Abstract
A variable arc spray nozzle is provided for delivering irrigation water to a surrounding terrain area in a spray pattern of variably adjustable arcuate width. The spray nozzle is adapted for mounting onto the upper end of a water supply riser, and includes a rotatable adjustment collar which cooperates with an upper deflector to define a discharge orifice of variably selected arcuate width. A stabilizer vane on the adjustment collar protrudes generally upstream at the adjustable side edge of the discharge orifice to tailor the associated side edge of the resultant spray pattern for improved water distribution and range. The deflector additionally includes a substantially horizontal step formed at the upstream side of the discharge orifice to produce a localized pressure loss resulting in improved water distribution across the variable width of the spray pattern. This horizontal step leads to a radially outwardly inclined deflector surface which is interrupted by a substantially vertical step at the downstream side of the discharge orifice for increasing the trajectory and range of throw for the discharged water stream.
