ABSTRACT:
A spray nozzle having a brass housing and a urethane insert that is relatively resistant to wear by contact with the flow of irrigation water. The insert protects the more costly housing from erosion and is easily replaced if it becomes worn or if it is necessary to change the spray pattern. The housing can form a sleeve in which the insert is slidably received so that the housing is completely insulated from contact with the water flow. In one embodiment, the insert forms a concave deflector having ridges on a surface impinged by the water so that the spray emitted consists of discrete streams for greater distance and wind resistance. The water is emitted toward the deflector through an oblong orifice for more uniform lateral water distribution.
