Abstract
A pressure plate provides metering grooves in a face thereof contiguous to the gears of a gear pump. The grooves communicate certain pockets between adjacent gear teeth with other such pockets so as to meter fluid from pockets in which fluid is trapped at relatively high pressures to pockets in which fluid is trapped at relatively low pressures, thereby controlling the pressure distribution.
