ABSTRACT:
An apparatus of the prime mover type for reconstituting a liquid concentrate. Water under pressure, supplied by a municipal system, alternately flows into and out of opposite ends of a first cylinder in which a double-acting piston is slideably mounted, thereby reciprocating the same. From the first cylinder, the water flows to a collection hopper where it is mixed with a concentrate requiring reconstitution.
The concentrate is pumped to the collection hopper by a single-acting piston means, disposed in a second cylinder, that is mechanically connected to the double-acting piston. The displacement volumes of the first and second cylinders are the same so that each cycle of the double acting piston pumps two parts of water into the collection hopper for every one part of concentrate pumped thereinto by the single-acting piston.
The mechanical connection between the double and single acting pistons comprises a yoke means that is specifically structured to introduce play into such mechanical connection so that greater ratios of water to concentrate may be pumped into the collection hopper.
