GEAR PUMP

摘要

A gear pump having a power rotated pinion and an internal gear effecting positive displacement is provided including a filler or diverter element intermediate the toothed pumping elements for the purpose of directing flow into the recesses between the teeth of the rotative pinion from the suction side of the pump. Such diverter component insures filling of the recesses and avoids turbulence and cavitation thereby substantially decreasing pump noise, particularly at high speeds.
