Abstract
Abstract A liquid atomizing nozzle for injecting atomized fuel or water or fuel and water into an internal combustion engine or into a boiler. The nozzle has at least one passage for air and one region where turbulence of air is established and at least one passage with an exit for directing liquid fuel into said region for combustion. The nozzle also may include at least one passage with an exit for directing water into said region. Where there are more than one combustion regions in said engine or boiler, there will be more than one set of passages, turbulence regions and exits, with each second exit directed into a separate combustion region or into a common manifold in the direction of a separate intake of a separate combustion region.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
89 words
A liquid atomizing nozzle for an internal combustion engine comprising a first passage for a high velocity stream of air; a region designed to receive and create resonate turbulence of the air; a second passage for directing liquid into said region for atomization thereof in the turbulent air; and a third exit passage from the region for the atomized liquid, which exit passage is elongated but of restricted area so that the atomized liquid exits as a jet capable of being directed towards an inlet of a combustion chamber.
Claim 2
Dependent Claim
89 words
A liquid atomizing nozzle for an internal combustion engine comprising a first passage for a high velocity stream of air; a region designed to receive and create resonate turbulence of the air; a second passage for directing liquid into said region for atomization thereof in the turbulent air; and a third exit passage from the region for the atomized liquid, which exit passage is elongated but of restricted area so that the atomized liquid exits as a jet capable of being directed towards an inlet of a combustion chamber.
Claim 3
Dependent Claim
25 words
A nozzle as claimed in claim 1 in which said liquid-directing second passage and said third passage are on opposite sides of the turbulence region.
Claim 4
Dependent Claim
18 words
A nozzle as claimed in claim 1 in which the second passage and the third passage are co-axial.
Claim 5
Dependent Claim
32 words
A nozzle as claimed in claim 1 in which the axis of each of the second passage and of the third passage is transverse to the axis of the air stream passage.
Claim 6
Dependent Claim
38 words
A nozzle as claimed in claim 1 wherein said region includes a recess into which said stream of air is directed and from which it is reflected to interfere with the following air stream to set up turbulence.
Claim 7
Dependent Claim
17 words
A nozzle as claimed in claim 1 including passages defining a plurality of each of said passages.
Claim 8
Dependent Claim
22 words
A nozzle as claimed in claim 6 in which there is a separate air passage and turbulence region for each exit passage.
Claim 9
Dependent Claim
29 words
A nozzle as claimed in claim 6 in which pairs of third passages are arranged so that the atomized fluid jets therefrom converge or intersect at a common point.
Claim 10
Dependent Claim
45 words
A nozzle as claimed in claim 8 in which there is a central liquid inlet passage surrounded by air passages and connected to one of each pair of said third passages and in which liquid flows outwardly from the central passage across the turbulence region.
Claim 11
Dependent Claim
64 words
A liquid atomizing nozzle comprising an axial bore for liquid; at least one air bore parallel with the liquid bore and spaced laterally from it and terminating in a resonator chamber; a relatively fine bore connecting the liquid bore with the air bore; and a relatively large bore leading from where the air bore meets said fine bore, all the bores being drilled holes.
Claim 12
Dependent Claim
64 words
A liquid atomizing nozzle comprising an axial bore for liquid; at least one air bore parallel with the liquid bore and spaced laterally from it and terminating in a resonator chamber; a relatively fine bore connecting the liquid bore with the air bore; and a relatively large bore leading from where the air bore meets said fine bore, all the bores being drilled holes.
Claim 13
Dependent Claim
77 words
A liquid atomizing nozzle comprising an axial bore for one liquid; a co-axial annular bore around and spaced from the axial bore for a second liquid; a plurality of annularly spaced bores parallel to and around said annular bore; a resonator turbulence region at the outer end of each of said parallel bores; and alternate exit bores extending from said axial and co-axial bores passing through alternate turbulence regions to provide atomization of each of said liquids.
Claim 14
Dependent Claim
77 words
A liquid atomizing nozzle comprising an axial bore for one liquid; a co-axial annular bore around and spaced from the axial bore for a second liquid; a plurality of annularly spaced bores parallel to and around said annular bore; a resonator turbulence region at the outer end of each of said parallel bores; and alternate exit bores extending from said axial and co-axial bores passing through alternate turbulence regions to provide atomization of each of said liquids.
Claim 15
Dependent Claim
27 words
A liquid atomizing nozzle as claimed in claim 11 wherein said alternate exit bores are in converging pairs to provide directed jets of mixtures of said liquids.
Claim 16
Dependent Claim
25 words
A nozzle as defined in claim 12 wherein the exit bores from the axial bore are axially beyond the exit bores from said co-axial bore.
Claim 17
Dependent Claim
40 words
An internal combustion engine having a nozzle as defined in claim 6 with exit passages arranged so that the atomized fuel jets issuing therefrom are directed into the engine's inlet manifold and each towards an inlet port in separate cylinders.
Claim 18
Dependent Claim
26 words
