Abstract
Abstract An improved water inlet control for toilet tanks of light weight simple construction, has an inverted U-shaped deflector channel for conducting water from an upwardly discharging cutoff valve to a down spout leading into the tank. The water is not forced to change direction abruptly at any point. The open channel itself serves as a true vacuum breaker, without pulling in air during normal operation, and the float controlled valve may function as a check valve when the float is down, thus giving complete assurance against the possibility of back flow if a vacuum should occur in the supply pipe.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
179 words
Water inlet control means for toilet tanks comprising a. a float controlled valve adapted for connection to a supply pipe and having an upwardly directed discharge means located above the high water level of the tank; b. a deflector of inverted U-shape mounted above said valve and Having an inwardly and downwardly opening channel extending throughout its length, the entrance end of said channel being located in line with said discharge means whereby, when said valve is open, a stream is directed tangentially against the inside surface of said channel, the outlet end of said channel being located to one side of said valve, the open sides of said U-shaped deflector being positioned above the high water level; and c. a downwardly extending spout in line with the outlet end of said deflector and adapted to control the flow of water to the lower portion of the tank, the upper portion of said spout being channel shaped and opening laterally inwardly with its inside surface constituting a smooth continuation of the inside surface of the channel of said deflector.
Claim 2
Dependent Claim
179 words
Water inlet control means for toilet tanks comprising a. a float controlled valve adapted for connection to a supply pipe and having an upwardly directed discharge means located above the high water level of the tank; b. a deflector of inverted U-shape mounted above said valve and Having an inwardly and downwardly opening channel extending throughout its length, the entrance end of said channel being located in line with said discharge means whereby, when said valve is open, a stream is directed tangentially against the inside surface of said channel, the outlet end of said channel being located to one side of said valve, the open sides of said U-shaped deflector being positioned above the high water level; and c. a downwardly extending spout in line with the outlet end of said deflector and adapted to control the flow of water to the lower portion of the tank, the upper portion of said spout being channel shaped and opening laterally inwardly with its inside surface constituting a smooth continuation of the inside surface of the channel of said deflector.
Claim 3
Dependent Claim
50 words
Water control means as defined in claim 1, wherein said deflector is mounted so that its U-shaped channel extends vertically and wherein said discharge means is a vertically directed nozzle adapted to direct a stream tangentially against the downwardly facing inside surface of the deflector channel near its entrance end.
Claim 4
Dependent Claim
71 words
Water inlet control means as defined in claim 1, wherein said valve includes a body having a plurality of concentric vertical bores, a vertically movable plunger fitted in the upper bore and having vertical passages leading directly to said nozzle which is at the upper end of said plunger, whereby the combination of valve, deflector and spout allows flow through the entire inlet control means without any abrupt change of direction.
Claim 5
Dependent Claim
33 words
Water inlet control means as defined in claim 1, wherein said float controlled valve is a ball type valve which may act as a check valve to prevent backflow into the supply pipe.
Claim 6
Dependent Claim
55 words
Water inlet control means as defined in claim 4, wherein said float controlled valve has a valve body with an upwardly opening cylindrical bore, a plunger slidably fitted in said bore, said plunger being generally hollow to provide flow passage without abrupt change of direction, said plunger also having a centrally located ball control cage.
Claim 7
Dependent Claim
39 words
In combination with water inlet control means as defined in claim 1, a refill tube connection including a boss formed on said deflector, said boss having a passage which leads tangentially in a downstream direction from the deflector channel.
Claim 8
Dependent Claim
40 words
Water inlet control means as defined in claim 1, wherein said float controlled valve has a float carrying arm extending to one side of said valve, said deflector extending from said valve at an angle to said float carrying arm.
