Impulse sprinkler deflector spoon |
摘要 |
A deflector spoon for a rotary impulse sprinkler includes upper and lower relatively sharply curved deflector faces separated by an intermediate, relatively gradually ramped deflector face. The three deflector faces are designed to react with a water stream from a sprinkler nozzle with the same driving force regardless of the specific water stream trajectory.
