ABSTRACT:
An irrigation sprinkler nozzle for use in a rotary sprinkler for projecting the entire fluid stream between about 15 and about 35 feet from the rotary sprinkler regardless of the upstream pressure. The irrigation sprinkler nozzle comprises a nozzle body having a longitudinal axis, a side wall, and an exit wall. Coupled to the nozzle body is a restrictor plate that is spaced from the exit wall. Defined by the side wall, the exit wall, and the restrictor plate is a fluid chamber. The nozzle includes an inlet to the chamber defined by the restrictor plate. Preferably, the inlet has a cross-sectional area so that a pressure inside the chamber is less than a pressure upstream of the inlet. The nozzle also has an outlet from the chamber defined by the exit wall for projecting a fluid stream outwardly from the irrigation sprinkler nozzle. The chamber may be configured to form a turbulent flow within the chamber.
