Abstract
A fuel pumping apparatus for supplying fuel to an internal combustion engine includes a throttle member having a groove which can register with a port to control the fuel flow to an injection pump forming part of the apparatus. The throttle member is angularly movable by a governor and is also axially movable. The groove has an inclined edge so that the variation in the axial setting will also control the fuel flow. A pivotal lever has one end engaging the throttle member and its other end mounts a cam follower which engages with a cam surface formed on a cam ring which is part of the injection pump and which is angularly movable in accordance with the speed of the engine. As the speed varies so also does the axial setting of the throttle member.
