ABSTRACT:
A fuel injection pump includes a plunger reciprocable by an engine driven cam in a bore from which extends an outlet connected in use to a fuel injection nozzle. A spill valve is utilized to control the fuel flow to the nozzle by diverting fuel from the outlet to a low pressure source. In order to prolong the valve closure period a cylinder is provided in which is located a spring loaded piston. When the valve is closed a predetermined volume of fuel is passed to the cylinder to achieve displacement of the piston after which delivery of fuel takes place through the nozzle. The period of closure of the valve in order to achieve delivery of a specific volume of fuel through the nozzle is therefore extended.
