Title:
BLOW NOZZLE
Document Type and Number:
Japanese Patent JP3940380
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a blow nozzle capable of enlarging collision area of gas stream to be jetted and increasing the amount of gas stream to be jetted.
SOLUTION: Compressed air from a compressor is supplied to a supply part 2a of an injection nozzle 2, passes through a through hole 2c, and is jetted into a diffuser 3d of a cylindrical member 3 from a nozzle mouth 2d. Since air on a start end side and in a throat part 3c of the diffuser 3d is brought to a terminal side of the diffuser 3d by the injection, atmospheric pressure on the start end side and in the throat part 3c of the diffuser 3d is reduced, and outside air is sucked into a nozzle part 3b from introduction ports 4, 4, 4. Speed of outside air sucked from the introduction ports 4, 4, 4 is increased while it passes through the nozzle part 3b, and the outside air collides against high speed air stream jetted from the nozzle mouth 3d of the injection nozzle 2 and is mixed with the high speed air stream. Speed of the mixed jet stream which is collided and mixed air stream is decelerated and its pressure is increased while it passes through the diffuser 3d, and the mixed jet stream is jetted from a terminal of the diffuser 3d.
