ABSTRACT:
A liquid fuel injection pumping apparatus for supplying fuel to an internal combustion engine comprises an injection pump to which fuel is supplied by a fuel pump. An air/fuel separator is provided and also a valve including a spring loaded piston for controlling the output pressure of the feed pump, the separator being connected to the outlet of the feed pump and the piston being subject to the output pressure of the pump. A space is defined in the pump housing and from which fuel can be drawn by the feed pump when the output pressure of the feed pump falls due to the entry of air into the feed pump. The air/fuel separator has a restricted outlet through which air and fuel can flow to an outlet in the housing and the space has an outlet which is placed in communication with the feed pump inlet by the piston.
