ABSTRACT:
An ultrasonic vibrator which is preferable for transporting a small flow rate of powder is realized. A leaked vibrating energy is reduced to increase an efficiency of the device. A variation in performance influenced by the supporting process is eliminated to attain a stable performance. A vibrating amplitude at the horn part acting against the powder is increased. An AC voltage is applied to the piezo-electric elements through the electrodes. The vibrator may generate a complex vibration of the primary extending or retracting vibration and a secondary flex vibration, a lower end of the horn part is rotationally vibrated at an elliptical orbit indicated. The elliptical orbit has an elongated diameter extending in a lateral direction. The vibrator is made such that the inserting end of the shaft having the upper end flange part fixed thereto supports a section of the complex vibration of the vibrator. The powder fed from the resilient tube is promoted in a leftward direction as viewed in the figure under an elliptical motion of the bottom surface of the hole.
