Abstract (en)
[origin: US5052622A] In a sprinkler (1), the water distributors (10) for supplying the spray nozzles (13, 14, 15) is formed by a separate main channel (15) inserted in a spray nozzle casing (2) and having relatively small flow cross-sections compared with the casing cross-sections, which is also constructed in one piece with the spray nozzles (13, 14, 15), so that the spray nozzle casing (2) does not have to be used for water distribution purposes and can instead merely serve as a support casing. Of the spray nozzles arranged in a row, those which are located at the end of the row can be individually manually disconnected with separate check valves (36), so that in simple manner it is possible to adjust the width of the exiting water curtain within certain limits.
