Abstract
Disclosed herein is a fuel pump comprising a housing including therein a high pressure fuel chamber, a fuel outlet valve communicating with the high pressure fuel chamber and being operable to prevent fuel inflow and to permit fuel outflow when the fuel pressure is above a predetermined level, a fuel inlet valve communicating with the high pressure chamber and being operable to prevent fuel outflow and to permit fuel inflow, and a bearing bore extending from the high pressure chamber, a rod slideably and sealingly supported in the bearing bore for movement relative to a retracted position, and structure located in the housing for displacing the rod from the retracted position and in the direction toward the high pressure fuel chamber through an initial stroke length without encountering substantial resistance and thereafter displacing the rod through a subsequent stroke length which is effective to highly pressurize the fuel in the high pressure fuel chamber.
