A novel four passage intake nozzle and valve structure is provided for use with a specially designed, novel water deflection member to provide a pop-up water spray nozzle. The novel intake nozzle and valve structure includes a hollow valve plug, having a lower cylindrical portion provided with four specified longitudinally-extending passages, and an upper cylindrical portion provided with four specified, longitudinally-extending passages the upper and lower passages surrounding a central core. The upper passages are connected to associated lower passages through an associated, smaller diameter aperture. Parts in the valve plug, communicate with an associated one of the four lower passages. An apertured disc, is rotatably movably connected to the valve plug, by means of a shaft disposed within the central, hollow core, the apertured disc having ports therein, the leading edges of the ports therein being adapted to index precisely with the leading edges of selected ports of the valve plug. The upstream side thereof is connected to a water-conducting conduit, and the downstream side thereof is connected to a water spray structure. Upon rotation of the apertured disc the size of the spray area, or full square pattern may be selected and controlled at will.

An intake nozzle and valve structure for use with a water deflection member, said intake nozzle and valve structure comprising: a hollow valve plug having a lower cylindrical portion provided with four lower individual, unconnected, peripheral, longitudinally-extending passages surrounding a central hollow core thereof, and an upper cylindrical portion provided with four upper individual, unconnected, peripheral, longitudinally-extending passages surrounding said central hollow core, an associated one of said upper passages being connected to an associated one of said lower passages through an associated smaller diameter aperture; a plurality of ports in said valve plug, each port selectively communicating with an associated one of said four individual, unconnected, peripheral, longitudinally-extending lower passages; an apertured disc rotatably movably mounted with respect to said valve plug and connected to said valve plug by means of a shaft disposed within said central hollow core, said apertured disc having a plurality of spaced-apart ports therein, the leading edges of a selected plurality of said ports therein being adapted to index precisely with the leading edges of a selected plurality of ports in said valve plug; means for connecting the upstream side of said intake nozzle and valve structure to a water-conducting conduit; and means for connecting the downstream side of said four, longitudinally-extending passages of said intake nozzle and valve structure to an associated quadrant of a four quadrant water deflection member; whereby upon rotation of said apertured member with respect to said valve plug, the size of a selected full square spray pattern, a selected one-quarter square spray pattern, a selected one-half square spray pattern or a selected three-quarter square spray pattern may be controlled at will through cooperation between a plurality of said ports in said valve plug with a plurality of said ports in said apertured disc.
