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.
Claims19
A static, sector-type water sprinkler producing a variable-sector water-distribution pattern, including a housing formed with an inlet opening at one end connectible to a supply of pressurized water, and an outlet opening having an effective length around the circumference of the housing which may be varied for preselecting the sector angle of the water distribution around the sprinkler;
- characterized in that said outlet opening is defined by a slot extending helically around substantially the complete circumference of the housing;
- and
- in that said sprinkler further includes a blocking member movable with respect to said slot to preselect the portion thereof to be unblocked by said blocking member, and thereby the sector angle of the water distribution around the sprinkler.
A static, sector-type water sprinkler producing a variable-sector water-distribution pattern, comprising:
- a housing formed with an inlet opening at one end connectible to a supply of pressurized water, and an outlet opening having an effective length around the circumference of the housing which may be manually varied for preselecting the sector angle of the water distribution around the sprinkler;
- said outlet opening being defined by a slot of fixed length extending helically around substantially the complete circumference of the housing;
- said sprinkler further including a blocking member manually movable with respect to said slot to preselect the portion thereof to be unblocked by said blocking member, and thereby the sector angle of the water distribution around the sprinkler.
