Fluid valve
DCFirst Claim
1. A fluid valve cartridge, said valve cartridge comprising:
- a self-contained cartridge housing configured to be received by a water fixture and having an entrance to permit flow of fluid into said housing and an exit to permit said fluid to flow out of said housing;
a first member defining at least one first passageway;
a second member defining at least one second passageway,said first member and said second member being disposed in said housing operatively between said entrance and said exit so that said at least one first passageway and said at least one second passageway are selectively positionable with respect to each other to allow passage of said fluid through said at least one first passageway and said at least one second passageway from said entrance to said exit;
a check valve disposed in said housing operatively between said entrance and said first and second members, said check valve being configured to permit fluid flow from said entrance to said first and second members and to prevent fluid flow from said first and second members out of said housing by said entrance; and
a retainer axially secured to said housing operatively between said check valve and said first and second members to prevent axial movement of said check valve to said first and second members.

Abstract
A fluid valve is provided including a housing having an entrance to permit flow of fluid into the housing and an exit to permit said fluid to flow out of the housing. A first member is disposed in the housing and defines at least one first passageway. A second member is disposed in the housing and defines at least one second passageway. The first member and the second member are disposed in the housing operatively between the entrance and the exit so that the at least one first passageway and the at least one second passageway are selectively positionable with respect to each other to allow passage of the fluid through the at least one first passageway and the at least one second passageway from the entrance to the exit. A check valve is disposed in the housing operatively between the entrance and the first and second members. The check valve is configured to permit fluid flow from the entrance to the first and second members and to prevent fluid flow from the first and second members out of the housing by the entrance.

21. A fluid valve cartridge, said valve comprising:
-
a housing having an entrance to permit flow of fluid into said housing and an exit to permit said fluid to flow out of said housing; a first member defining at least one first passageway; a second member defining at least one second passageway, said first member and said second member being disposed in said housing operatively between said entrance and said exit so that said at least one first passageway and said at least one second passageway are selectively positionable with respect to each other to allow passage of said fluid through said at least one first passageway and said at least one second passageway from said entrance to said exit; a check valve disposed in said housing operatively between said entrance and said first and second members, said check valve being configured to permit fluid flow from said entrance to said first and second members and to prevent fluid flow from said first and second members out of said housing by said entrance; and a resilient seat assembly disposed in said housing operatively between said entrance and said first and second members in operative communication with said first and second members to absorb forces applied to at least one of said first and second members, wherein said resilient seat assembly includes a resilient annular portion operatively disposed between said check valve and said first and second members, said resilient annular portion sealingly engaging one of said first member and said second member to provide a sealed fluid path from said check valve to said one of said first member and said second member, wherein said resilient seat assembly includes a rigid or semi-rigid annular member and wherein said resilient annular portion is disposed about the outer circumference of said rigid or semi-rigid annular member.

22. A fluid valve cartridge, said valve cartridge comprising:
-
a self-contained cartridge housing configured to be received by a water fixture and defining a generally cylindrical interior area having an entrance to permit flow of fluid into said housing and an exit to permit said fluid to flow out of said housing; a first generally cylindrical plate disposed in said housing operatively between said entrance and said exit, said first plate defining at least one first passageway; a second generally cylindrical plate disposed in said housing operatively between said entrance and said exit and abutting said first plate, said second plate defining at least one second passageway, wherein at least one of said first plate and said second plate is rotatable with respect to the other of said first plate and said second plate to position said at least one first passageway and said at least one second passageway with respect to each other to allow passage of said fluid through said at least one first passageway and said at least one second passageway from said entrance to said exit; a check valve disposed in said housing operatively between said entrance and said first and second plates, said check valve being configured to permit fluid flow from said entrance to said first and second plates and to prevent fluid flow from said first and second plates out of said housing by said entrance; and a resilient seat assembly disposed in said housing between said entrance and said first and second plates in operative communication with said first and second plates to absorb forces applied to at least one of said first and second plates, wherein said resilient seat assembly includes a resilient annular portion sealingly engaging one of said first plate and said second plate to provide a sealed fluid path from said check valve to said one of said first plate and said second plate and also includes a rigid or semi-rigid retainer restrained from axial movement to said one of said first plate and said second plate by said resilient annular portion to prevent axial movement of said check valve to said one of said first plate and said second plate. - View Dependent Claims (23, 24, 25, 26, 27, 28)

29. A fluid fixture, said fixture comprising:
-
a housing including at least one fluid path and at least one fluid outlet; and at least one valve cartridge disposed in said housing, each said valve cartridge including a self-contained valve cartridge housing having an entrance in communication with a said fluid path to permit flow of fluid into said valve housing and an exit in communication with a said outlet to permit said fluid to flow out of said valve housing to said outlet, a first member defining at least one first passageway, a second member defining at least one second passageway, said first member and said second member being disposed in said valve housing operatively between said entrance and said exit so that said at least one first passageway and said at least one second passageway are selectively positionable with respect to each other to allow passage of said fluid through said at least one first passageway and said at least one second passageway from said entrance to said exit, and a check valve disposed in said valve housing operatively between said entrance and said first and second members, said check valve being configured to permit fluid flow from said entrance to said first and second members and to prevent fluid flow from said first and second members out of said valve housing by said entrance, and a retainer axially secured to said housing operatively between said check valve and said first and second members to prevent axial movement of said check valve to said first and second members. - View Dependent Claims (30)
