Abstract

In known fuel pump assemblies, a single tappet return spring inside the tappet urges a pumping plunger away from a pump head and ensures contact between the tappet and a drive arrangement. The spring rests on a spring seat fixed to the plunger. This design requires the tappet return spring to fit within the tappet, thereby limiting the spring's diameter. The present invention provides a tappet return spring (58) that wraps around the outside of the tappet (40) to urge only the tappet away from the pump head (22a, 22b, 22c). A second plunger return spring (56) working in tandem with the tappet return spring (58) is located within the tappet (40) and urges the plunger (30) away from the pump head (22a, 22b, 22c) and further urges the plunger (30) to maintain contact with the tappet (40).
