Abstract
Es wird eine Pumpe, insbesondere eine Kraftstoffhochdruckpumpe, vorgeschlagen, die eine Antriebswelle (12) aufweist, welche mit einem ersten Doppelnocken (18) versehen ist, dessen Nocken um etwa 180° um die Drehachse (13) der Antriebswelle (12) zueinander verdreht angeordnet sind. Es ist ein erstes Paar von Pumpenelementen (22, 23) vorgesehen, die jeweils eine zumindest mittelbar durch den ersten Doppelnocken (18) in einer Hubbewegung angetriebenen Pumpenkolben (28) aufweisen, die um etwa 90° um die Drehachse (13) der Antriebswelle (12) zueinander verdreht angeordnet sind. Die Antriebswelle (12) weist in Richtung ihrer Drehachse (13) neben dem ersten Doppelnocken (18) einen zweiten Doppelnocken (20) auf, dessen Nocken um etwa 180° um die Drehachse (13) der Antriebswelle (12) zueinander verdreht angeordnet sind. Der zweite Doppelnocken (20) ist bezüglich des ersten Doppelnockens (18) um die Drehachse (13) der Antriebswelle (12) um etwa 45° verdreht angeordnet. Es ist ein zweites Paar von Pumpenelementen (24, 25) vorgesehen mit jeweils einem Pumpenkolben (28), der zumindest mittelbar durch den zweiten Doppelnocken (20) in einer Hubbewegung angetrieben wird, und die um etwa 90° um die Drehachse (13) der Antriebswelle (12) zueinander verdreht angeordnet sind.It is a pump, in particular a high-pressure fuel pump, proposed which has a drive shaft (12), which with a first double cam (18) whose cam is about 180 ° about the axis of rotation (13) of the drive shaft (12) are arranged rotated to each other. A first pair of pump elements (22, 23) is provided, each one at least indirectly through the first double cam (18) in a lifting movement driven pump piston (28), about 90 ° about the axis of rotation (13) of the drive shaft (12) are arranged rotated with respect to each other. The drive shaft (12) points in the direction of its axis of rotation (13) next to the first double cam (18) a second double cam (20), the cam by about 180 ° about the axis of rotation (13) of the drive shaft (12) to each other are arranged twisted. The second double cam (20) is relative to of the first double cam (18) about the axis of rotation (13) of the drive shaft (12) arranged rotated by about 45 °. It is a second one A pair of pump elements (24, 25) each provided with a pump piston (28) at least indirectly through the second double cam (20) is driven in a lifting movement, and by about 90 ° the rotation axis (13) of the drive shaft (12) arranged rotated to each other are.
