Abstract
A pop-up irrigation sprinkler which includes a riser which is forced by water pressure up out of a body through a cover attached to the top of the body. The riser is normally held in a retracted position by a coil spring. A nozzle is removably attached to the upper end of the riser. An adjustable screw is threaded into the nozzle to adjust the flow rate of water through the nozzle to control both the flow rate and the radius of the watering pattern. An elongated filter is removably mounted on the inner end of the nozzle, and the filter extends down into the riser. The filter has a head having an orifice therein and which defines a conical seat for the screw. An adapter is interposed between the nozzle and the riser and serves to trap the head of the filter to enable different types of nozzles from different manufacturers to be used in the sprinkler.
