A shower head includes a housing supporting a low speed rotary valve member driven by a high speed rotary turbine to produce a variable flow rate. The turbine also produces pulsations of water streams discharged from the housing and is shifted axially to produce continuous water streams. A manually actuated control valve and passages with pressure responsive flow control washers provide for selecting different ranges of variable flow or for bypassing the variable flow.

1. A shower head assembly comprising a housing having a passage for directing water into said housing, said housing supporting a flat orifice wall defining a plurality of orifices for directing water from said housing in water streams forming a spray, a rotary turbine supported for rotation on an axis within said housing and driven by water flowing through said housing, said rotary turbine including a radially extending turbine wall positioned adjacent said orifice wall and said orifices and defining an opening for pulsating the water streams discharged from said orifices, and a manually actuated control for shifting said rotary turbine axially relative to said orifice wall while said turbine is rotating to space said turbine wall from said orifice wall and said orifices for producing continuous water streams from said orifices. 2. A shower head assembly as defined in claim 1 and including a first port within said housing and having a first pressure responsive flow control washer for producing a first maximum flow rate into said housing, a second port having a second pressure responsive flow control washer for producing a second maximum flow rate through said housing lower than said first rate, and a manually actuated control valve for directing water selectively through said first port and said second port. 3. A shower head assembly comprising a housing defining a passage for directing water into said housing, a rotary turbine supported for rotation on an axis within said housing and driven by water flowing through said housing, a radially extending flat orifice wall defining a plurality of orifices for directing water from said housing in water streams forming a spray, said rotary turbine including a radially extending flat turbine wall positioned adjacent said orifice wall and said orifices for pulsating the water streams in response to rotation of said turbine, and a manually actuated control for relatively shifting said rotary turbine axially between a first position where said turbine wall produces pulsations of said water streams and a second position with said turbine wall spaced axially from said orifice wall for producing continuous water streams from said orifices while said turbine is rotating. 4. A shower head assembly comprising a housing having a passage for directing water into said housing, said housing supporting an orifice wall defining a plurality of orifices for directing water from said housing in water streams forming a spray, a rotary turbine supported for rotation on an axis within said housing and driven by water flowing through said housing, said rotary turbine including a turbine wall positioned adjacent said orifice wall and said orifices and defining an opening for pulsating the water streams discharged from said orifices, a first port within said housing and having a first pressure responsive flow control washer with a first flow rate for producing a first maximum flow rate into said housing, a second port having a second pressure responsive flow control washer with a second flow rate lower than said flow rate of said first pressure responsive flow control washer for producing a second maximum flow rate through said housing lower than said first rate, and a manually actuated control valve member for directing water selectively through said first port and said second port.
