Abstract

In low drift spray nozzles and a method of applying low drift sprays, liquid is formed in large droplets by imparting a swirling motion to the liquid in a chamber of the nozzle, passing the swirling liquid through a first orifice into another chamber of the nozzle which is larger in cross section than the orifice, and discharging the swirling liquid from the last mentioned chamber through a second orifice which is at least as large in cross section as the first orifice, whereby the discharged liquid forms a hollow geometric shape having large droplets of the liquid therein.
