A cap is disposed internally of a spray nozzle and effects active atomization of pressurized liquid flowing through the nozzle by mixing with compressed air and creating turbulence in the liquid during the flow. The nozzle includes an internal cap which cap which imparts significant turbulence on the flow through the nozzle serving to help atomize the liquid using a reduced amount of air energy. Different caps may be used to create various selected spray patterns.

[ I claim:] [1.] A nozzle for atomizing and spraying pressurized liquid into the atmosphere comprising a body having an annular side wall, an open upstream end and a downstream end, a discharge opening in the downstream end of said body, an atomizing cap disposed in said body and having an inlet located adjacent the upstream end of said body, said cap having an annular side wall spaced radially inwardly from the side wall of said body for defining an annular chamber between said side walls, said cap having an axially facing intermediate wall perpendicular to said side wall and spaced downstream of said inlet and upstream of said discharge opening for defining a cylindrical chamber on a downstream side of said intermediate wall, said discharge opening being sized sufficiently large in relation to the diameter of said cylindrical chamber that pre-atomized liquid in said cylindrical chamber may proceed through said discharge opening with substantial radial restriction, a first set of circumferentially spaced passages formed through the side wall of said cap upstream of said intermediate wall for conducting liquid from said inlet to said annular chamber, a second set of circumferentially spaced passages formed through said side wall of said cap downstream of said intermediate wall for conducting liquid from said annular chamber to said cylindrical chamber and discharge opening, said second set of passages including at least five equally spaced passages extending tangentially of said cap whereby liquid is caused to flow outwardly as circumferentially spaced jets from said inlet to said chamber, to flow axially downstream of said annular chamber, and then to flow inwardly as circumferentially spaced jets from said annular chamber to said cylindrical chamber and discharge opening for producing a wide angle spray pattern.
