Abstract
A self-cleaning sprinkler is disclosed. The self-cleaning sprinkler includes a housing having an internal chamber. The internal chamber defines an interior scraping surface. A rotatable spool is disposed within the internal chamber. The spool includes external threads, defining a spiral passageway. Pressurized fluid passing through the spiral passageway causes the spool to rotate. As the spool rotates, debris is compressed between the threads and the scraping surface, breaking the debris up into smaller pieces.
Claims20
A self-cleaning sprinkler for connection to a source that conveys pressurized fluid to the sprinkler, comprising:
- a housing having an internal chamber and an interior scraping surface;
- and
- a rotatable spool disposed within the internal chamber, the spool comprising external threads defining a spiral passageway proximate the scraping surface of the housing, wherein the pressurized fluid traveling through the spiral passageway causes the spool to rotate causing debris to scrape the scraping surface and to be broken into smaller pieces.
A self-cleaning sprinkler in fluid communication with a source that conveys pressurized fluid to the sprinkler, comprising:
- a housing having an internal chamber defined by at least:
- a first barrier region;
- a second barrier region;
- and,
- an interior scraping surface interposed between the first and the second barrier regions;
- and
- a rotatable spool disposed within the internal chamber, the spool comprising external threads defining a spiral passageway proximate the scraping surface of the housing and an angled exit channel in fluid communication with the passageway, wherein the pressurized fluid traveling through the spiral passageway and angled exit channel causes the spool to rotate causing debris to scrape the scraping surface and to be broken into smaller pieces.
