Abstract

The shower flow controller attaches on the shower arm, and the shower nozzle attaches thereto. The flow controller has a first orifice which is adjustable from within the body of the flow controller for minimal shower flow. The flow controller also has a second orifice which can be manually opened against a spring for bursts of additional water flow for rinse-off or the like. The second orifice is normally larger and is normally closed by spring force.

Claims

1. A shower flow controller comprising:

a valve body, inlet and outlet connections to said valve body for connecting a water supply to said inlet connection and for connecting a showerhead to said outlet connection;

a wall in said valve body separating said inlet connection from said outlet connection, first and second openings through said wall to permit parallel flow of water from said inlet connection to said outlet connection, said second opening being adjustable; and

means for closing said first opening and means for opening said first opening, said means for opening said first opening normally closing said first opening until manually actuated and for reclosing said first opening when manual actuation is terminated so that normal limited flow is only through said second opening until said first opening is manually opened and manually retained open.

2. A shower flow controller comprising:

a valve body, inlet and outlet connections to said valve body for connecting a water supply to said inlet connection and for connecting a showerhead to said outlet connection;

a wall in said valve body separating said inlet connection from said outlet connection, said wall having a first opening therethrough, said wall having an orifice body therein, said orifice body having an orifice therethrough, said first opening and said orifice to permit parallel flow of water from said inlet connection to said outlet connection; and

means for closing said first opening and means for opening said first opening, said means for opening said first opening normally closing said first opening until manually actuated and for reclosing said first opening when manual actuation is terminated so that normal limited flow is only through said orifice until said first opening is manually opened and manually retained open.

3. The shower flow controller of claim 2 wherein there is a holder within said valve body and said orifice body is adjustable with respect to said holder to adjust the flow through said orifice in said orifice body.

4. The shower flow controller of claim 3 wherein said holder is on said means for closing said first opening.

5. A shower flow controller comprising:

a valve body, inlet and outlet connections to said valve body for connecting a water supply to said inlet connection and for connecting a showerhead to said outlet connection;

a wall in said valve body separating said inlet connection from said outlet connection, first and second openings through said wall to permit parallel flow of water from said inlet connection to said outlet connection; and

means for closing said first opening and means for opening said first opening, said means for opening said first opening normally closing said first opening until manually actuated and for reclosing said first opening when manual actuation is terminated so that normal limited flow is only through said second opening until said first opening is manually opened and manually retained open, said means for closing said first opening comprising a valve seat around said first opening and a valve disc movably mounted with respect to said valve seat and spring-urged toward the closed position with respect to said valve seat.

6. The shower flow controller of claim 5 wherein said valve disc is mounted on a valve disc holder and said valve disc holder is mounted on a valve stem so that actuation of said stem moves said valve disc away from said valve seat to open said first opening.

7. The shower flow controller of claim 6 wherein said second opening is in an orifice body and said orifice body is adjustably mounted with respect to said valve disc holder to adjust flow through said second opening.

8. The shower flow controller of claim 6 wherein said valve body has a bonnet thereon and said valve stem has a hub thereon, said hub and said bonnet interengage so that when said hub is rotated said stem is moved to move said valve disc away from said valve seat.

9. The shower flow controller of claim 8 further including a spring urging said stem in a direction to move said valve disc against said valve seat to close said first opening so that manual force must be employed to open and maintain opening of said first opening.

10. The shower flow controller of claim 9 wherein said second opening is adjustable.

11. The shower flow controller of claim 10 wherein said wall separating said inlet connection from said outlet connection has an orifice body therein and said orifice body has an orifice therethrough, said orifice being said second opening.

12. The shower flow controller of claim 11 wherein there is a holder within said valve body and said orifice body is adjustable with respect to said holder to adjust the flow through said orifice in said orifice body.

13. A shower flow controller comprising:

a valve body, an inlet connection on said body for connection to a supply of water under pressure, an outlet connection on said body for connection to a showerhead;

a wall in said body separating said inlet connection from said outlet connection, a first opening in said wall, a valve seat around said first opening, said valve body including a bonnet, a valve stem movably mounted in said bonnet, a valve disc holder mounted on said valve stem, a valve disc mounted on said valve disc holder, said valve stem being movable from a first position where said valve disc engages said valve seat to close said first opening to a second position wherein said valve disc is away from said first opening, resilient means urging said valve disc to its first position, manual means for manually moving said valve disc from its first position to its second position to permit a large flow of water through said valve body; and

a second opening through said wall to permit a limited flow of water from said inlet connection to said outlet connection even when said valve disc is in its first position so that a limited water flow is provided to the showerhead for minimal flow during showering.

14. The shower flow controller of claim 13 wherein said second opening is an orifice within an orifice body, said orifice body being mounted in said wall.

15. The shower flow controller of claim 14 wherein said orifice body is adjustably mounted with respect to said wall and is positioned so that adjustment of said orifice body with respect to said wall controls the flow of water through said second opening.

16. The shower flow controller of claim 15 wherein said orifice body lies adjacent said disc holder so that the position of said orifice body with respect to said disc holder controls water flow through said orifice.

17. The shower flow controller of claim 16 wherein said orifice body is threaded through said wall and there is engagement means on said orifice body, said engagement means being accessible through said inlet connection so that said orifice body can be adjusted and positioned within said wall before installation of said shower valve controller.

18. The shower flow controller of claim 17 wherein said engagement means is a screwdriver slot.

19. The shower flow controller of claim 13 further including a manual external handle manually engageable to move said valve disc to its second position.
