Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
103 words
In a fluid aerating device comprising: an open ended cylindrical member defining an annular inlet passage having a nozzle at its fluid discharge end for transmitting unobstructively said fluid under pressure, walls spaced from the outer circumferential surface of said passage and forming therebetween a second coaxial annular passageway, air inlet means for directing air into said second coaxial annular passageway, said walls being formed to direct air from said second coaxial annular passageway into said passage for aerating fluid passing through said passage; and valve means connected to said air inlet means for controlling the amount of air flowing into said passage.
Claim 2
Dependent Claim
103 words
In a fluid aerating device comprising: an open ended cylindrical member defining an annular inlet passage having a nozzle at its fluid discharge end for transmitting unobstructively said fluid under pressure, walls spaced from the outer circumferential surface of said passage and forming therebetween a second coaxial annular passageway, air inlet means for directing air into said second coaxial annular passageway, said walls being formed to direct air from said second coaxial annular passageway into said passage for aerating fluid passing through said passage; and valve means connected to said air inlet means for controlling the amount of air flowing into said passage.
Claim 3
Dependent Claim
66 words
The fluid aerating device set forth in claim 1 wherein: said walls being provided with a plurality of apertures extending therethrough, and each of said apertures providing a passageway for directing air into said passage from said second coaxial annular passageway for aerating fluid passing through said passage at a plurality of spaced positions without effecting the velocity of the flow of fluid through said passage.
Claim 4
Dependent Claim
25 words
The fluid aerating device set forth in claim 2 wherein said apertures are equally spaced in said wall around the periphery of said inlet passage.
Claim 5
Dependent Claim
62 words
The fluid aerating device set forth in claim 1 wherein said valve means comprises a housing for receiving atmospheric air, said housing having an annular air inlet structure, said structure upon rotation conTrolling the volume of air into said valve means and a porous insert inserted in said housing for muffling the sound of the air flowing into said air inlet means.
Claim 6
Dependent Claim
75 words
The fluid aerating device set forth in claim 1 wherein: said member comprises a T-shaped housing having said annular inlet passage passing in a straight line through a tapered portion leading up to said nozzle in the crossarm of said T-shaped housing, and said air inlet means directing air into the leg of said T-shaped housing, and said valve means being adjustable for manually controlling the amount of air flowing into said air inlet passage.
Claim 7
Dependent Claim
102 words
The fluid aerating device set forth in claim 6 wherein: said member comprises a T-shaped housing having said annular inlet passage passing in a straight line horizontally through said member when installed in a pool, said air inlet means being connected to a leg of said T-shaped housing which extends substantially vertically upward from said T-shaped housing when installed in a pool, said valve means being connected to said air inlet means so as to extend substantially horizontally with said inlet passage, and said valve means and the discharge end of said inlet passage in said member lying within the same plane.
