Abstract
A multiple pre-orifice apparatus for a sprayer nozzle body with an upper end connected to a liquid source, a nozzle tip releasably mounted at a lower end thereof, and a channel between the upper and lower ends of the nozzle body. The apparatus comprises a sleeve assembly comprising a sleeve closed at an upper portion thereof by a top orifice plate defining a top orifice, and closed at a lower portion thereof by a bottom orifice plate defining a bottom orifice such that a sleeve turbulence chamber is formed between the top and bottom orifice plates. The sleeve assembly is secured in the channel such that a nozzle turbulence chamber is formed between the bottom orifice plate and the nozzle tip. The area of the flow opening in the nozzle tip is greater than the area of the top orifice which is greater than the area of the bottom orifice.
