Irrigation nozzles
View Patent ↗An irrigation nozzle is provided. The irrigation nozzle comprises a nozzle body forming a first body portion. The first body portion is generally cylindrical in shape and forms a nozzle cavity and at least one deflecting nozzle passage. Each deflecting nozzle passage extends from the nozzle cavity to an exterior surface of the first body portion. Each deflecting nozzle passage includes a deflector surface located adjacent to an exterior surface of the first body portion. The size and spatial orientation of each deflector surface and the curvature and hydraulic diameter of each deflecting nozzle passage upstream from each deflector surface are configured such that water flowing from the nozzle cavity through each deflecting nozzle passage impinges upon each deflector surface and spreads tangentially to a desired magnitude while flowing radially outward from said first body portion on a desired trajectory. The nozzle body is constructed as a unitary object.
