Abstract
A water-saving diffuser for which a user perceives a relatively higher flow rate than the actual flow rate includes a hollow barrel for housing an accelerator disk having a plurality of apertures, a distributor disk having a central aperture of a predetermined size, and a chamber ring interposed between the distributor disk and the accelerator disk to define a chamber region therebetween. The central aperture of the distributor disk can be custom-tailored to produce a specific flow rate for a given water supply pressure. The water-saving diffuser may be used in a water distribution system to provide a predetermined uniform flow rate to all regions of a multi-story building.
