Abstract
A fuel injection pumping apparatus includes an injection pump to which fuel is supplied by means of an axially movable shuttle which is contained within a cylinder. Fuel is supplied to one end of the cylinder through a metering valve from a first source of fuel under pressure. The fuel contained in said one end of the cylinder is displaced to the injection pump by applying fuel under pressure to the other end of the cylinder containing the shuttle from a further source of fuel under pressure. The pressure of the further source of fuel is higher than that of the first mentioned source.
