Abstract (en)

An ultra-fine spray-jetting nozzle includes a liquid passage (37) and a gas passage (41) that is disposed on a peripheral side of the liquid passage (37) through a partitioning wall and communicates with a jetting port (A). An outer surface of the partitioning wall at a jetting port side thereof is formed sectionally polygonal, long circular or elliptic. A peripheral surface of the gas passage (41) is formed sectionally circular. The outer surface of the partitioning wall having the configuration is brought into contact with the sectionally circular peripheral surface of the gas passage (41) at a plurality of positions to circumferentially divide the gas passage (41) at the jetting side into a plurality of gas passages. A gas jetted from jetting ports (A) of a plurality of the separate gas passages is mixed with a periphery of a liquid jetted from the liquid passage (37) to generate spray.
