ABSTRACT:
Two or more reciprocating pumps are controlled to deliver fluids in adjustable proportions. The pumps are connected to respective actuating levers. Each lever is reciprocated about a pivot, whose position along the lever is adjustable to vary the stroke length of the pump connected to that lever. By so controlling the stroke lengths of the different pumps, the proportions in which they deliver fluids can be adjusted.
