Abstract
Abstract A device for aerating a jet of water, wherein a subdivider member divides the water flow into a number of partial flows and directs said partial flows one against the other such as they impact violently and atomize one another within a chamber wherein exterior air may enter through openings of the body of the device for being absorbed in the atomized jet of water.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
154 words
A device for aerating a jet of water, comprising a tubular body, a sleeve inserted in said body defining a gap between said body and said sleeve, openings formed in said body communicating with said gap and with the exterior air, a subdivider member inserted in said body defining an interior chamber communicating with said gap, said subdivider member having a raised portion of substantially conical shape, and convergent passages in said raised portion of the subdivider member, said passages being inclined with respect to the axis of said tubular body and having a first internal wall substantially parallel to the axis of said tubular body and a second wall substantially perpendicular to the first wall, whereby a flow of water sent to said tubular body through said subdivider member is subdivided into a number of partial flows which converge mutually into said chamber and impact mutually within said chamber to atomize one another.
Claim 2
Independent Claim
154 words
A device for aerating a jet of water, comprising a tubular body, a sleeve inserted in said body defining a gap between said body and said sleeve, openings formed in said body communicating with said gap and with the exterior air, a subdivider member inserted in said body defining an interior chamber communicating with said gap, said subdivider member having a raised portion of substantially conical shape, and convergent passages in said raised portion of the subdivider member, said passages being inclined with respect to the axis of said tubular body and having a first internal wall substantially parallel to the axis of said tubular body and a second wall substantially perpendicular to the first wall, whereby a flow of water sent to said tubular body through said subdivider member is subdivided into a number of partial flows which converge mutually into said chamber and impact mutually within said chamber to atomize one another.
Claim 3
Dependent Claim
41 words
A device as set forth in claim 1, wherein said tubular body has a slightly narrowed discharge opening at the end opposed to said subdivider member, and a recess forming an annular chamber between said discharge opening and said inserted sleeve.
Claim 4
Dependent Claim
37 words
A device as set forth in claim 1, wherein said subdivider member is inserted at one end of said tubular body, said subdivider member being formed of a slightly resilient synthetic material for acting as a seal.
Claim 5
Dependent Claim
28 words
A device as set forth in claim 1, further comprising a jet stabilizer in the form of a ball inserted in the lower portion of said interior chamber.
Claim 6
Dependent Claim
42 words
A device as set forth in claim 1, wherein said subdivider member has an axial shaft, and further comprising a jet stabilizer in the form of a ball, said ball having a hole for insertion onto the free end of said shaft.
Claim 7
Dependent Claim
25 words
A device as set forth in claim 1, further comprising a jet stabilizer in the form of an apertured baffle inserted within said interior chamber.
Claim 8
Dependent Claim
18 words
A device as set forth in claim 1, wherein said tubular body has an apertured baffle integral therewith.
Claim 9
Dependent Claim
17 words
A device as set forth in claim 1, wherein said sleeve has an apertured baffle integral therewith.
Claim 10
Dependent Claim
28 words
A device as set forth in claim 1, wherein said sleeve has a lower extension and, at the lower end of said extension, an apertured baffle integral therewith.
Claim 11
Dependent Claim
35 words
A device as set forth in claim 1, and a jet stabilizer in the form of a ball disposed in the lower portion of said interior chamber, said ball having an apertured baffle integral therewith.
Claim 12
Dependent Claim
37 words
A device as set forth in claim 1, wherein said sleeve has upper extensions in the form of castellations, said extensions being mutually separated by free air passages, and wherein said subdivider member rests on said extensions.
Claim 13
Independent Claim
163 words
A device for aerating a jet of water, comprising a tubular body, a sleeve inserted in said body defining a gap between said body and said sleeve, openings formed in said body communicating with said gap and with the exterior air, a subdivider member inserted in said body defining an interior chamber communicating with said gap, said subdivider member having a raised portion, convergent passages formed in said raised portion of the subdivider member, said convergent passages having a first internal wall substantially parallel to the axis of said tubular body and a second wall substantially perpendicular to the first one, and a deflecting member superimposed to said subdivider member and partially closing said passages except at the lower ends thereof,whereby a flow of water sent to said tubular body through said subdivider member is subdivided in a number of radial partial flows which converge mutually into said chamber and impact mutually within said chamber to atomize one another even by reduced flow.
Claim 14
Independent Claim
163 words
A device for aerating a jet of water, comprising a tubular body, a sleeve inserted in said body defining a gap between said body and said sleeve, openings formed in said body communicating with said gap and with the exterior air, a subdivider member inserted in said body defining an interior chamber communicating with said gap, said subdivider member having a raised portion, convergent passages formed in said raised portion of the subdivider member, said convergent passages having a first internal wall substantially parallel to the axis of said tubular body and a second wall substantially perpendicular to the first one, and a deflecting member superimposed to said subdivider member and partially closing said passages except at the lower ends thereof,whereby a flow of water sent to said tubular body through said subdivider member is subdivided in a number of radial partial flows which converge mutually into said chamber and impact mutually within said chamber to atomize one another even by reduced flow.
Claim 15
Dependent Claim
18 words
A device as set forth in claim 12, wherein said deflecting member has a substantially sharp deflecting edge.
Claim 16
Dependent Claim
33 words
A device as set forth in claim 12, wherein said deflecting member has a number of points opposed to said subdivider member and extending substantially in the axial direction of said tubular body.
Claim 17
Dependent Claim
41 words
A device as set forth in claim 12, wherein said raised portion of the subdivider member is substantially conical and has a central pin, and said deflecting member is substantially frusto-conical and has a central hole for insertion onto said pin.
