Abstract
Abstract Method and apparatus for atomising liquids in which a liquid is fed from an outer, annular, convergent nozzle into a stream of gas fed at sonic velocity from a coaxial inner convergent nozzle. A difergent deflector is positioned coaxially within the outlet openings of the two nozzles.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
152 words
An atomiser, comprising: an annular distributor member, including a radially outer circumferential ring of axial liquid feed passages, and a radially inner circumferential ring of axial gas feed passages; a first annular member, disposed adjacent one end of said distributor member, and including at least one opening therein communicative with said ring of gas feed passages and a plurality of radially outer axial apertures communicative with said ring of liquid feed passages; a deflector member, coupled to said distributor member, extending through said opening in said first annular member, a convergent annular gas nozzle chamber being defined by said first annular member and said deflector member adjacent said ring of gas feed passages; and a second annular member, disposed on said distributor member, and including an opening through which said deflector extends, said first and second annular members defining a convergent annular liquid nozzle chamber adjacent said ring of liquid feed passages.
Claim 2
Dependent Claim
152 words
An atomiser, comprising: an annular distributor member, including a radially outer circumferential ring of axial liquid feed passages, and a radially inner circumferential ring of axial gas feed passages; a first annular member, disposed adjacent one end of said distributor member, and including at least one opening therein communicative with said ring of gas feed passages and a plurality of radially outer axial apertures communicative with said ring of liquid feed passages; a deflector member, coupled to said distributor member, extending through said opening in said first annular member, a convergent annular gas nozzle chamber being defined by said first annular member and said deflector member adjacent said ring of gas feed passages; and a second annular member, disposed on said distributor member, and including an opening through which said deflector extends, said first and second annular members defining a convergent annular liquid nozzle chamber adjacent said ring of liquid feed passages.
Claim 3
Dependent Claim
23 words
The atomiser as recited in claim 1, wherein said second annular member includes a knife-edge disposed about the periphery of said opening therein.
Claim 4
Dependent Claim
30 words
The atomiser as recited in claim 1, wherein said deflector member includes a divergent portion at one end thereof which extends outwardly from said opening in said second annular member.
Claim 5
Dependent Claim
142 words
An atomiser, comprising: an annular distributor member, including a radially outer circumferential ring of axial liquid feed passages, a radially inner circumferential ring of axial gas feed passages, and an outwardly extending annular extension disposed at one end thereof between said inner and outer rings of feed passages; an annular member, disposed on said distributor member, and having a radially inwardly extending edge at one end thereof, said edge of said annular member and said annular extension forming an annular, convergent liquid nozzle chamber adjacent and communicative with said ring of liquid feed passages; and a deflector member, coupled to said distributor member and extending outwardly from one end thereof, said deflector member and said annular extension of said distributor member forming a convergent annular gas nozzle chamber adjacent and communicative with said ring of gas feed passages in said distributor member.
Claim 6
Dependent Claim
142 words
An atomiser, comprising: an annular distributor member, including a radially outer circumferential ring of axial liquid feed passages, a radially inner circumferential ring of axial gas feed passages, and an outwardly extending annular extension disposed at one end thereof between said inner and outer rings of feed passages; an annular member, disposed on said distributor member, and having a radially inwardly extending edge at one end thereof, said edge of said annular member and said annular extension forming an annular, convergent liquid nozzle chamber adjacent and communicative with said ring of liquid feed passages; and a deflector member, coupled to said distributor member and extending outwardly from one end thereof, said deflector member and said annular extension of said distributor member forming a convergent annular gas nozzle chamber adjacent and communicative with said ring of gas feed passages in said distributor member.
Claim 7
Dependent Claim
36 words
The atomiser as recited in claim 4, wherein said deflector member includes a divergent surface, disposed adjacent said annular extension of said distributor member, for forming in conjunction with said extension said convergent gas nozzle chamber.
Claim 8
Dependent Claim
30 words
The atomiser as recited in claim 4, wherein said radially inwardly extending edge of said annular member includes a radially inwardly convergent inner surface for forming said liquid nozzle chamber.
Claim 9
Dependent Claim
78 words
The atomiser as recited in claim 6, wherein said distributor member includes a first threaded portion on the outside surface thereof and a second threaded portion on the Inner surface thereof, said annular member includes a threaded portion on the inner surface thereof for threadably engaging said first threaded portion of said distributor member, and said deflector member including a threaded portion on the outside surface thereof for threadably engaging said second threaded portion of said distributor member.
Claim 10
Dependent Claim
27 words
The atomiser as recited in claim 7, wherein said deflector member includes an additional divergent portion extending outwardly adjacent said inwardly extending edge of said annular member.
