Abstract
A fuel injection pumping apparatus of the rotary distributor type includes a rotary distributor member which is biased axially in one direction by a spring and is movable in the opposite direction by fluid pressure in a chamber. The axial setting of the distributor member determines the amount of fuel delivered by the apparatus. Fuel is supplied to the chamber through a supply path including a port and a groove which register intermittently as the distributor member rotates. Fuel is allowed to drain from the chamber through a drain path which includes a further port and a tapered groove defined by the distributor member and an axially adjustable sleeve surrounding the distributor member. The further port and the tapered groove register intermittently and it is arranged that the supply path and the drain path are closed to create a hydraulic lock in the chamber during the time mechanical forces are applied to the distributor member.
