Abstract:
A sprinkler spray head adapted to be coupled to a supply of water under pressure, comprising:a generally cylindrical body having a first end adapted to be coupled to a supply of water under pressure, and defining at least one spray nozzle for projecting water outwardly therefrom in a selected spray pattern, and at least one internal flow path for flow of water under pressure from said first end to said spray nozzle;said internal flow path being defined by a relatively narrow metering orifice for flow of water from said first end, and an elongated open-sided flow channel extending from said metering orifice to said spray nozzle;said body further defining a plenum chamber of relatively large cross sectional area and a length substantially greater than said metering orifice, said elongated open-sided flow channel extending vertically through said plenum chamber in flow communication therewith.
