Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 74 words
Paint-spraying apparatus comprising: an atomizing nozzle mounted downstream of a source of paint and compressed air, said nozzle having a body with inlet and outlet ends and an axial flow passage extending therebetween, and at least one pair of coaxial radial holes into said passage spaced 180* apart intermediate said ends, and a perforated reflector mounted between said source and said nozzle, said paint and air being supplied to said nozzle through said reflector.
Claim 2
Dependent Claim 74 words
Paint-spraying apparatus comprising: an atomizing nozzle mounted downstream of a source of paint and compressed air, said nozzle having a body with inlet and outlet ends and an axial flow passage extending therebetween, and at least one pair of coaxial radial holes into said passage spaced 180* apart intermediate said ends, and a perforated reflector mounted between said source and said nozzle, said paint and air being supplied to said nozzle through said reflector.
Claim 3
Dependent Claim 32 words
The apparatus of claim 1 wherein said reflector has an axial opening and additional openings arranged symmetrically at opposite sides of said axial opening, said paint being supplied through said axial opening.
Claim 4
Dependent Claim 36 words
The apparatus of claim 1 wherein said reflector is arranged so that at least the major volume of said air is supplied through zones out of angular alignment with said radial holes of said one pair.
Claim 5
Dependent Claim 26 words
The apparatus of claim 2, wherein said openings in said reflector have centers in a single plane perpendicular to the common axis of said radial holes.
Claim 6
Dependent Claim 24 words
The apparatus of claim 2 wherein openings are provided in said reflector adjacent said axial opening to partially relieve the hydraulic pressure drop thereacross.
Claim 7
Dependent Claim 95 words
Paint-spraying apparatus comprising: an atomizing nozzle mounted downstream of a source of paint and compressed air, said nozzle having a body with inlet and outlet ends and an axial flow passage therebetween, and at least one pair of coaxial radial holes into said passage spaced 180* apart intermediate said ends, said holes of said one pair each being larger than any other said radial holes, whereby a fan-shaped spray is produced at said outlet end, the long dimension of said fan being perpendicular to the common axis of said radial holes of said one pair.
Claim 8
Dependent Claim 95 words
Paint-spraying apparatus comprising: an atomizing nozzle mounted downstream of a source of paint and compressed air, said nozzle having a body with inlet and outlet ends and an axial flow passage therebetween, and at least one pair of coaxial radial holes into said passage spaced 180* apart intermediate said ends, said holes of said one pair each being larger than any other said radial holes, whereby a fan-shaped spray is produced at said outlet end, the long dimension of said fan being perpendicular to the common axis of said radial holes of said one pair.
Claim 9
Dependent Claim 17 words
The apparatus of claim 6 wherein there is a single coaxial pair only of said radial holes.
Claim 10
Dependent Claim 40 words
The apparatus of claim 6 wherein a pair of openings are provided into said axial passage at said inlet end arranged symmetrically at opposite sides of the nozzle axis and respectively angularly aligned with said one pair of radial holes.
Claim 11
Dependent Claim 20 words
The apparatus of claim 8 wherein each said inlet end opening has the shape of a segment of a circle.
Claim 12
Dependent Claim 26 words
The apparatus of claim 8 wherein said inlet end openings each have an area larger than that of a said radial hole of said one pair.
Claim 13
Dependent Claim 35 words
The apparatus of claim 8 further comprising an axial inlet hole to said axial passage of area less than that of either said inlet end opening and either said radial hole of said one pair.
