Abstract:
A variable arc spray nozzle, comprising:a tubular nozzle body adapted for coupling to a supply of water under pressure;first and second nozzle members carried by said nozzle body and cooperatively defining opposite side edges of a discharge orifice for radially outward projection of water from the spray nozzle, said first nozzle member being movable with respect to said second nozzle member for defining a movable side edge of said discharge orifice whereby the arcuate width of said discharge orifice and a resultant spray pattern of water projected therefrom can be variably adjusted;said first nozzle member including a stabilizer vane projecting upstream from said discharge orifice at said movable side edge thereof for tailoring the water distribution and range of throw of the resultant spray pattern at one side edge thereof; andone of said first and second nozzle members comprising a deflector defining a substantially horizontal annular inner step disposed at an upstream side of said discharge orifice, an inner deflector segment extending radially outwardly from said inner step with a selected inclination angle, said inner deflector segment merging with a substantially vertical annular outer step disposed at a downstream side of said discharge orifice, and an outer deflector segment extending radially outwardly from said outer step with a selected inclination angle.
