Rotatable wedge cartridge valve mechanism and method for assembly and disassembly
First Claim
1. A rotatable wedge cartridge valve mechanism, comprising:
- a valve body defining a valve chamber of a defined internal width having flow passages in communication with said valve chamber;
a rotatable wedge valve cartridge assembly having a cartridge housing being removably positioned within said valve chamber and having a controllable width,said rotatable wedge valve cartridge assembly having a core member defining a substantially spherical outer surface portion;
a valve seat being located within said cartridge chamber; and
a rotatable wedge valve member being mounted for rotation about said substantially spherical outer surface portion of said core member, and having an external convex surface being disposed in controlled interference engagement with said valve seat and defining a non-uniform wall thickness.

Abstract
A rotatable wedge cartridge valve has a cartridge body defining a cartridge chamber of a defined internal width having flow ports in communication with the cartridge chamber. A rotatable wedge valve cartridge assembly is removeably positioned within the cartridge chamber and has a controllable width. A core member defines a flow passage and has a spherical outer surface portion. A valve seat is located within the cartridge chamber. A rotatable wedge valve member is mounted for rotation relative to the core and has a concave surface portion in rotary guided relation with the spherical outer surface. The rotatable wedge valve member also has an external convex surface that is positioned for sealing engagement with the valve seat and has a geometry developing a non-uniform wall thickness along the rotatable wedge valve member.

9. A method for assembling a rotatable wedge valve cartridge within a cartridge chamber of a defined width, said rotatable wedge valve cartridge having an elongate core member and a rotatable wedge valve member having rotational engagement with said elongate core member, and a valve seat within said cartridge chamber, said method comprising:
-
positioning said elongate core member in inclined relation defining a cartridge width less than said defined width; inserting said rotatable wedge valve cartridge into said cartridge chamber; and moving said elongate tubular core member from said inclined position to a substantially horizontal position increasing said cartridge width to an effective width greater than said defined width and securing said rotatable wedge valve cartridge within said cartridge chamber. - View Dependent Claims (10, 11)

12. A rotatable wedge cartridge valve mechanism, comprising:
-
a valve body defining a valve chamber of a defined internal width and having flow ports in communication with said valve chamber; a rotatable wedge valve cartridge assembly being removeably positioned within said valve chamber and having a controllable width, said valve cartridge assembly having a cartridge housing and having a core member defining a flow passage and having a substantially spherical outer surface portion; a valve seat being located within said cartridge housing; a rotatable wedge valve member defining leading and trailing portions and having a concave surface portion in rotary guided relation with said substantially spherical outer surface, said rotatable wedge valve member having an external convex surface being disposed for sealing engagement with said valve seat and having a non-uniform wall thickness along said rotatable wedge valve member from said leading portion to said trailing portion; and trunnion and operating stem members supporting said rotatable wedge valve member for rotation within said valve chamber and about said substantially spherical outer surface portion of said core member. - View Dependent Claims (13, 14, 15, 16, 17, 18)
