Fluid distribution manifold

TLDR: In this paper, a fluid distribution manifold is described, where the input piping is inserted in through the manifold's circular intake opening and onto its cylindrical input port, and the manifold has the further utility of being expandable to larger sizes.

Abstract: This invention relates to a fluid distribution manifold, where the input piping is inserted in through the manifold's circular intake opening and onto its cylindrical input port. The manifold's intake opening leads through a cylindrical path to a closed terminal end. Along the inner manifold wall, there are arranged in a sequence, which may be in a straight line, a series of straight lines or rows, a spiral, or an alternating 90- or 180-degree arrangement, a number of distribution outlet openings and their respective ports, which may be barbed or ribbed on their outer surface. The manifold has the further utility of being expandable to larger sizes. This is achieved by removing the closed terminal end from one manifold and then inserting and connecting that open terminal end in through another manifold's circular intake opening and into its intake port. To achieve a more uniform fluid flow pressure at each of the distribution outlet ports, two or more manifold devices may be fitted and connected to intake piping which is fitted with a T-joint or Y-joint. In a preferred embodiment, the manifold is composed of acrylonitrile-butadiene-styrene, and is used to distribute air in spas and hydrotherapy baths.
