  • Patent number: 4523718
    Abstract: A showerhead of the type including an inlet end, an outlet end, and a bore defining a passage between the two. Diffusing stages are incorporated within the bore. These diffusing stages consist of a plurality of orifices arranged with their centers spaced at regular intervals around a circle of predetermined diameter. A diffusing washer is rigidly mounted to the diffusing stage nearest the outlet end to deflect the water stream from a substantially parallel path to an inclined path which intercepts the interior wall of the outlet end. Aeration holes extending substantially perpendicular to the flow of water allows air to be drawn into the water stream producing turbulence and diffusion of the water stream. In one embodiment the last diffusing stage is movably mounted within said bore in such a manner that if its orifices become clogged it can move axially downstream to allow the water to flow around the stage and exit the showerhead.
