ABSTRACT:
A one-piece spray nozzle for the metered mixing and dispensing of a carried fluid with a primary carrier fluid comprising a first connection for connecting the nozzle to a source of the carried fluid and a second connection adapted for carrying the nozzle to a source of the primary carrier fluid. A jet passageway communicating with the second connection projects the primary carrier fluid in a stream. A mixing chamber is aligned with the jet passasgeway but is separated from the jet passageway by an air gap or recess. A passage extending between the first connection and the mixing chamber conducts the carried fluid under gravity to the mixing chamber. The mixing chamber is sized so that the stream of the primary carrier fluid does not contact the walls of the mixing chamber but draws a stream of a secondary carrier fluid from the air gap or recess through the mixing chamber. The stream of the secondary carrier fluid draws the carried fluid into the chamber to mix with the primary carrier fluid.
