Abstract
A fuel injection pump of the rotary distributor type has angularly adjustable stop rings which limit the outward movement of the pumping plungers so as to control the maximum fuel output of the pump. The stop rings have an outwardly extending curved stop surface so that the maximum fuel output can be altered by altering the angular setting of the rings. The latter portion of the stop surface is arranged to curve outwardly at a greater rate so that as the engine speed increases the plungers no longer follow paths determined by said surface so that the maximum fuel delivery of the pump decreases.
