A pump including a hydraulically balanced distributor head (76) housing a pair of opposed plungers (74) actuated by an annular cam (82) and rotatably driven by a shaft (16) in synchronisation with the operation of an engine. The face type distributor head (76) has an outlet part (108) formed in an insert (102) sequentially interconnecting the pumping chamber (84) of the injection pump (14) to a plurality of injection parts (26,30 etc.) symmetrically disposed along the circumference of a circle concentric with the shaft (16) on the internal face of a distributor block (24) enclosing one end of a housing (10). |
