Abstract
A fuel injection system includes first and second pistons slidable within respective cylinders, the second piston being of larger diameter than the first, first valve means through which fuel at high pressure can be admitted to one end of the second cylinder to act on the piston and second valve means through which fuel can be returned from the one end of the first cylinder to the one end of the second cylinder and a third piston which is subjected to fuel at high pressure for returning the first and second pistons towards the one end of the second cylinder when the first valve means is closed and the second valve means is opened. When the first valve means is opened and the second valve means closed, fuel at injection pressure is displaced from the one end of the first cylinder and is supplied to a fuel injection nozzle for supply to an associated engine.
