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 frusto-conical plug having an upper chamber and a lower portion provided with four specified longitudinally-extending passages surrounding a central core, each passage leading to an associated individual, unconnected, peripheral, longitudinally-extending passage of a four passage cylindrical conduit. Ports are arranged around the conical face of the frusto-conical plug and at at least two locations along its axial length, to communicate with the four specified passages passages. An apertured frusto-conical sleeve, is rotatably movably connected and is disposed about the frusto-conical valve plug, by means of a shaft disposed within the central, hollow core. The frusto-conical sleeve has a plurality of ports arranged around its conical face in an orientation identical to that of the ports in the frusto-conical plug and at at least one location along its axial length in an orientation similar to that of the ports of said frusto-conical plug, 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 conduct, and the downstream side thereof is connected to a water spray. Upon rotation of the the frusto-conical sleeve, the shape of the spray pattern and/or the size of the spray area, 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 frusto-conical valve plug having a upper chamber and a lower portion provided with four individual, unconnected, peripheral, longitudinally-extending passages surrounding a central, hollow core, each passage leading to an associated individual, unconnected, peripheral, longitudinally-extending passage of a four passage cylindrical conduit; a plurality of ports arranged around the conical face of said frusto-conical plug and at least two locations along its axial length, each said port communicating with an associated one of said four individual, unconnected, peripheral, longitudinally-extending passages; a frusto-conical sleeve disposed about said frusto-conical valve plug and rotatably movably mounted with respect thereto by means of a shaft disposed within said central, hollow core, said frusto-conical sleeve having a plurality of ports arranged around the conical face of said frusto-conical sleeve in an orientation identical to that of said ports in said frusto-conical plug and at at least one location along its axial length in an orientation similar to that of the ports of said frusto-conical valve plug, the leading edges of said ports therein being adapted to index precisely with the leading edges of selected ports of said frusto-conical valve plug; means for indirectly connecting the upstream side of said intake nozzle and valve structure to a water-conducting conduit; and means for connecting the downstream side of each of said four longitudinally-extending passages of said intake nozzle and valve structure to an associated quadrant of a four quadrant water deflection head; whereby upon rotation of said frusto-conical sleeve with respect to said frusto-conical valve plug, the shape and size of the spray area may be controlled at will to a full square spray pattern, a one-quarter square spray pattern, a one-half square spray pattern or a three-quarter square spray pattern through cooperation between said ports in said frusto-conical valve plug with said ports in said frusto-conical sleeve.
