Abstract
A fuel injection pump for supplying fuel to an internal combustion engine includes a bore containing a cam actuated pumping plunger. The bore is connected to an outlet during inward movement of the plunger and a spill valve including a spill valve member is operable to spill fuel from the bore to prevent delivery of fuel to the associated engine. The spill valve member includes a piston portion slidable in a cylinder to which fuel under pressure from the bore can be admitted to move the spill valve member to the open position against the action of a spring. The admission of fuel under pressure to the cylinder can be effected by an electromagnetically operable valve or by the use of a control sleeve, recesses on the internal surface of which in conjunction with porting in a rotary part of the pump, form a control valve.
