ABSTRACT:
A fuel pumping apparatus for supplying fuel to an internal combustion engine includes a positively reciprocated plunger which during movement in a fuel delivery direction displaces fuel from a first chamber and draws fuel into a second chamber and vice versa. The fuel displaced from the first chamber is used to displace a shuttle towards one end of a cylinder from which extends an outlet. Fuel displaced from the second chamber is used initially to displace the shuttle away from the one end of a cylinder until a control valve is closed and is then supplied to an accumulator which before the control valve is closed supplies fuel to the first chamber.
