Abstract:
1. A rotating stream sprinkler comprising: a deflector having an underside surface contoured to deliver a plurality of fluid streams generally radially outwardly therefrom through an arcuate span, the deflector defining a bore; and a nozzle body defining an inlet, an outlet, a central hub, and a valve sleeve, the inlet capable of receiving fluid from a source, the outlet capable of delivering fluid to the underside surface of the deflector, the central hub defining a bore and an internal helical surface; and the valve sleeve defining an external helical surface that adjustably engages the internal helical surface of the central hub to form an arcuate slot that is adjustable in size to determine the arcuate span; wherein the valve sleeve is rotatable through at least 180 degrees, rotation causing the external helical surface of the valve sleeve to traverse the internal helical surface of the central hub and adjust the size of the arcuate slot by at least 180 degrees; and wherein the valve sleeve is rotatable through substantially 360 degrees for adjustment of the size of the arcuate slot by substantially 360 degrees.
