ABSTRACT:
This invention relates to a fuel pump, and more particularly to a fuel pump for delivering high pressure fuel to a fuel injection system of an internal combustion engine. A fuel pump is provided comprising coupling means (30) mechanically coupling a first pump plunger (1) to a second drive means (14) and a second pump plunger (11) to a first drive means (4) whereby, when the first pump plunger (1) is driven by the first drive means (4) from bottom dead center to top dead center, the second pump plunger (11) is driven by the coupling means (30) from top dead center to bottom dead center, and as the second pump plunger (11) is driven from bottom dead center to top dead center by the second drive means (14), the first pump plunger (1) is driven from top dead center to bottom dead enter by the coupling means (30). The use of a mechanical coupling means eliminates the problem of stroke limitation and speed limitation inherent in the use of springs as a means of returning the pump plungers to their bottom dead center positions.
