Abstract

A fuel injection pump in which the onset of fuel injection can be varied by way of a device operating in dependence on speed in a conventional manner by turning the roller ring which cooperates with a cam plate which in turn is connected with the pump and distributor piston. In accordance with the present invention the angle of twist of the roller ring is limited by a stop which engages this ring.
