<p>PROBLEM TO BE SOLVED: To provide a spray nozzle capable of achieving both acceleration of atomization of a spray fluid and either reduction in an amount of a used spray medium for use to atomize the spray fluid or reduction in pressure force.SOLUTION: A spray nozzle is configured so that a mixing chamber is provided on a spray-nozzle tip end portion, communicates a spray fluid channel with a spray medium channel, and mixing up a spray fluid flowing in the spray fluid channel and a spray medium flowing in the spray medium channel into a mixture fluid; a branch portion is formed for branching off the mixture fluid mixed in the mixing chamber to a plurality of mixture fluids flowing in a plurality of mixture fluid channels, the mixture fluid channels in which the branched-off mixture fluids flow are provided, the mixture fluid channels near the spray-nozzle tip end portion are arranged so as to form merger portions in each of which the mixture fluids flow as countercurrents and are merged together, and outlet holes communicating with the respective merger portions are provided on the spray-nozzle tip end portions for spraying the mixture fluid mixed up in each of the merger portions to an outside from the spray nozzle.</p> |
