Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
154 words
Paint-spraying apparatus comprising an air cap adapted to be secured to a conventional compressed-air paint-spraying gun adjacent separate paint and air outlets therefrom, said air cap having a portion defining an outlet, and a chamber upstream of said air cap outlet for receiving air and paint from said separate outlets, and an atomizing nozzle mounted in said chamber adjacent said air cap outlet and comprising a body defining an axial flow passage having inlet and outlet ends, and a pair of coaxial radial holes into said passage spaced 180* apart intermediate said ends, said inlet end of said axial flow passage and said coaxial radial holes each being in communication with both said paint and air outlets, whereby said paint and air received in said chamber pass into said flow passage at said inlet end and through said radial holes, and emerge from said air cap outlet, said paint emerging atomized in a spray.
Claim 2
Dependent Claim
154 words
Paint-spraying apparatus comprising an air cap adapted to be secured to a conventional compressed-air paint-spraying gun adjacent separate paint and air outlets therefrom, said air cap having a portion defining an outlet, and a chamber upstream of said air cap outlet for receiving air and paint from said separate outlets, and an atomizing nozzle mounted in said chamber adjacent said air cap outlet and comprising a body defining an axial flow passage having inlet and outlet ends, and a pair of coaxial radial holes into said passage spaced 180* apart intermediate said ends, said inlet end of said axial flow passage and said coaxial radial holes each being in communication with both said paint and air outlets, whereby said paint and air received in said chamber pass into said flow passage at said inlet end and through said radial holes, and emerge from said air cap outlet, said paint emerging atomized in a spray.
Claim 3
Dependent Claim
27 words
The apparatus of claim 1 wherein said air cap has an end wall defining a single outlet opening aligned with a single outlet opening of said Nozzle.
Claim 4
Dependent Claim
28 words
The apparatus of claim 2 wherein said nozzle has a flange surrounding said nozzle outlet opening, and said nozzle is mounted with said flange against said end wall.
Claim 5
Dependent Claim
27 words
The apparatus of claim 2 wherein said outlet opening of said air cap is of diameter at least as great as that of said nozzle outlet opening.
Claim 6
Dependent Claim
22 words
The apparatus of claim 4 wherein said outlet opening of said air cap is of greater diameter than said nozzle outlet opening.
Claim 7
Dependent Claim
30 words
The apparatus of claim 3 wherein said chamber is an axial passage in said air cap of diameter greater than that of said nozzle body just upstream of said flange.
Claim 8
Dependent Claim
22 words
The apparatus of claim 1 wherein a perforated reflector is mounted in said air cap at the upstream end of said chamber.
