Nodalized nozzle for injecting powder, particularly in powder metallurgy, comprises central body that projects dust of feeding tube settled on body, where moving crown is adjusted and positioned with respect to body

摘要

The nozzle comprises a central body that projects dust, through an axial hole, of a feeding tube settled on the body. A moving crown is adjusted and positioned with respect to the body for supplying gas confinement fed through lateral tubes. The tubes flow into a chamber defined between the central body, the moving crown and an intermediate body for fixing the latter. A coupler, transparent to the laser beam, is set axial to the central body. A laser generator is positioned by micrometric screws.
