Abstract
A static, sector-type water sprinkler producing a variable-sector water-distribution pattern, includes an outlet opening having an effective length around the circumference of its housing which may be manually varied for preselecting the sector angle of the water distribution around the sprinkler. The outlet opening is defined by a helical slot, and its effective lenth is varied by a blocking member which is manually movable with respect to the slot to preselect the portion thereof to be unblocked, and thereby the sector angle of the water to be distributed around the sprinkler.
