A fuel injection pump assembly includes a single fuel metering valve (60) of the sleeve type cooperating through spill ports (74) with the output of a number of coaxially mounted pump plungers (46) and an equal number of fuel delivery valves (82), the plungers being moved axially by an engine driven pump (34) that is drive connected by splines (99) and pin (108) and slot (110) type connections to a centrifugal fuel injection timing advance means (112) and to the metering valve (60) permitting the valve to move angularly and axially relative to the pump to provide changes in timing and rate of injection, and a manually operated lever (180) to axially move the metering valve (60) at will to change the fuel flow rate without influence of fuel pressure forces on the valve end and without the necessity of also moving the mass of the first means (112) that changes the injection timing. |
