ABSTRACT:
A vane-type pump which including a housing having interior surfaces defining a pumping chamber having a diameccentric configuration. A diameccentric configuration is defined for purposes of this invention as a substantially circular shaped body whose constant diameter rotates about a point which is offset with respect to the centroid of that shaped body. The diameccentrically configured pumping chamber includes a perimeter section, a front wall, a rear wall, an intake port, a discharge port, an intake region, and a discharge region. A pump rotor is disposed within and is diameccentric to the pumping chamber for rotation within the pumping chamber for pressurizing and pumping a fluid. The pumping chamber, which typically has a generally elliptical shape, has a substantially uniform diameter when measured through the longitudinal center of the rotor. The perimeter of the pumping chamber in the discharge region has a shape such that fluid is discharged through the discharge port in a substantially uniform, non-pulsating flow. The outer edge of the outlet port is aligned with the perimeter of the pump housing to permit the unimpeded flow of entrained particulates out of the housing.
