Abstract

An improved spray nozzle for use with aircraft includes a small diameter, plastic body having a forward liquid inlet and a transverse cavity receiving liquid chemicals under pressure through the inlet. A plurality of capillary tubes in fluid communication with the cavity are secured in the body to open rearwardly in a horizontal, planar fan-shaped configuration protruding from a rear wedge shaped end of the body. The transverse distance across the body and the capillary tubes is less than one and one-half inches to minimize gravity pressure differentials across the plurality of tubes when the aircraft is banked to thereby prevent liquid chemical dribbling. A removable baffle is secured within the transverse cavity in position to be impinged by the entering liquid chemicals to equalize liquid flow and pressure throughout the cavity to thereby provide equal flow through each of the capillary tubes.
