ABSTRACT:
A fuel injection pumping apparatus includes an injection pump to which fuel is supplied by a throttle from a feed pump. The injection pump includes a piston which is movable to adjust the timing of delivery of fuel. The throttle comprises an axially movable member which is spring loaded against the action of the pressure of fuel delivered by the feed pump and formed in the throttle is a blind drilling which communicates with a groove. A port is in constant communication with the groove and is connected to the cylinder containing the piston. A port is in variable communication with the groove and communicates with an inlet through which fuel is supplied to the injection pump. The axial setting of the member determines the amount of fuel supplied to the engine and the drilling is formed as or includes a restrictive orifice. The pressure downstream of this orifice varies in accordance with the outlet pressure of the feed pump and also the quantity of fuel which is being supplied to the engine.
