ABSTRACT:
A pressure-regulated water sprinkler comprises a sprinkler head carrying a nozzle at one end through which the water discharges in the form of a jet. The sprinkler head includes a housing defining an internal chamber communicating at one end with the nozzle and having an inlet at another end. The nozzle end of the housing is formed with a plurality of internal ribs spaced circumferentially and extending longitudinally to a point within the chamber intermediate the nozzle and inlet ends. The ribs are formed with a first annular shoulder adjacent to the nozzle end of the chamber, and with a second annular shoulder more remote from the nozzle end and of larger diameter than the first annular shoulder. An annular ring within the chamber has one side bearing against the second annular shoulder and its opposite side facing the housing inlet. A regulator member is movable between the ring and the first annular shoulder; and a pressure sensor is provided for sensing the inlet pressure and automatically moving the regulator member towards and away from the annular ring to regulate the flow therethrough to the nozzle.
