Shower head with variable flow rate, pulsation and spray pattern
First Claim
1. A shower head assembly comprising a housing, means including a plurality of orifices for directing water flowing from said housing in water streams forming spray, means including a rotary turbine wheel cooperating with said orifices for pulsating the water streams, and control means for hydraulically shifting said turbine wheel axially to a non-pulsating position.

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.

6. A shower head assembly comprising a housing, means for directing water into said housing, flexible body means defining a plurality of orifices for directing water from said housing in water streams forming a spray, and a control member connected to twist said flexible body means on an axis for infinitely changing the pattern of the spray between a relatively tight penetrating pattern and a wide full pattern.
- 7. A shower head assembly comprising a housing, a rotary valve member within said housing speed reducing, drive means for rotating said valve member in response to a flow of water through said housing, means for directing the water flowing through said housing through said valve member and for automatically and continuously varying the flow rate between high and low flow rates to produce a cycling flow rate, means for directing the water from said housing in a plurality of water streams forming a spray, means including a water activated rotary turbine wheel within said housing downstream of said rotary valve member for pulsating the water streams discharged from said housing while the flow rate of the water streams is cycling between said high and low flow rates, and means for moving said turbine wheel axially to a non-pulsating position for producing continuous water streams which cycle between said high and low flow rates.
- 10. A shower head assembly comprising a housing, a rotary valve member within said housing, a water activated rotary turbine wheel supported within said housing, a speed reducing drive connecting said turbine wheel to said valve member for rotating said valve member at a substantially slower speed than the speed of said turbine in response to the flow of water through said housing, a passage for directing the water flowing through said housing through said valve member while said valve member is rotating at said substantially slower speed for automatically and continuously varying the flow rate between high and low flow rates to produce a cycling flow rate, and body means defining a plurality of orifices for discharging water flowing through said housing in water streams forming a spray pattern.
