ABSTRACT:
A rotary distributor fuel injection pumping apparatus has a rotary distributor member rotatable within a sleeve forming part of the body of the pumping apparatus. The distributor member includes a transverse bore which carries plungers movable inwardly by cam surfaces on a cam ring, as the distributor member rotates. The distributor member is movable axially in the body to vary the amount the plungers can move outwardly and therefore the amount of fuel delivered by the apparatus. The extent of outward movement is determined by complementary inclined surfaces formed on cam followers associated with the plungers and a part rotatable with the distributor member but axially fixed in the body.
