Abstract
A static, sector-type water sprinkler producing a variable-sector water-distribution pattern includes an outlet opening in the form of a helical slot having an effective length around the circumference of its housing which may be varied for preselecting the sector angle of the water distribution around the sprinkler, and a blocking member engageable with the inner surface of the housing on opposite sides of the slot to preselect the portion thereof to be unblocked and thereby the sector angle of the water distribution around the sprinkler.
