ABSTRACT:
A fuel pumping apparatus for supplying fuel to a supercharged compression ignition engine includes an injection pump having a control member the setting of which is determined by a governor including speed responsive means and a governor spring the force exerted by which is adjustable and opposes the action of the speed responsive means. A stop member is provided to limit the extent of movement of the control rod and the stop is engageable with a cam surface formed on a pivotal lever the setting of which is controlled by an air pressure responsive member subjected to the air pressure existing in the inlet manifold of the engine. In addition the pivot for the lever is mounted on a carrier member which is loaded by a spring. The spring can be deflected under certain operating conditions of the engine, by the force exerted by the governor spring and this provides a measure of torque control.
