Abstract

Fuel injection pump in which the piston is driven via a rocker (6) bearing a roller (14) running on a cam (20) and thus providing the rocking motion to drive the piston via the rocker. Here, the roller (14) is borne in a shell-like recess (12) in one of the rocker arms (10) so that the entire outer surface of the roller supports the rocker (6) as it rotates.
