Irrigation sprinkler nozzle with enhanced close-in water distribution |
摘要 |
An improved irrigation sprinkler nozzle is provided for enhanced short range or close-in distribution of water for irrigating vegetation and the like positioned relatively close to the sprinkler. The improved sprinkler nozzle includes a nozzle passage for outward projection of a water stream, at least a portion of which is defined by a generally vertically oriented, fan-shaped spray pattern. A lower margin of the nozzle passage defining this fan-shaped pattern is lined with a plurality of forwardly extending ramps each formed with a selected width and a different declination angle. A portion of the water discharged through the nozzle passage is forced and guided downwardly along these ramps for enhanced close-in distribution of water near the sprinkler.
