Abstract
Abstract A sill cock assembly is disclosed comprising a fluid outlet for location on the exterior of a wall, a fluid flow inlet adapted for location adjacent the interior of the wall, a conduit connecting the fluid inlet and the fluid outlet, a selectively operable valve located adjacent the fluid flow inlet for alternatively opening and closing the fluid flow inlet, and a pressure release means located adjacent the valve to allow fluid communication in an inwardly direction from the conduit through the valve to the fluid inlet when the fluid pressure within the conduit due to freezing is greater than the fluid pressure of the inlet. A portion of the wall of the conduit is corrugated adjacent the valve to allow expansion of the conduit during freezing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
345 words
A sill cock assembly comprising, a fluid flow inlet means, a fluid outlet means, a conduit means fluidly connecting said fluid inlet means and said fluid outlet means, said conduit means having inward and outward ends with said inward end connected to said inlet means and said outward end connected to said outlet means, selectively operable valve means operationally connected to said inlet means and adapted to alternately open and close said inlet means and adapted to alternately permit and prevent fluid flow from said inlet means through said conduit means in an outwardly direction, and pressure relief means located adjacent said valve means to provide fluid communication from said conduit means, through said valve means to said inlet means in an inwardly direction at a predetermined fluid pressure when fluid pressure in said conduit means is greater than fluid pressure in said inlet means, said pressure relef means comprising a passageway extending through said valve means from said conduit means to said inlet means and closure means operationally connected to said passageway, said closure means preventing fluid flow in an outwardly direction through said passageway and allowing fluid flow in an inwardly direction through said passageway at said predetermined fluid pressure within said conduit means, said closure means comprising a valve member seat within said passageway, said valve member seat including an annular inner portion and an annular outer portion positioned radially outwardly of said annular inner portion, and a valve member adjacent said valve member seat, said valve member having annular inner and outer portions adapted to engage said annular inner and outer portions respectively of said valve member seat to prevent fluid flow in an outwardly direction through said passageway, said valve member having an aperture therethrough at a position radially intermediate said inner and outer portions of said valve member so that said predetermined fluid pressure within said conduit means disengages said inner portion of said valve member from said inner portion of said valve member seat allowing fluid flow between said disengaged inner portions, through said aperture and said passageway.
Claim 2
Dependent Claim
345 words
A sill cock assembly comprising, a fluid flow inlet means, a fluid outlet means, a conduit means fluidly connecting said fluid inlet means and said fluid outlet means, said conduit means having inward and outward ends with said inward end connected to said inlet means and said outward end connected to said outlet means, selectively operable valve means operationally connected to said inlet means and adapted to alternately open and close said inlet means and adapted to alternately permit and prevent fluid flow from said inlet means through said conduit means in an outwardly direction, and pressure relief means located adjacent said valve means to provide fluid communication from said conduit means, through said valve means to said inlet means in an inwardly direction at a predetermined fluid pressure when fluid pressure in said conduit means is greater than fluid pressure in said inlet means, said pressure relef means comprising a passageway extending through said valve means from said conduit means to said inlet means and closure means operationally connected to said passageway, said closure means preventing fluid flow in an outwardly direction through said passageway and allowing fluid flow in an inwardly direction through said passageway at said predetermined fluid pressure within said conduit means, said closure means comprising a valve member seat within said passageway, said valve member seat including an annular inner portion and an annular outer portion positioned radially outwardly of said annular inner portion, and a valve member adjacent said valve member seat, said valve member having annular inner and outer portions adapted to engage said annular inner and outer portions respectively of said valve member seat to prevent fluid flow in an outwardly direction through said passageway, said valve member having an aperture therethrough at a position radially intermediate said inner and outer portions of said valve member so that said predetermined fluid pressure within said conduit means disengages said inner portion of said valve member from said inner portion of said valve member seat allowing fluid flow between said disengaged inner portions, through said aperture and said passageway.
Claim 3
Dependent Claim
103 words
The device of claim 1 wherein said valve means comprises a perforated sleeve to threadably engage said inlet means, a valve seat attached to said inlet means, a valve head adapted to alternately engage and disengage said valve seat to prevent and permit fluid flow from said inlet means through said perforated sleeve into said conduit means, said valve head located within said sleeve so that rotation of said sleeve translates said valve head axially within said conduit means, and a shaft member attached to said sleeve and extending outwardly through said conduit means adapted for manually imparting rotational movement to said sleeve.
Claim 4
Dependent Claim
23 words
The device of claim 1 wherein said conduit means comprises a cylindrical pipe having a corrugated portion to allow expansion of said pipe.
