Abstract

A sanitary fitting of the type that is used to connect, in back-to-back relationship, a hot and cold water source without the necessity of crossing the pipe connections, is disclosed. The sanitary fitting includes a valve assembly which, when mounted in back-to-back relation with another sanitary fitting, the valving mechanism is arranged and constructed to reverse the flow of hot and cold water through the valve, so that the fitting can be operated in its normal mode, for example, when the handle is in the left-hand position, the hot water flows and, when the handle is in the right-hand position, cold water flows.

Claims

1. A sanitary fitting adapted to be mounted in back-to-back relation to a standard sanitary fitting on the opposite side of a partition wall with the handle operation unchanged, without requiring cross-over connections of the cold and hot water lines, said fitting comprising:

a stationary valve plate having first and second water inlet openings for conducting cold and hot water respectively therethrough and an outlet opening, said plate having a polished surface defining a valve seat;

a shiftable valve plate having means for effecting an internal reversal of water flow through said sanitary fitting, said means including a bifurcated recess formed therein and defining first and second arm sections, for communicating with said first and second water inlet openings respectively;

said shiftable valve plate having a polished surface and being mounted in face-to-face contact with said polished surface, of said stationary valve plate effecting a watertight seal therebetween; and

a valve actuator means rotatably mounted on said sanitary fitting, and coupled to said shiftable valve plate, said actuator means being moveable along the vertical axis of said sanitary fitting for moving said shiftable valve plate rectilinearly so that at least one of said arm sections of said bifurcated recess uncovers said corresponding water inlet opening of said stationary valve plate and, when rotated, said other arm section of said bifurcated recess uncovers said other corresponding water inlet opening of said stationary valve plate.

2. The sanitary fitting of claim 1, wherein said stationary valve plate and said shiftable valve plate are made of ceramic material.

3. The sanitary fitting of claim 1, wherein said fitting includes a casing for housing said stationary and shiftable valve plates, and a cover for sealing said valve plates in operative position, said cover including an actuator arm coupled to said shiftable valve plate.

4. A replaceable cartridge valve for a sanitary fitting having a valving mechanism with a cold and hot water cross-over means which is adapted to be mounted in back-to-back relation to a standard sanitary fitting on the opposite side of a partition wall, with the mode of handle operation unchanged, and without requiring cross-over connections of the cold and hot water lines, said replaceable cartridge valve comprising:

a casing having first and second water inlet openings and an outlet opening at one end, and open at the other end thereof;

a cover for closing said open end of said casing;

a stationary valve plate mounted in said casing and having first and second water inlet openings for conducting cold and hot water respectively therethrough and a water outlet opening, and being aligned with said first and second inlet and outlet casing openings, said valve plate having a polished surface defining a valve seat;

a shiftable valve plate having means for effecting an internal reversal of water flow through said sanitary fitting, said means including a bifurcated recess formed therein and first and second arm sections for communicating with said first and second water inlet openings respectively of said stationary valve plate and said casing;

said shiftable valve plate having a polished surface and being mounted in face-to-face contact with said polished surface of said stationary valve plate to effect a watertight seal therebetween; and

valve actuator means rotatably mounted in said cover and coupled to said shiftable valve plate, said valve actuator means being moveable along the vertical axis of said casing for moving said shiftable valve plate rectilinearly so that at least one of said arm sections of said bifurcated recess uncovers said corresponding water inlet opening of the stationary valve plate and, when rotated, said other arm section of said bifurcated recess uncovers said other corresponding water inlet opening of the stationary valve plate.
