    FIELD OF THE INVENTION
    [001] The present invention relates in general to agricultural sprinklers and, more particularly, to a sprinkler nozzle apparatus for agricultural sprinklers. BACKGROUND OF THE INVENTION
    [002] In order to spray a fluid (eg, fertilizer, pesticide, fungicide, insecticide) on agricultural crops, agricultural sprinklers usually include a nozzle sprinkler device. The spray nozzle apparatus usually includes a nozzle connector to support a nozzle with a hole. The orifice geometry influences the flow, droplet size and spray pattern. The flow through the orifice is basically a function of the geometry of the orifice and the fluid pressure in the orifice (that is, pressure just before the orifice). Since the orifice geometry is typically fixed, the most common way to influence the flow through the nozzle is to change the fluid pressure. Changes in fluid pressure in the nozzle to influence flow changes have become commonplace in sprinklers to allow variable vehicle speed. The flow rate is changed in proportion to the vehicle speed in order to keep the application rate constant.
    [003] However, the use of a traditional fixed orifice nozzle has some limitations. The relationship of pressure to flow is a quadratic function. Doubling the flow requires a four-fold increase in pressure. Unfortunately, changing the pressure also changes the atomization dynamics, resulting in an impact on the spray quality. The quality characteristics of the spray, namely, droplet size and spray angle, both become smaller as the pressure increases. These changes can negatively impact the sprinkler deposit and sprinkler drag. Thus, the need arose for the ability to change nozzles in activity. SUMMARY OF THE INVENTION
    [004] In one embodiment, a spray nozzle device is revealed. The spray nozzle apparatus is adapted to receive fluid from a spray line of an agricultural sprinkler. The spray nozzle apparatus includes a housing for the apparatus. A control element is rotationally coupled to the device housing. A first nozzle connector with a first supply path and a second supply path is coupled to the device housing. A second nozzle connector with a third supply path and a fourth supply path is coupled to the device housing. The control element is configured to receive fluid from the spray line and selectively communicate fluid to at least one of the first supply path and the second supply path in a first position and to at least one of the third supply path and the fourth path supply in a second position.
    [005] In another embodiment, a spray nozzle device is revealed. The spray nozzle apparatus is adapted to receive fluid from a spray line of an agricultural sprinkler.

Referring to figure 21, the spray nozzle cartridge 850 includes slots 852 to releasably fit protrusions 832.
    [0063] With additional reference to figure 20, exemplarily, the spray nozzle cartridges 850 include a cylindrical cartridge housing 855 with a general convex surface 857. A first tip of the nozzle 860 with a first flow path 865, a second tip of nozzle 875 with a second flow path 880 and a third tip of nozzle 890 with a third flow path 895 are coupled to the cartridge housing in a cylindrical shape 855 in a linear pattern. This disclosure contemplates that the tips of the nozzles 860, 875, 890 can be coupled to the cartridge housing in a cylindrical shape 855 in any pattern (for example, non-linear, circular, square). This disclosure also contemplates that the nozzle connectors 830, 830 ', 830 ", 830"' (figure 19) and the cylindrical cartridge housing 855 can be of any shape (for example, square, rectangular, oblong).
    [0064] Although the disclosure has been illustrated and described in detail in the drawings and in the description presented, such illustration and description must be considered of an exemplary character, and not restrictive, it should be understood that illustrative modalities were shown and described and that all changes and modifications that fit the spirit of the disclosure must be protected. It is noted that alternative modalities of the present disclosure may not include all of the features described and still benefit from at least some of the advantages of such features. Those skilled in the art can easily design their own implementations which incorporate one or more of the features of the present disclosure and which fall within the spirit and scope of the present invention defined by the appended claims.
