Abstract
Die Pumpvorrichtung, insbesondere Kraftstoffhochdruckpumpvorrichtung, weist wenigstens ein Pumpenelement (10) auf, das einen Pumpenkolben (12) aufweist, der über einen Stößel (18) durch eine Antriebswelle (14) in einer Hubbewegung angetrieben wird, wobei die Antriebswelle (14) wenigstens einen Nocken (16) oder Exzenter aufweist, an dem sich der Stößel (18) zumindest mittelbar abstützt. Die Antriebswelle (14) ist über wenigstens eine Lagerstelle (60) drehbar gelagert, wobei der wenigstens einen Lagerstelle (60) Schmiermedium zugeführt wird, das aus der wenigstens einen Lagerstelle (60) zum wenigstens einen Nocken (16) oder Exzenter hin austritt. Die Antriebswelle (14) weist zwischen der wenigstens einen Lagerstelle (60) und dem wenigstens einen Nocken (16) oder Exzenter eine sich im Durchmesser von der wenigstens einen Lagerstelle (60) zum wenigstens einen Nocken (16) oder Exzenter hin vergrößernde Außenkontur (66) auf, die in Richtung der Drehachse (15) der Antriebswelle (14) gesehen im Bereich des Stößels (18) endet. Durch die Außenkontur (66) wird gezielt Schmiermedium zum Stößel (18) geführt. The pump device, in particular high-pressure fuel pump device, has at least one pump element (10) which has a pump piston (12) which is driven in a lifting movement by a drive shaft (14) via a plunger (18), the drive shaft (14) at least one Cam (16) or eccentric on which the plunger (18) is supported at least indirectly. The drive shaft (14) is rotatably mounted via at least one bearing point (60), the at least one bearing point (60) is supplied lubricating medium, which emerges from the at least one bearing point (60) to at least one cam (16) or eccentric out. The drive shaft (14) has, between the at least one bearing point (60) and the at least one cam (16) or eccentric, an outer contour (66) which enlarges in diameter from the at least one bearing point (60) to the at least one cam (16) or eccentric ), which, seen in the direction of the axis of rotation (15) of the drive shaft (14) ends in the region of the plunger (18). The outer contour (66) selectively guides lubricating medium to the plunger (18).

Hierzu sind keine zusätzlichen Bauteile erforderlich. The pumping device according to the invention with the features according to claim 1 has the advantage that directed by the outer contour of the drive shaft from the bearing outlet lubricant is directed to the plunger and thus its lubrication and the lubrication of its support is ensured. For this purpose, no additional components are required.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Pumpvorrichtung angegeben. Die Ausbildung gemäß Anspruch 3 ermöglicht einen gerichteten Abfluss des Schmiermediums von der Antriebswelle zum Stößel hin. Durch die Ausbildung gemäß Anspruch 7 ist auf einfache Weise eine Schmierung der Lagerung der Rolle im Stößel sichergestellt. Die Ausbildung gemäß Anspruch 8 ermöglicht eine gerichtete Einbringung von Schmiermedium zwischen die Rolle und den Stößel. Durch die Ausbildung gemäß Anspruch 9 ist auf einfache Weise eine Schmierung der Lagerung der Rolle sowie des Bolzens im Stößel sichergestellt. Durch die Ausbildung gemäß Anspruch 10 oder 11 wird die Einbringung von Schmiermedium zwischen die Rolle und den Stößel weiter verbessert. In the dependent claims advantageous refinements and developments of the pump device according to the invention are given. The embodiment according to claim 3 allows a directed outflow of the lubricating medium from the drive shaft to the plunger. The embodiment according to claim 7 ensures lubrication of the bearing of the roller in the plunger in a simple manner. The embodiment according to claim 8 allows a directed introduction of lubricating medium between the roller and the plunger. The embodiment according to claim 9 ensures lubrication of the bearing of the roller and of the bolt in the plunger in a simple manner. The embodiment according to
