Abstract
A high pressure fuel supply pump comprising a housing (102) and a pump body (108) fixed within the housing along a body axis and including a plurality of radially oriented plunger bores (20), each bore having a plunger (22) disposed therein. An actuating assembly (116) is disposed around the plunger bores for producing reciprocal motion. A central cavity (120) extends along the axis and intersects the pumping bores to form a pumping chamber (18) in cooperation therewith. An inlet check valve (132) and a discharged check valve (124) are in communication with the pumping chamber.
