Title:
PULSE AIR JET NOZZLE
Document Type and Number:
Japanese Patent JP3909418
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a mobile pulse jet nozzle comprising a blowing nozzle capable of moving and changing the direction of a pulse air stream.
SOLUTION: A pulse air blowing port is provided in a spherical nozzle case in which a pivoted rotary blade is incorporated. A couple of an upper part air stream suction port and a lower part air stream suction port is provided at a position opposed to the pulse air blowing port of the nozzle case so that compressed air sucked from the respective suction ports blows against the upper and lower and left and right both edges of the rotary blade. When the compressed air blows against the edge parts of the rotary blade, reverse moment is produced and the rotary blade is rotated in one direction by the difference of both moments to make the pulse stream produced by the rotation flow out from the pulse air blowing port.
