Abstract
An air eliminator for liquid handling systems comprises a cylindrical container having a liquid inlet and a liquid outlet which are separated from one another by a cylindrical porous barrier positioned to subdivide the interior of the container into first and second chambers. The cylindrical barrier comprises a porous membrane which permits liquid to flow from the first chamber to the second chamber while preventing the passage therethrough of any gases which are entrained in incoming liquid supplied to the first chamber. Any such entrained gases accumulate in an air space located in the first chamber and are vented from the first chamber at atmospheric pressure. Liquid passing through the membrane, free of entrained gases, accumulates in the second chamber within the cylindrical barrier, and then passes to the liquid outlet via a modulating valve in the second chamber. The modulating valve achieves a balance of flow between liquid entering the first chamber and liquid leaving the second chamber, and comprises a float, a valve body, and associated seals so arranged that forces exerted on the seals by the float are at 90.degree. to forces exerted on the seals by liquid seeking to ex…
