Abstract: An improved irrigation device is provided for precision, relatively low energy and close range delivery of irrigation water to crops and the like with little or no soil erosion. The irrigation device comprises a generally cylindrical body for connection to the lower end of a vertical drop tube adapted for connection in turn to a water supply pipe, for example, of a traveling irrigation system, such as a center pivot or linear system. The cylindrical body carries a downwardly open nozzle for discharge of water into a pressure-regulated chamber defined in part by a funnel-shaped regulator cover slidable about the cylindrical body. The chamber is shaped or otherwise includes means for dissipating a substantial portion of the flow energy of the water discharged into the chamber.
