Abstract
A proportioning system for creating admixture from diluent and concentrate comprises accumulators which are alternatively repetitively recharged so that one is always on-line. Recharging is controlled by a fluid system including a piston assembly for injecting a measured charge of concentrate into an accumulator being recharged. Diluent is introduced by opening and closing a valve from the diluent supply with the recharging being activated and terminated by level sensing switches associated with the accumulators. Electrical control circuitry and a stroke adjustment mechanism for the piston assembly are also disclosed.
