Shower head with continuous or cycling flow rate, fast or slow pulsation and variable spray pattern
First Claim
1. A shower head assembly comprising a housing, means for directing water into said housing, a water spray member connected to said housing and having a plurality of orifices for directing water from said housing in water streams forming a spray, a rotary cycling valve member within said housing, a water activated motor for continuously rotating said valve member, a rotatable tubular control valve member surrounding said housing, and said tubular control member including a removable internal cartridge having an inner surface with a series of circumferentially spaced passages for selectively directing water to said spray member or from said cycling valve member to said spray member in response to rotation of said control valve member to provide the option of a cycling flow rate of water to said orifices.

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.

- 1. A shower head assembly comprising a housing, means for directing water into said housing, a water spray member connected to said housing and having a plurality of orifices for directing water from said housing in water streams forming a spray, a rotary cycling valve member within said housing, a water activated motor for continuously rotating said valve member, a rotatable tubular control valve member surrounding said housing, and said tubular control member including a removable internal cartridge having an inner surface with a series of circumferentially spaced passages for selectively directing water to said spray member or from said cycling valve member to said spray member in response to rotation of said control valve member to provide the option of a cycling flow rate of water to said orifices.
- 8. A shower head assembly comprising a housing, means for directing water into said housing, a water spray member connected to said housing and having a plurality of orifices for directing water from said housing in water streams forming a spray, a rotary cycling valve member within said housing, a water activated motor for continuously rotating said valve member, a water actuated rotary turbine wheel within said housing and cooperating with said orifices for pulsating the water streams, radially spaced inner and outer drive ports for directing water streams towards said turbine wheel at radially spaced locations for continuously rotating said turbine wheel selectively at different speeds, and a set of passages for directing water from said valve member alternately to said inner and outer drive ports for automatically and alternately selecting the different speeds of said turbine wheel and for automatically producing corresponding different pulsation frequencies of the water streams.

13. A shower head assembly comprising a housing, means for directing water into said housing, a water spray member connected to said housing and having a plurality of orifices for directing water from said housing in water streams forming a spray, a rotary cycling valve member within said housing, a water activated motor having an output shaft connected to rotate said valve member, said output shaft including an eccentric shaft portion within a rotor chamber, a rotor within said rotor chamber and supported for orbital movement by said eccentric shaft portion in response to pressurized water within said chamber, and a control valve for selectively directing water to said spray member or from said cycling valve member to said spray member in response to movement of said control valve to provide the option of a cycling flow rate of water to said orifices.
