Valve for a pot filler faucet
The valve is threaded onto the pot filler faucet and is opened and closed by turning of the hand wheel secured to the nozzle either clockwise or counter-clockwise. The ceramic valve discs within the valve have pairs of passages that provide either opening or closing of the valve for each 90° turn of the hand wheel. A spring actuated plunger between the valve body and the rotatable nozzle provides an audible sound when moved into a recess in a flange of the nozzle.
1. A valve for a pot filler faucet comprising
an internally threaded body for securement to a pot filler faucet to receive a flow of water therefrom;
a collar fixedly mounted concentrically on said body;
a nozzle rotatably mounted in said collar coaxially of said body for receiving a flow of water from said body;
a pair of mutually rotatable valve discs coaxially of said nozzle that cooperate to allow a flow of water from said body to said nozzle in one relative position and to block a flow of water in a second relative position, one of said valve discs being disposed in said body in stationary relation and defining a pair of diametrically disposed passages for passage of water therethrough and the other of said valve discs being disposed in said nozzle in stationary relation and in contact with the first valve disc and defining a pair of passages for selective alignment with said passages in said one valve disc; and
a hand wheel secured to and concentrically of said nozzle for rotating said nozzle relative to said body.
2. A valve as set forth in claim 1 wherein each said valve disc is made of ceramic.
3. A valve as set forth in claim 1 wherein said nozzle has an annular flange disposed between said body and said collar.
4. A valve as set forth in claim 3 further comprising a plunger mounted in said body, a spring biasing said plunger against said flange and a recess in said flange for receiving said plunger in a predetermined position of said nozzle relative to said body.
5. A valve as set forth in claim 1 further comprising an orifice aerator disposed coaxially in said nozzle for straightening a flow of water through said nozzle.
6. A valve as set forth in claim 1 wherein said second relative position is disposed 90° from said one relative position.
7. A valve as set forth in claim 6 wherein said nozzle has an annular flange disposed between said body and said collar.
8. A valve as set forth in claim 7 further comprising a plunger mounted in said body, a spring biasing said plunger against said flange and a pair of recesses in said flange disposed 90° from each other for selectively receiving said plunger in a respective closed position of said valve and an open position of said valve.
9. A valve as set forth in claim 1 further comprising a flow restrictor in said body for restricting a flow of water into said body and a screen upstream of said flow restrictor for screening the flow of water into said body.
