Abstract

A water inlet member is secured extending upwardly into a water tank and is telescoped by a water outlet member with a valve assembly secured to the inlet member and overlying an upper edge of the outlet member providing valve control communication between the inlet member and interiorly of the outlet member. During assembly, a valve housing member is pressed onto the inlet member and simultaneously tightly engages a thin, continuously circular upper edge of the outlet member sealing therebetween. The outlet member includes an angularly upwardly extending refill hose connection spaced downwardly from the outlet member upper edge and above main water outlet openings, a series of spaced fingers being positioned filtering water passing out the refill hose connection. A guide on the valve assembly mounts a float controlling the valve operation and a refill hose extends from the refill hose connection upwardly into a refill tube.

Claims

1. In a ball cock for controlling the flow of water into and the water level within a water tank;

said ball cock being of the type having a water inlet member, a valve assembly pressed onto an end of said water inlet member receiving water centrally into a valve housing thereof over an annular valve seat and from said housing through housing outlet openings, said housing outlet openings directing said water reversely around an outer side of said water inlet member, and a float operably connected to sealing means of said valve assembly for controlling the flow of water over said valve seat and from said housing outlet openings;

then improvements comprising;

a water outlet member telescoped surrounding said water inlet member having an annular end underlying said valve housing outwardly of said housing outlet openings, said outlet member end forming a circular edge tightly abutting said valve housing and sealing against said valve housing during said pressing of said valve assembly onto said water inlet member end, the positioning of said outlet member end forming a water outlet chamber between said inlet and outlet members communicating with said valve housing outlet openings, water outlet openings through said water outlet member spaced from said valve housing and water outlet chamber to internally of said water tank, and refill hose outlet means through said water outlet member spaced from said outlet member end and between said valve housing and said outlet member outlet openings, said refill hose outlet means being adapted for connection to a refill hose extending generally by said valve assembly and into a refill tube of said water tank, said refill hose outlet means including series of closely spaced fingers within said water outlet chamber of said outlet member overlying a refill hose outlet communicating through said outlet member and said fingers being positioned in said outlet member outlet chamber spaced from said outlet member end and between said valve housing and said outlet member outlet openings.

2. A ball cock as defined in claim 1 in which said refill hose outlet means includes said refill hose outlet extending angularly through said outlet member and angularly generally toward said valve assembly.

3. A ball cock as defined in claim 1 in which said water inlet member and said valve housing are formed of metal;

in which said water outlet member is formed of plastic;

in which said outlet member ends includes a continuously circular, thin sealing ring formed integrally thereon and forming said circular edge Tightly abutting said valve housing and sealing against said valve housing; and

in which said refill hose outlet means includes said refill hose outlet extending angularly through said outlet member and angularly generally toward said valve assembly.
