Abstract
The present disclosure relates to internal combustion engines in general. Some embodiments may include a drive device for a high-pressure fuel pump of an internal combustion engine. It may include an eccentric ring in frictional connection with a drive shaft for converting a rotational movement of the drive shaft about a drive shaft rotational axis into a translational movement; a tappet spaced apart from the eccentric ring for passing on the translational movement from the eccentric ring; and at least two pivoting bodies disposed between the eccentric ring surface and the tappet surface and in contact with the eccentric ring surface and with the tappet surface. The eccentric ring may include at least one flat eccentric ring surface. The tappet may include at least one flat tappet surface. The pivoting bodies may each include a respective extension axis running parallel to the drive shaft rotational axis and pivot about the extension axis.
