Stacked pre-orifices for sprayer nozzles

A multiple pre-orifice spraying apparatus for spraying an agricultural chemical, the apparatus comprising:

• a sprayer nozzle body comprising a first end connected to a liquid source to receive liquid to be sprayed, a nozzle tip releasably mounted at a second end thereof, and a channel between the first and second ends of the sprayer nozzle body, the sprayer nozzle body including a continuous sidewall lacking any aperture;
• a sleeve assembly comprising a sleeve including a substantially flat first orifice plate defining a first orifice, and spaced apart from a substantially flat second orifice plate defining a second orifice such that a sleeve turbulence chamber with substantially straight parallel walls is formed between the first and second orifice plates;
• wherein the sleeve assembly is configured to be secured in the channel such that, when secured, a nozzle turbulence chamber with substantially straight parallel walls is formed between the first orifice plate and the nozzle tip and the first orifice plate and the second orifice plate are substantially perpendicular to the straight parallel walls;
• wherein an area of the first orifice is greater than an area of the second orifice, and an area of a flow opening in the nozzle tip is greater than the area of the first orifice;
• wherein the first orifice, the second orifice, and the flow opening in the nozzle tip are aligned;
• wherein the first and second orifice plates are located in a lower portion of the sleeve;
• and
• whereby the nozzle body and sleeve assembly are capable of causing droplets of the liquid exiting the flow opening in the nozzle tip with the sleeve assembly in place to have an increased droplet size compared to droplets of the liquid exiting the flow opening in the nozzle tip when the sleeve assembly is removed.
