Abstract
A fuel injection pumping apparatus comprises a rotary distributor member having a bore containing a plunger which is moved inwardly to cause delivery of fuel by the apparatus by cam lobes formed on the internal surface of a cam ring. The cam lobes are regularly spaced but in order to balance the forces acting on the distributor member the bore houses a further plunger which is held against outward movement by means of a roller which engages the internal surface of a pair of stop rings mounted in the housing of the apparatus.
