    Abstract: A shower head having an upper body adapted for attachment to a water supply pipe, and a lower body swivably supported on the lower end of the upper body, which bodies conjointly define a water passageway therethrough. The lower body has an internal cavity formed therein upstream of the discharge orifice, which internal cavity includes a substantially cylindrical chamber coaxially aligned with and spaced upstream from the discharge orifice. The cavity further includes a frusto-conical chamber which is of a converging funnel-shaped configuration in the downstream direction and extends axially from the cylindrical chamber to the discharge orifice. A bladed member is disposed within the cylindrical chamber for dividing the main water stream into several smaller streams and for causing these streams to be discharged into the frusto-conical chamber at different directions to effect a swirling of the streams.
