ABSTRACT:
A fuel pumping apparatus comprises a rotary distributor member which is located in a housing. The distributor member mounts a pair of plungers which are moved inwardly to effect displacement of fuel from a bore to an outlet formed in the housing. Fuel is supplied to the bore from a cylinder which contains a piston actuated by a stack of piezo-electric crystals. The crystals are energized by a control circuit which is supplied with timing signals, actual engine operating parameters and demanded engine operating parameters.
