Abstract
A fuel injection pumping apparatus includes a displacement piston housed within a cylinder and movable towards one end of the cylinder to effect injection of fuel to an associated engine. The displacement piston is moved by a fluid pressure operable member and valve means is provided to control the application of fluid pressure to the member from a source. There is interposed between the valve means and the cylinder containing the fluid pressure operable member, a variable orifice which acts to limit at least the initial rate of movement of the displacement member thereby to control the initial rate of injection of fuel.
