Valve housing for cartridge type faucets

The combination of a cartridge type valve assembly and a housing for removably receiving said valve assembly while retaining adjustability of the turning torque for operating the valve independently of seating said valve assembly in said housing, comprising:

• said housing being integrally formed and having a generally elongated tubular exterior wall adapted to be vertically disposed, said tubular exterior wall having an open upper end which is interiorly threaded, said exterior wall having an opening formed therein about midway of its length to provide an outlet port;
• said housing also including an interior tubular wall which is concentric to and spaced inwardly from said exterior wall and which extends from said outlet port downwardly to said lower end of said exterior wall, said housing at its lower end having a radially extending wall which circumferentially joins the lower ends of said interior and exterior walls, thereby forming an annular cavity between said interior and exterior walls;
• said valve assembly having a threaded base received in said interiorly threaded upper end of said exterior wall of said housing, said valve assembly being of the disc type and having a lower end which projects into said interior wall and has a disc retainer threadably supported thereon which may be axially adjusted for adjusting the turning torque for operating the valve, and for removal and replacement of the discs of said valve assembly;
• the interior surface of the upper end portion of said interior wall being drilled to a larger diameter than the interior surface of the lower end thereof, and said valve assembly lower end extending into the drilled portion of said interior wall but not the full length of said drilled portion, so that said lower end of said valve assembly is slidably and sealingly received therein with room for axial adjustment by threadably advancing or retreating said threaded base along said lower end of said valve assembly and thereby permitting selected adjustment of the turning torque between the discs of said valve assembly for operation of the valve;
• and
• the open lower end of said interior wall providing an inlet port, and said annular cavity providing a reservoir into which liquid may flow after passing from said inlet port through said valve assembly and before passing to said outlet port.
