Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
153 words
A liquid fuel atomizing device for positioning in an airstream comprising: a tubular body formed by an outer sleeve and an inner sleeve defining between them an annular passage for liquid fuel, said inner sleeve being open at both ends so that in use, an airstream can flow through the body; a conical air flow deflector disposed at a downstream end of the body to deflect the airstream through the body; an annular wall bounding said annular passage at the downstream end of the body and formed with a series of spaced holes; an internal annular rib on the body, which is adjacent a free edge of the conical flow deflector and with which the holes in the annular wall are aligned so that liquid fuel issuing through said holes from the annular passage impinges against said rib so as to be directed into the airstream adjacent the free edge of the deflector.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
32 words
A device as claimed in claim 1 in which the tubular body is formed by an outer sleeve and an inner sleeve defining between them an annular passage for the liquid fuel.
