Abstract
A fuel injection pumping apparatus includes a pump the amount of fuel supplied by which is controlled by a control member. The apparatus also includes a governor mechanism comprising first and second sleeves movable axially each sleeve being loaded by a respective spring. The sleeves are movable against the action of the springs by means of a governor weight mechanism including weights and lever means is provided to interconnect the sleeves with the control member. The lever means includes a lever which is pivotally mounted and which has one end coupled to the first sleeve, the lever supporting an angularly movable rod which is coupled to the second sleeve. The rod mounts a member in which is defined a slot the slot accommodating a peg secured to the control member whereby relative axial movement of the sleeves will impart angular movement to the rod which in turn will impart a small movement to the control member, substantial movement of the control member occurring during movement of the sleeve against the action of its spring.
