ABSTRACT:
A faucet spout attachment is disclosed including a flow-limiting plate having flow-controlling orifices. Downstream of the flow-limiting plate, alternate series of perforated disks and wire screens arrest stream velocity and redistribute the velocity profile of the stream to provide laminar flow. A screen in contact with the downstream surface of the flow-limiting plate suppreses noise. The flow-limiting plate includes a central flow-trimming orifice whose diameter is selected so that the overall flow rate of the device falls just within the lower end of a predetermined flow range thereby maintaining stream-generated noise at a minimum.
