Abstract
A flow controller, for limiting total maximum water flow through a domestic flow appliance, is provided by a molded flexible body shaped to provide a deformable central flow orifice and an outermost sealing section that is adapted to be operatively positioned at the joint between a supply conduit and the flow appliance, such as a showerhead, aerator, or the like. Associated with the flow controller are: (1) an annular tubular support for positioning the portion of the flexible body with the deformable central flow orifice upstream of the sealing section, and (2) a cavitation noise reducer located immediately downstream of said central flow orifice. The cavitation noise reducer has specific construction features for use with specific appliances, and may also be provided with a downstream tubular flow straightener, or simulator, of selected length and width dimensions to effectively develop a frictional effect that reduces undesirable sound that normally accompanies use of a flow controller.
