Abstract
A fuel injection pumping apparatus comprises an injection pump which is driven in timed relationship with the associated engine, and a feed pump which supplies fuel under pressure to the injection pump. A throttle member controls the quantity of fuel which is supplied to the injection pump and a fluid pressure operable piston which is movable against the action of a spring to advance the timing of injection of fuel to the engine, the piston being subjected to the outlet pressure of the feed pump. A fluid pressure operable stop member is provided which when the apparatus is at rest, positions the piston to provide the correct timing of injection of fuel for starting purposes.
