Abstract
A rotary distributor fuel injection pump includes a pumping plunger housed in a bore and has a spill valve member integrally formed with an actuator piston contained in a cylinder. High pressure fuel from the bore can be admitted to the one end of the cylinder to move the actuator piston and valve member away from the seating by opening an on/off valve. When the spilled fuel has been returned to the bore further fuel flows to the bore by way of the on/off valve and this fuel flows to the on/off valve through a non-return valve from a source of fuel under pressure.
