GORGE SECTION VARIABLE FLUID NOZZLE

摘要

PROBLEM TO BE SOLVED: To provide a fluid nozzle in which the sectional area of a gorge is variable. SOLUTION: The gorge section variable fluid nozzle is characterized in that the sectional area of the gorge can be changed by shifting both ends of a cylindrical sidewall composed of an elastic material along the circumference relative to each other. Also, the gorge section variable fluid nozzle is characterized in that the cylindrical sidewall is formed by embedding a core material made of a metal material or the like in a long and narrow member made of a polymer or the like. Also, the gorge section variable fluid nozzle is characterized in that the cylindrical sidewall composed of an elastic material is inserted inside the cylinder.
