1. A sprinkler comprising:

  • a nozzle;

    a spray range setting mechanism that is manually adjustable to set a desired elevation angle at which a stream of water exits from the nozzle;

    a flow control mechanism that is manually adjustable to vary the precipitation rate for the sprinkler; and

    a coupling mechanism between the spray range setting mechanism and the flow control mechanism which automatically adjusts the flow rate when the spray range setting mechanism is adjusted to maintain a substantially constant precipitation rate independent of changes in the spray range while permitting independent adjustment of the flow control mechanism without disturbing an existing spray range setting.
