Abstract
Abstract The invention is directed to a gun for supplying a compressed fluid having a housing defining a passageway for supplying the compressible fluid. A valve is moveably positioned with respect to the passageway for controlling the supply of the compressible fluid. The valve defines an aperture and the valve is moveable with respect to the passageway to vary the position of the aperture with respect to the passageway to control the supply of the compressible fluid. A discharge end is located on one end of the passageway. The discharge end is adapted to receive discharge nozzles for the gun whereby the compressible fluid acts as a driving fluid for different driven fluids or solids. There is also provided a number of attachments which can be utilized with the gun of the present invention.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
198 words
A gun for supplying a compressed fluid comprising: a housing defining a passageway, said passageway defining at least one opening, positioned for supplying a compressible fluid; a valve means moveably positioned with respect to said passageway for controlling the supply of said compressible fluid, said valve means defining an aperture, said valve means being moveable with respect to said passageway to vary the position of said aperture with respect to said passageway to control the supply of said compressible fluid; a rotatable connection means is positioned in one end of said passageway to connect said passageway to a source of compressed fluid, said rotatable connection means including an inner core having a large diameter section that sealingly engages said passageway and a removable clip positioned around said inner core, said removable clip containing at least one pivotable flange having a projection that engages said opening in said passageway to maintain said inner core and said removable clip in said passageway a discharge end located on one end of said passageway, said discharge end adapted to receive discharge nozzles for said spray gun whereby said compressible fluid acts as the driving fluid for different driven fluids and particulate solids.
Claim 2
Dependent Claim
198 words
A gun for supplying a compressed fluid comprising: a housing defining a passageway, said passageway defining at least one opening, positioned for supplying a compressible fluid; a valve means moveably positioned with respect to said passageway for controlling the supply of said compressible fluid, said valve means defining an aperture, said valve means being moveable with respect to said passageway to vary the position of said aperture with respect to said passageway to control the supply of said compressible fluid; a rotatable connection means is positioned in one end of said passageway to connect said passageway to a source of compressed fluid, said rotatable connection means including an inner core having a large diameter section that sealingly engages said passageway and a removable clip positioned around said inner core, said removable clip containing at least one pivotable flange having a projection that engages said opening in said passageway to maintain said inner core and said removable clip in said passageway a discharge end located on one end of said passageway, said discharge end adapted to receive discharge nozzles for said spray gun whereby said compressible fluid acts as the driving fluid for different driven fluids and particulate solids.
Claim 3
Dependent Claim
63 words
The gun of claim 1 wherein said inner core contains at least one cut out section to allow said flange to pivot into said cut out section to allow said connection means to be positioned in said passageway, said flange pivoting from said cut out section to engage said opening in said passageway when said connection means is properly positioned in said passageway.
Claim 4
Dependent Claim
74 words
The gun of claim 2 wherein a step is formed where said projection joins said flange and said step is disposed to engage said large diameter section of said inner core when compressed fluid is supplied to said passageway whereby said large diameter section prevents said flange from pivoting into said cut out section and thereby acts to prevent the disengagement of said connection means when compressed fluid is being supplied to said gun.
Claim 5
Dependent Claim
55 words
The gun of claim 3 wherein said inner core can be positioned when compressed fluid is not being supplied to said gun so that said large diameter section does not engage said step and said flange can be pivoted into said cut out section to allow said connection means to be removed from said passageway.
