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.

A nozzle for producing a swirling discharge of a hollow geometric shape having substantially large droplets therein, said nozzle comprising a first chamber having a fluid inlet for introducing fluid to said first chamber, swirl means for imparting a swirling motion to the fluid in said first chamber

A nozzle for producing a swirling discharge of a hollow geometric shape having substantially large droplets therein, said nozzle comprising a first chamber having a fluid inlet for introducing fluid to said first chamber, swirl means for imparting a swirling motion to the fluid in said first chamber, a second chamber, first orifice means between said first and second chambers, said swirling fluid passing from said first chamber to said second chamber through said first orifice means, said second chamber being larger in cross section than said first orifice means, and means for discharging the swirling fluid from said second chamber while still in its swirling condition to form said swirling discharge of said hollow geometric shape and having said substantially large liquid droplets therein, said means for discharging includng second orifice means at an end of said second chamber opposite said first orifice means, said second orifice means being at least as large in cross section as said first orifice means.
