Shower head with variable flow rate, pulsation and spray pattern
First Claim
1. A shower head assembly comprising a housing, a rotary valve member within said housing, drive means for rotating said valve member in response to the flow of water through said housing, means for directing the water flowing through said housing past said valve member for producing a pulsating flow of water, means including a plurality of orifice tubes for directing the water flowing from said housing in pulsating water streams forming a pulsating spray, and means for manually moving said tubes for infinitely changing the spray pattern between a relatively tight penetrating pattern and a wide full pattern.

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.

- 5. A shower head assembly comprising a housing, means for directing water into said housing, means for directing water from said housing in water streams forming a spray, said means for directing water from said housing including a plurality of flexible orifice tubes, and means for twisting said tubes on an axis for infinitely changing the pattern of the spray between a relatively tight penetrating pattern and a wide full pattern.
- 8. A shower head assembly comprising a housing, a rotary valve member within said housing, drive means for rotating said valve member in response to the 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 water streams forming a spray, and means including a rotary turbine 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 are cycling between said high and low flow rates to produce a pulsating spray that cycles automatically between a slow pulsation rate and a fast pulsation rate.
- 13. A shower head assembly comprising a housing, a rotary valve member within said housing, drive means for rotating said valve member in response to the 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 spaced groups of water streams with each group forming a spray, means within said housing downstream of said rotary valve member for pulsating each group of water streams discharged from said housing while the flow rate of the water streams are cycling between said high and low flow rates, and means for infinitely and simultaneously changing the spray pattern of each group of water streams between a relatively tight penetrating pattern and a wide full pattern.
