Abstract
A spray tip configuration for a low pressure fluid sprayer is presented. The spray tip configuration comprises an inlet orifice configured to receive a fluid and to produce a turbulent flow at a known operating point. The spray tip configuration also comprises an outlet orifice configured to emit the fluid in a spray pattern at a turbulence intensity. The spray tip configuration also comprises a passageway fluidically coupling the inlet orifice to the outlet orifice, with a plurality of portions configured to produce the turbulence intensity at the outlet orifice. The passageway comprises a first portion comprising an expansion chamber configured to provide an expanding cross-section from a first portion first end to a first portion second end. The passageway also comprises a second portion comprising a first hydraulic diameter, wherein the second portion is fluidically coupled, on a second portion first end, to the first portion second end. The passageway also comprises a third portion comprising a second hydraulic diameter, wherein the third portion fluidically couples to the second portion at a third portion second end. The passageway also comprises a fourth portion comprising a…
