Patent ID: 7131600

Claim:
A reverse atomization chamber apparatus used for attachment to aircraft for the delivery of pesticides to a target area with the desire to reduce fines output during atomization, which apparatus comprises: a reverse venturi chamber open at each end, said chamber being divided into two sections, a left section and a right section, each section having two outer and inner segments, each of which segments has a top wall and bottom wall, the outer segments having the same radius concave radius upper wall and convex radius lower wall; while the inner segments have a same radius convex radius upper wall and a concave radius lower wall; a nozzle injector having a nozzle thereon disposed on one side in the inner segment, said injector being adapted for connection to a fluid source of pesticide, said nozzle being chosen such that exiting pesticide will not impact the walls of said chamber; and wherein the radii of the segments of the chamber are chosen such that the speed of atomization of the fluid pesticide by the incoming air is slowed down to reduce fines upon impact with the pesticide, and the speed of the pesticide air mixture on exiting the chamber is increased to substantially match the airspeed of the aircraft.
