Abstract
A pump including a housing defining a plurality of inlet bores. A first interior wall is arranged to at least partially define a first of the plurality of inlet bores. The first interior wall has a contour in a cross section taken normal to the plunger axes. The first interior wall is at least partially defined by the revolution of the contour about a first inlet axis that is normal to and intersects a first of the plurality of plunger axes. The contour includes a cylindrical portion arranged parallel to the first inlet axis, a planar portion extending in a direction perpendicular to the first inlet axis and spaced a first distance from the plunger axis, and a convex bulge portion extending from the cylindrical portion and spaced a second distance from the plunger axis. The contour further includes a V-shaped groove portion extending from the convex bulge portion.
