Abstract
A fuel injection pumping apparatus includes an angularly adjustable cam ring having cam lobes which co-act with rollers to effect inward movement of a pumping plunger. The cam ring is connected to a piston which due to the reaction of the rollers with the cam lobes, develops a pressure acting on a plunger element. The plunger element is spring loaded and when the pressure exceeds a predetermined value the cam ring will be allowed to move angularly to adjust the injection characteristic of the pump.
