摘要： An improved sprinkler head for an irrigation system wherein the sprinkler heads are designed to include spray means for adequately watering both the area within two feet, the "dead zone", of each spray head and areas beyond two feet. The sprinkler head employs a high velocity primary outlet and a secondary low velocity spray outlet for covering the "dead zone". A tortuous pathway is formed between the primary passageway and second low velocity outlet which functions to induce turbulence substantially reducing pressure and velocity of the spray therefrom.
