Abstract
An improved aspirator device for the accurate blending of an additive liquid such as a liquid concentrate with a pressurized stream of a main liquid such as water. The improvement involves the use of a metering means composed of at least two plastic injection molded restrictors in serial communication. Each restrictor has, as its smallest diameter fluid passage, a hollow bore of from about 0.005 inches to 0.010 inches in diameter and from about 0.005 inches to 0.010 inches in length wherein the dimensions of each hollow bore are such to provide a volume:volume dilution ratio of the additive liquid to the main liquid of from about 1:500 to 1:2,500.
