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.
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.
