A fuel injection pumping apparatus includes an axially movable distributor member which carries pumping plungers movable inwardly to effect delivery of fuel by means of cam lobes formed on a cam ring. The axial position of the distributor member determines the amount of fuel supplied by the apparatus each time the plungers are moved inwardly. The distributor member is moved axially by varying the volume of liquid in a chamber, the distributor member moving as the volume of liquid increases against the action of a spring. The volume of liquid is controlled by means of a sleeve axially movable by means of a governor mechanism which includes weights. The sleeve controls the size of a port which communicates with the chamber and liquid is supplied to the chamber through a passage from a supply pump.
