Abstract

A fuel pump for use in delivering fuel to a common rail of an internal combustion engine is described. The fuel pump comprises: at least first and second pump units (2,4,6) that are axially spaced along a camshaft (12) to form an in-line pump assembly, wherein each pump unit (2,4,6) includes a pumping plunger (22,24,26), a drive member (48,50,52) that is cooperable with the pumping plunger and driven, in use, by an associated cam arrangement (16,18,20) to impart drive to the plunger upon rotation of the camshaft, and a pump chamber (23,25,27) within which fuel is pressurised for delivery to the common rail. The pump chambers (23,25) of the first and second pump units (2,4) are arranged within a common pump head (34), which is mounted upon a main pump housing (10) having a main housing opening (13) through which the camshaft (12) extends. The pump head (34) defines a high pressure supply passage to which pressurised fuel is delivered from each of the pump chambers and from where pressurised fuel is supplied to the common rail, in use. <IMAGE>
