Abstract
Abstract An atomizer for atomizing liquid fuels for combustion consisting of an outer, annular liquid nozzle chamber which converges towards an annular outlet therefrom and a coaxial, inner gas nozzle chamber which converges towards an annular outlet therefrom. A rigid annular deflector member is positioned coaxially with respect to the outlet openings and extends at least from the outlet openings to a position downstream of such openings. The deflector member also has a gas bleed duct leading to a further deflector arranged so as to deflect a gas stream across the outer end face of the deflector member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
106 words
An atomizer comprising an outer, annular liquid nozzle chamber which converges towards an annular outlet therefrom, a coaxial, inner gas nozzle chamber which converges towards an annular outlet therefrom, a rigid annular deflector member positioned coaxially with respect to said outlet openings and extending at least from said outlet openings to a point downstream of said outlet openings, a further deflector arranged spaced apart from and coplanar with the outer end surface of the deflector member and a gas bleed duct formed in the deflector member so as to lead from a gas supply duct to the space between the deflector member and further deflector member.
Claim 2
Dependent Claim
106 words
An atomizer comprising an outer, annular liquid nozzle chamber which converges towards an annular outlet therefrom, a coaxial, inner gas nozzle chamber which converges towards an annular outlet therefrom, a rigid annular deflector member positioned coaxially with respect to said outlet openings and extending at least from said outlet openings to a point downstream of said outlet openings, a further deflector arranged spaced apart from and coplanar with the outer end surface of the deflector member and a gas bleed duct formed in the deflector member so as to lead from a gas supply duct to the space between the deflector member and further deflector member.
Claim 3
Dependent Claim
37 words
An atomizer as claimed in claim 1 wherein the gas bleed duct and arrangement of further deflector are such as to provide said gas stream at approximately one third of the operating gas pressure of the atomizer.
Claim 4
Dependent Claim
30 words
An atomizer as claimed in claim 1 wherein the diameter of the further deflector is approximately one half of the diameter of the outer end face of the deflector member.
Claim 5
Dependent Claim
25 words
An atomizer as claimed in claim 1 wherein the further deflector comprises an insert which is mounted in a central aperture in the deflector member.
Claim 6
Dependent Claim
27 words
An atomizer as claimed in claim 1 wherein the further deflector is spaced between 0.004 and 0.007 inches from the outer end face of the deflector member.
