Shower spray apparatus
First Claim
1. Showerhead spray apparatus, comprising:
- a hollow housing with an inlet for pressurized water and a wall having first and second spray exit openings therein;
a pulsating spray generator located within said housing and having an outlet end slidably received within said first housing spray exit opening; and
slide valve means interconnected with said pulsating spray generator and having parts movable therewith for selectively communicating pressurized water from the inlet with the housing interior, the pulsating spray generator or proportionately therebetween.

Abstract
The shower spray apparatus has a hollow housing with three spray exit openings in a common face, two for normal spray and the third for pulsating spray. Incoming pressurized water is fed into a diverter which includes a slide valve adjustable to proportion the flow of water along either of two paths exclusively, or in a continuous variable range between the two paths. The first path of fluid flow from the slide valve terminates in the two normal spray exit openings, while water flowing along the second flow path drives a turbine and exits via openings in the pulsating outlet. The rotating turbine includes a mask which sequentially covers and uncovers the spray outlet to provide the pulsating output. A knob on the spray apparatus housing is adjustably rotatable to operate a slide valve throughout a full range of adjustment, providing either all normal spray, all pulsating spray or any ratio therebetween. Adjustment of the slide valve adjusts the normal spray outlet to compensate for the change in water supply thereto and thereby provide a substantially uniform spray pattern and spray particle size.

8. Spray apparatus, comprising:
-
a hollow housing with an inlet for connection to a source of pressurized water and a wall having first and second spray exit openings therein; a pulsating spray generator located within said housing and having an outlet end slidably received within said first housing spray exit opening for providing a pulsating spray outwardly thereof, said pulsating spray generator including a generally cylindrical housing having an end wall with a plurality of openings therein, and a rotor rotated by pressurized water from the valve means which interrupts water flow through each of the openings in the end wall at least once each rotation to provide a pulsating spray; an adjustable nozzle in said housing second spray exit opening for providing normal spray outwardly thereof; and valve means interconnected with said pulsating spray generator and said nozzle and adjustably movable therewith for selectively communicating pressurized water from the inlet to the housing interior and said nozzle, the pulsating spray generator, or in continuously proportional amounts between said nozzle and the pulsating spray generator. - View Dependent Claims (9)
