Abstract
Abstract A fluid coupling system employs a cap assembly and a connector assembly to provide a leakproof fluid coupling between a liquid container and a device requiring liquid. The cap assembly consists of a cap, a filler valve assembly, a spring and a cap gasket. The connector assembly includes a pusher stem and a cap guide which operate to provide a sealed fluid passageway thereby preventing any fluid leakage. A tank bay is also utilized to contain any accidental fluid leakage.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
132 words
A fluid coupling system for connecting a liquid container to a device liquid input port comprising: a cap assembly having a pair of arcuate fluid inlets connected to a first fluid passageway, operative to permit the flow of the liquid from said liquid container; a pusher stem having a second fluid passageway operative to form a single sealed passageway consisting of said first and second fluid passageways, to thereby permit liquid to flow from said liquid container through said arcuate fluid inlets through said single sealed passageway into said liquid input port when said pusher stem presses against said cap assembly; and a cap guide surrounding said pusher stem, said cap guide having a flare at one end and a shoulder approximate to the opposite end, operative to secure said cap assembly.
Claim 2
Dependent Claim
132 words
A fluid coupling system for connecting a liquid container to a device liquid input port comprising: a cap assembly having a pair of arcuate fluid inlets connected to a first fluid passageway, operative to permit the flow of the liquid from said liquid container; a pusher stem having a second fluid passageway operative to form a single sealed passageway consisting of said first and second fluid passageways, to thereby permit liquid to flow from said liquid container through said arcuate fluid inlets through said single sealed passageway into said liquid input port when said pusher stem presses against said cap assembly; and a cap guide surrounding said pusher stem, said cap guide having a flare at one end and a shoulder approximate to the opposite end, operative to secure said cap assembly.
Claim 3
Dependent Claim
63 words
The fluid coupling system of claim 1 wherein said cap assembly further comprises: a cap having a first inner bore and a second inner bore; a filler valve assembly extending from said first inner bore to said second inner bore; and a spring positioned between said filler valve assembly and said first inner bore operative to exert force on said filler valve assembly.
Claim 4
Dependent Claim
24 words
The cap assembly of claim 2 wherein said cap further comprises: a set of threads integrated within the surface of said second cap bore.
Claim 5
Dependent Claim
43 words
The cap assembly of claim 2 wherein said filler valve assembly comprises: a filler stem having a first end and a second end with a shoulder located at said first end; and a seat attached to said second end of said filler stem.
