System for increasing flow uniformity

Abstract From the Canadian patent

A pumping mechanism (42) moving in movement increments (80) is controlled to space those movement increments in direct proportion to the volume (76) resulting from each movement increment. In a further aspect movement , increments are grouped to result in approximately equal volumes per group. The mechanism moves continuously through the movement increments in each group. Groups are spaced to result in approximately equal flow volumes per group. The number of groups decreases as the flow rate increases. The number of movement increments in each group and the volume of each group increase as the flow rate increases.
