Volumetric proportioning diluter

A volumetric proportioning diluter comprising:

• an elongated housing having first and second ends interconnected by a differential diameter bore passing therethrough, an elongated piston assembly having different diameters that correspond to the diameters of said differential diameter bore is slidably received therein, said piston assembly is movable inside said bore axially,
• a pump actuating means for moving said piston assembly in said first housingend separated from and adjacent pumping means for fluid discharge, said pumping means spaced along said housing length toward said second housing end including at least two completely separate fluid chambers adjacent each other and capable of receiving different fluids of distinctly different displacement volumes due to a difference in said piston diameters inside said differential diameter bore, fluid supply and discharge ports in said separate fluid chambers for fluid communication therewith, including directional control means in said fluid supply and discharge ports and a first directional control in said fluid supply ports of said chambers to allow fluid flow into said fluid chambers and not vice versa and a second directional control in said fluid discharge ports of said chambers to allow fluid discharge from said fluid chambers and not vice versa, individual fluid discharge conduit means connecting said discharge ports to a single conduit for fluid discharge therefrom, said pumping means including a volume displacement piston reciprocating in a chamber pumping concentrate and being carried by said elongated piston assembly for relative axial piston reciprocation therebetween, said displacement piston being slidable therein from a first fluid suction position when said pump actuating means urges said piston assembly to assume a first piston withdrawn position to a second fluid discharge position when said pump actuating means urges said piston assembly to assume a second piston engaged position, thereby providing a simultaneous fluid suction of different volumes into said fluid chambers via said fluid supply ports when said volume displacement piston is moved to said first fluid suction position, and when said volume displacement piston is moved to said second fluid discharge position, resulting in a simultaneous fluid discharge from said fluid chambers via said fluid discharge ports for a dilution thereof in the ratio of respective volumetric proportions of said fluid chambers when delivered via said individual conduits to discharge via said single conduit therefrom, including means for control of volumetric proportions.
