ABSTRACT:
A fixed spray sprinkler nozzle has adjustable arc coverage. The nozzle has a nozzle body with sideward facing water discharge slots including a bottom slot and a top slot. Flow blocking skirts control the open length of each of the slots. The bottom slot is fixed on the nozzle body, but the top slot is rotatable on the nozzle body, in concert with the opening or unblocking of the bottom slot's length, from a position overlying the bottom slot to a position directed in an opposite direction from the bottom slot. When the bottom slot is fully open, the top slot may then be progressively opened over its entire length. Thus, the arc coverage can be infinitely adjusted over the combined circumferential length of both the bottom and top slots together. The slots have a grooved bottom wall to provide smooth water flow and good pattern definition at each side of the selected arc.
