Abstract
The present disclosure relates to fuel systems. Some embodiments of the teachings may include a fuel pump comprising: a pump piston having a longitudinal centerline; a camshaft with at least one cam; a roller tappet arranged between the pump piston and the cam; and a tappet body and a roller rotatably held on the roller tappet. The pump piston and the tappet body may be movement-coupled with regard to movements in directions parallel to the piston longitudinal centerline. The roller may be in contact with the cam. The longitudinal centerline may intersect a geometric axis of rotation of the roller. The tappet body defines a tappet body longitudinal centerline parallel to the piston longitudinal centerline. The tappet body longitudinal centerline, in a projected view oriented parallel to the geometric axis of rotation of the roller, runs with a lateral spacing to the piston longitudinal center line.
