ABSTRACT:
A proportioner apparatus is capable of proportioning and admixing at least two liquids at relatively low pressures and minimizing waste of the liquids. The proportioner apparatus has a pressurizable reservoir for each liquid and a mix reservoir. The liquid reservoirs define an interior having a lower region. A fluid communication conduit provides fluid communication between the interior of the mix reservoir and the interior of the liquid reservoirs. A run-out conduit provides fluid communication between the lower region of at least one of the liquid reservoirs and the mix reservoir interior. When it is desired to run-out the liquid in the one liquid reservoir fluid flow from the one liquid reservoir through the fluid communication conduit is suspended and fluid flow through the run-out conduit is permitted.
