Abstract: A shower head assembly includes a housing enclosing a rotary valve member driven by a water activated motor. A rotatable tubular valve member surrounds the housing and has. an internal cartridge with circumferentially spaced internal passages for selectively directing continuous flow water or cycling flow water directly to nozzle orifices or to radially inner or outer sets of drive jets for a water pulsating turbine wheel. The spray discharge orifices may be adjusted by a control ring which cooperates with the valve member to provide for selecting various spray functions including 1) a normal continuous spray, 2) a fast or slow pulsating spray, 3) a cycling flow rate spray with fast or slow pulsation, 4) a cycling flow rate spray with no pulsation and 5) a discharge spray variable between narrow and wide spray patterns.
