ABSTRACT:
A shower head includes a housing enclosing a first rotary valve member driven by a turbine wheel and gear reducer for cycling the flow rate through the housing between high and low flow rates, and a manually rotatable cross valve shaft provides for selecting the degree of cycling. A second rotary valve member is combined with a second turbine wheel for pulsating the cycling flow rate, and further rotation of the valve shaft provides for hydraulically shifting and stopping the second valve member for bypassing the pulsation to provide a full continuous water flow. Water is discharged from the shower head through flexible tubes arranged in groups which are twisted in response to rotation of a control ring for selecting a spray pattern between a tight penetrating pattern and a wide full pattern.
