A multiple pattern spray nozzle is provided for connection to a supply of water under pressure, wherein the spray nozzle is adjustable upon movement of a single selector ring to one of several different spray pattern settings. The spray nozzle comprises a nozzle housing for mounting, for example, onto a hose end trigger valve or the like and supporting a stem unit for receiving the supply of water under pressure. A pair of flow control sleeves are carried by a perforate faceplate for sliding movement relative to the stem unit and nozzle housing to define different water flow paths leading respectively from the stem unit to different nozzle outlets formed by the faceplate in cooperation with the stem unit and nozzle housing. The selector ring in turn supports the faceplate and flow control sleeves and is threaded onto the nozzle housing for rotation thereabout to displace the flow control sleeves to select the water flow path and associated nozzle outlet open to water flow, thereby selecting the spray pattern setting. In the preferred form, the selector ring is rotatable to any one of five different setting positions to provide a discharged water stream in the form of a low flow mist, a conical spray, a narrow collimated jet spray, a gentle shower spray, or a generous low-force soaker flow.
