34) aufweist, wobei die Antriebswelle (12) einen Exzenterabschnitt (26) aufweist, auf dem das Übertragungselement (28) über eine Lagerstelle (30) drehbar gelagert ist. Der Lagerstelle (30) des Übertragungselements (28) auf dem Exzenterabschnitt (26) der Antriebswelle (12) wird über ein durch die Antriebswelle (12) verlaufendes Kanalsystem (54, 55, 57) Kraftstoff zur Schmierung zugeführt.The high pressure pump has a housing (10) in which at least one pump element (32) is arranged, which has a drive shaft (12) rotatably mounted in the housing (10) via at least one bearing point (14, 16) via a transmission element (28 ) in a stroke movement driven pump piston (34), the drive shaft (12) having an eccentric section (26) on which the transmission element (28) is rotatably mounted via a bearing point (30). The bearing (30) of the transmission element (28) on the eccentric section (26) of the drive shaft (12) is supplied with fuel for lubrication via a channel system (54, 55, 57) running through the drive shaft (12).
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 Schmierung zumindest der Lagerstelle des Übertragungselements auf dem Exzenterabschnitt der Antriebswelle mit geringem konstruktivem Aufwand verbessert ist, so dass durch die Hochdruckpumpe Kraftstoff unter sehr hohem Druck gefördert werden kann, bei geringem Verschleiß der Lagerstelle.The high pressure pump according to the invention with the features according to claim 1 has in contrast the advantage that the lubrication of at least the bearing point of the transmission element on the eccentric section of the drive shaft with little constructive Effort is improved, so that fuel from the high pressure pump conveyed under very high pressure can be, with little wear on the bearing.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Hochdruckpumpe angegeben. Durch die Ausbildung gemäß Anspruch 3 wird auch die Schmierung der wenigstens einen Lagerstelle der Antriebswelle verbessert. Die Ausbildung gemäß Anspruch 4 und 5 ermöglicht eine weiter verbesserte Schmierung der Lagerstelle durch eine verbesserte Verteilung des Kraftstoffes an der Lagerstelle. Die Ausbildung gemäß Anspruch 6 ermöglicht eine einfache Herstehlung des Kanalsystems in der Antriebswelle. Die Ausbildung gemäß Anspruch 7 und 8 ermöglicht eine Zuführung von Kraftstoff in das Kanalsystem der Antriebswelle auf einfache Weise durch eine Lagerstelle der Antriebswelle.In the dependent claims are advantageous refinements and developments of the high-pressure pump according to the invention specified. Through the training according to claim 3, the Lubrication of the at least one bearing point of the drive shaft is improved. The training according to claim 4 and 5 allows a further improved lubrication of the bearing point through an improved distribution of fuel at the bearing point. The training according to claim 6 enables a simple production of the channel system in the drive shaft. The training according to claim 7 and 8 allows a feeder of fuel in the channel system of the drive shaft to simple Way through a bearing of the drive shaft.
