360{20 {11 spray nozzle

Claim 2

Apparatus for producing a radial spray pattern comprising a nozzle housing having an axial bore, a rod disposed in said bore and forming therewith an annular passage adapted to form a hollow cylinder of liquid around said rod, a deflector extending transversely of said bore in the path of said liquid, said deflector having in its under surface an annular channel concentric with said bore, said channel in radial section having a surface extending inwardly into the path of said cylinder of liquid to intercept the same, said surface having a contour to deflect said liquid into a radial path at its outer periphery, whereby the liquid is ejected radially around the entire periphery of said deflector in the form of a spray, said housing being fixed in a plate having a surface conforming to the path of the liquid in said channel and cooperating therewith to form a spray opening around its periphery, said bore in said housing being outwardly flared at its discharge end, and the surface of said plate forming a continuation of said flared surface.

Claim 3

Apparatus as set forth in claim 1 in which the surface of said plate and the surface of said channel cooperate to confine the liquid to a peripheral discharge point.

Claim 4

Apparatus for producing a radial spray pattern comprising a nozzle housing having an axial bore, a rod disposed in said bore and forming therewith an annular passage adapted to form a hollow cylinder of liquid around said rod, a spider supporting said rod and having legs mounted in said bore, means supplying liquid for spraying axially to said bore in advance of said spider to provide axial flow of liquid along said bore, said bore and said rod having uninterrupted surfaces throughout their extent, a deflector mounted on said rod and extending transversely of said bore in the path of said liquid, said deflector having in its under surface an annular channel concentric with said bore, said channel in radial section having a surface extending inwardly into the path of said cylinder of liquid to intercept the same, said surface forming a continuation of the surface of said rod and having a contour to deflect said liquid into a radial path at its outer periphery, whereby the liquid is ejected radially around the entire periphery of said deflector in the form of a spray.

Claim 5

Apparatus for producing a radial spray pattern comprising a nozzle housing having an axial bore, a rod disposed in said bore and forming therewith an annular passage adapted to form a hollow cylinder of liquid around said rod, a spider supporting said rod and having legs mounted in said bore, means supplying liquid for spraying axially to said bore in advance of said spider to provide axial flow of liquid along said bore, said bore and said rod having uninterrupted surfaces throughout their extent, a deflector mounted on said rod and extending transversely of said bore in the path of said liquid, said deflector having in its under surface an annular channel concentric with said bore, said channel in radial section having a surface extending inwardly into the path of said cylinder of liquid to intercept the same, said surface forming a continuation of the surface of said rod and having a contour to deflect said liquid into a radial path at its outer periphery, whereby the liquid is ejected radially around the entire periphery of said deflector in the form of a spray.

Claim 6

Spray apparatus as set forth in claim 3 in which said bore is cylindrical throughout its entire extent.

Claim 7

Spray apparatus as set forth in claim 3 in which the bore in said housing is flared outwardly at its discharge end to conform to the curve of said channel in said transverse plate to form a smoothly confined passage for said liquid to a peripheral discharge opening.
