Abstract
Abstract A nozzle for atomizing liquid media, in particular a fan-jet nozzle, comprising a nozzle housing determining by its external dimensions and its fitting means the particular nozzle type, and a nozzle internal structure enclosed by the nozzle housing in turn determining the nozzle type functionally, both the nozzle housing and the nozzle inner structure being made of the same material. The nozzle housing on one hand and on the other the nozzle inner structure (nozzle inset) are separate integral parts, and the nozzle inset is force-fitted in undetachable manner into the nozzle housing. Such separate manufacture of the nozzle housing on one hand and on the other the nozzle inset determining the nozzle inner geometry (functional geometry) allows improving applicability and storage costs while simultaneously lowering the manufacturing and storage costs of said nozzle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
167 words
A fan-jet nozzle for atomizing liquid media, comprising: (a) a nozzle housing means forming an exterior shell having a first end for connection to a fluid supplying means, (b) said nozzle housing means having an interior cylindrical cavity extending from said first end, (c) said nozzle housing means having a second end, (d) said second end having a slot formed therein extending from said second end to said cavity, (e) said nozzle housing means having a rest surface formed where said slot meets said cavity, (f) a nozzle inset means for atomizing a liquid media, (g) said nozzle inset means is undetachably press-fitted within said cylindrical cavity, (h) said nozzle inset means has formed therein a hollow chamber and having a liquid media receiving opening at one end and a smaller liquid media discharge opening at a second end, (i) said discharge opening is positioned to expel atomized liquid media through said slot, (j) said nozzle inset means having a flat end-face which engages said rest surface.
Claim 2
Dependent Claim
167 words
A fan-jet nozzle for atomizing liquid media, comprising: (a) a nozzle housing means forming an exterior shell having a first end for connection to a fluid supplying means, (b) said nozzle housing means having an interior cylindrical cavity extending from said first end, (c) said nozzle housing means having a second end, (d) said second end having a slot formed therein extending from said second end to said cavity, (e) said nozzle housing means having a rest surface formed where said slot meets said cavity, (f) a nozzle inset means for atomizing a liquid media, (g) said nozzle inset means is undetachably press-fitted within said cylindrical cavity, (h) said nozzle inset means has formed therein a hollow chamber and having a liquid media receiving opening at one end and a smaller liquid media discharge opening at a second end, (i) said discharge opening is positioned to expel atomized liquid media through said slot, (j) said nozzle inset means having a flat end-face which engages said rest surface.
Claim 3
Dependent Claim
44 words
The fan-jet nozzle as defined in claim 1, wherein: (a) said discharge opening forms a V-shaped aperture and, (b) said V-shaped aperture is aligned with said slot so that atomized liquid media may flow unimpeded through said nozzle housing means from said discharge opening.
Claim 4
Dependent Claim
21 words
The fan-jet nozzle as defined in claim 2 wherein: (a) said V-shaped aperture is parallel and axially symmetric to said slot.
Claim 5
Dependent Claim
31 words
The fan-jet nozzle as defined in claim 3 wherein: (a) said discharge opening of said nozzle inset means extends through said second cylindrical cavity and protrudes from said nozzle housing means.
Claim 6
Dependent Claim
63 words
The fan-jet nozzle of claim 3, wherein: (a) said nozzle housing means extends beyond said discharge opening, and (b) said nozzle housing means includes a slot milled in said second end, (c) said discharge opening forms an elongated groove, (d) said slot is aligned with said groove so that the flow of atomized liquid media is not impeded by said nozzle housing means.
Claim 7
Dependent Claim
114 words
A fan-jet nozzle for atomizing liquid media, comprising: (a) a nozzle housing means forming an exterior shell having a first end adapted for connection to a fluid supplying means, (b) said nozzle housing means having a cylindrical interior bore of constant diameter extending therethrough from said first end to a second end thereof, (c) nozzle inset means for atomizing a liquid media, (d) said nozzle inset means having formed therein a hollow chamber and having a liquid media receiving opening at a firs end thereof and a discharge opening at a second end thereof, (e) whereby, said nozzle inset means is press-fitted within said bore and said discharge opening extends outwardly from said bore.
Claim 8
Dependent Claim
114 words
A fan-jet nozzle for atomizing liquid media, comprising: (a) a nozzle housing means forming an exterior shell having a first end adapted for connection to a fluid supplying means, (b) said nozzle housing means having a cylindrical interior bore of constant diameter extending therethrough from said first end to a second end thereof, (c) nozzle inset means for atomizing a liquid media, (d) said nozzle inset means having formed therein a hollow chamber and having a liquid media receiving opening at a firs end thereof and a discharge opening at a second end thereof, (e) whereby, said nozzle inset means is press-fitted within said bore and said discharge opening extends outwardly from said bore.
Claim 9
Dependent Claim
171 words
A fan-jet nozzle for atomizing liquid media, comprising: (a) a nozzle housing means forming an exterior shell having a first end adapted for connection to a fluid supplying means, (b) said nozzle housing means having a first interior cylindrical cavity extending from said first end, (c) said nozzle housing means having a second interior cylindrical cavity extending from a second end thereof to said first cylindrical cavity, (d) said second cylindrical cavity being of smaller diameter than said first cylindrical cavity so that a step is formed in the interior of said nozzle housing means, (e) a nozzle inset means for atomizing a liquid media, (f) said nozzle inset means has formed therein a hollow chamber and having a liquid media receiving opening at a first end and a smaller discharge opening at a second end, (g) said nozzle inset means having a flange extending outwardly from said liquid media receiving opening, (h) whereby said nozzle inset means is press-fitted within said second cylindrical cavity and said flange engages said step.
