Abstract: A sprinkler system for distributing water from a source substantially evenly over an area of terrain comprises a body defining a passage having an inlet connected to an outlet extending at an angle to the inlet, and a generally circular nozzle plate having a plurality of nozzles therein rotatably mounted at the outlet for selectively positioning a selected one of the plurality of nozzles in alignment with the outlet for distributing a stream of water outward from the housing, and the nozzle plate being selectively rotatable for selectively moving the nozzle plate to a selected nozzle position.

Abstract: A sprinkler nozzle for distributing water from a source over an area of terrain comprising a body defining a passage having an inlet section connected by a curve to an outlet section extending at an angle to the inlet section, and a vent port in the passageway at the inside of the curve communicating with an annular chamber surrounding the inlet section for enhancing the reach of the nozzle.
