Abstract
A fuel injection pumping apparatus for supplying fuel to an internal combustion engine is of the rotary distributor type having a distributor member including a transverse bore and a pair of pumping plungers slidable in the bore. At the outer ends of the plungers cam followers are mounted and first and second cam rings are provided having cam lobes to actuate the plungers respectively. The cam follower associated with one plunger has a shoe carrying a follower for engagement with the lobes of the first cam ring only and the cam follower associated with the other plunger has a shoe and a divided roller for engagement with the second cam ring which is also divided. The number of cam lobes on each cam ring is equal to the number of cylinders of the associated engine and the cam rings are positioned angularly relative to each other so that inward movement is imparted to each plunger at the same time during rotation of the distributor member.
