Abstract
Abstract A spray nozzle is provided for producing predetermined spray patterns of fan shaped configuration characterized in having an internal body configuration which is uniquely capable of effecting a very wide angled dispersion pattern of uniform density. The body of this spray nozzle is of disc shape having an outlet or a discharge end-face disposed transversely to a fluid flow axis through the body. An elongated, channel-shaped recess is formed in this discharge end portion and opens outwardly from the end face in transversely oriented relationship to the flow axis. A spray pattern control chamber is formed in the body along the flow axis thereof having an inlet at an end-face opposite the discharge end of the body and an outlet disposed interiorally of the body and in fluid communicating relationship with the channel-shaped recess. This spray pattern control chamber is formed with axially extending sidewall portions that are laterally spaced and are relatively convergent at the outlet end. These sidewalls are interconnected along axially extending edge portions with these edge portions also being relatively convergent at the outlet end and particularly at the point of fluid communication with the channel-shaped recess.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
174 words
A spray nozzle for producing a wide-angle, fan shaped fluid discharge pattern having a body with a longitudinal flow axis, a discharge end portion with an outer end face, and elongated clearance channel formed in said discharge end portion in transversely oriented relationship to said flow axis opening at said outer end face, and a spray pattern control chamber formed in said body along said flow axis and having an inlet end axially spaced from said discharge end portion and an outlet end disposed interiorally of said body and intersecting with said clearance channel thereby defining an outlet orifice, said control chamber being an elongated cavity of generally oval cross-section with a long axis thereof oriented perpendicular to said clearance channel and transversely to said flow axis, said chamber having axially extending sidewalls and edge portions interconnecting said sidewalls and which both converge throughout their length relatively inwardly toward each respective wall or edge portion in the direction of said outlet orifice said edge portions converging at a relatively greater rate than said sidewalls.
Claim 2
Dependent Claim
174 words
A spray nozzle for producing a wide-angle, fan shaped fluid discharge pattern having a body with a longitudinal flow axis, a discharge end portion with an outer end face, and elongated clearance channel formed in said discharge end portion in transversely oriented relationship to said flow axis opening at said outer end face, and a spray pattern control chamber formed in said body along said flow axis and having an inlet end axially spaced from said discharge end portion and an outlet end disposed interiorally of said body and intersecting with said clearance channel thereby defining an outlet orifice, said control chamber being an elongated cavity of generally oval cross-section with a long axis thereof oriented perpendicular to said clearance channel and transversely to said flow axis, said chamber having axially extending sidewalls and edge portions interconnecting said sidewalls and which both converge throughout their length relatively inwardly toward each respective wall or edge portion in the direction of said outlet orifice said edge portions converging at a relatively greater rate than said sidewalls.
Claim 3
Dependent Claim
29 words
A spray nozzle according to claim 1 wherein said sidewalls and interconnecting edge portions of said control chamber are arcuately curved in a plane transverse to the flow axis.
Claim 4
Dependent Claim
25 words
A spray nozzle according to claim 2 wherein said sidewalls and interconnecting edge portions are arcuately curved in a plane aligned with the flow axis.
Claim 5
Dependent Claim
36 words
A spray nozzle according 2 to claim 3 wherein said clearance 3 channel is of a V-shape with an apex thereof intersected by said spray control chamber at its outlet end to form said outlet orifice.
Claim 6
Dependent Claim
27 words
A spray nozzle according to claim 4 wherein said outlet orifice is of an elliptical configuration oriented with the long axis thereof aligned with said clearance channel.
Claim 7
Dependent Claim
34 words
A spray nozzle according to claim 1 wherein said clearance channel is of a V-shape with an apex thereof intersected by said spray control chamber at its outlet end to form said outlet orifice.
Claim 8
Dependent Claim
16 words
A spray nozzle according to claim 1 wherein said clearance channel is formed with planar surfaces.
Claim 9
Dependent Claim
28 words
A spray nozzle according to claim 1 wherein the portions of said sidewalls and interconnecting edge portions of said control chamber closely adjacent said outlet orifice are planar.
Claim 10
Dependent Claim
28 words
A spray nozzle according to claim 1 wherein said interconnecting edge portions of said spray control chamber are planar in a direction transverse to said sidewalls interconnected thereby.
Claim 11
Dependent Claim
30 words
A spray nozzle according to claim 9 wherein said clearance channel intersects said spray control chamber at a point to form an elongated outlet orifice aligned with said clearance channel.
Claim 12
Dependent Claim
17 words
A spray nozzle according to claim 1 wherein said clearance channel is formed with relatively divergent walls.
