POWDER PARTICLE DISTRIBUTION DEVICE AND SHIFTER

Title:

POWDER PARTICLE DISTRIBUTION DEVICE AND SHIFTER

Document Type and Number:

WIPO Patent Application WO/2003/031294

Kind Code:

A1

Abstract:

This powder particle distributing device (14) comprises a disk−shaped or conical distribution block (18), a distribution sleeve (22) coaxially disposed above the distribution block and cooperate with the distribution block to define a reservoir chamber (20) for powder particles, a feed sleeve (24) whose outer diameter is smaller than the inner diameter of the distribution sleeve, and that is disposed coaxial with the distribution sleeve to position its lower end within the distribution sleeve, and adapted to introduce the powder particles into the reservoir chamber, and an outer peripheral wall (26) formed with a plurality of discharge ports (32) for individually discharging the powder particles, which have passed through the distribution sleeve from the reservoir chamber, into the outside from distribution block, the outer peripheral wall (26) covering the outer periphery of the distribution block and distribution sleeve. A shifter (10) comprises the powder particle distribution device (14). As a result, the distribution device and the shifter are simple in construction and even when the mass velocity of the powder particles being fed at a high mass velocity varies greatly, particularly at a high mass velocity, it is possible to evenly and accurately distribute the powder particles.
