Abstract (en)
[origin: WO2014206609A1] The pumping device, in particular high pressure fuel pumping device, has at least one pump element (10) which has a pump piston (12) which is driven in a reciprocating movement by a drive shaft (14) via a tappet (18), wherein the drive shaft (14) has at least one cam (16) or eccentric, on which the tappet (18) is supported at least indirectly. The drive shaft (14) is mounted rotatably via at least one bearing point (60), wherein the at least one bearing point (60) is fed lubricating medium which exits from the at least one bearing point (60) towards the at least one cam (16) or eccentric. Between the at least one bearing point (60) and the at least one cam (16) or eccentric, the drive shaft (14) has an outer contour (66) which increases in diameter from the at least one bearing point (60) towards the at least one cam (16) or eccentric and ends in the region of the tappet (18) as viewed in the direction of the rotational axis (15) of the drive shaft (14). Lubricating medium is guided in a targeted manner to the tappet (18) by way of the outer contour (66).
