Abstract: A fuel pump housing includes a pumping chamber that is substantially spherical and a drilling intersecting the pumping chamber at an opening. The drilling transitions into the pumping chamber at a transition region of progressively increasing diameter. The transition region and the spherical pumping chamber are configured such that a peak stress in the fuel pump housing is at a location that is spaced away from the opening.

Abstract: A high pressure fuel pump includes a pumping head and a plunger slidably adjusted in a bore. The plunger is provided with a blind bore defining a chamber open in the head end of the plunger and in fluid communication with the compression chamber, the end face of the plunger being limited to a peripheral annular face surrounding the opening, the bore further defining a peripheral cylindrical wall and a bottom face. A filler member is arranged inside the chamber.
