Abstract: The powder dispersion device has a chamber (10) housing a block (12) of compacted powder, with a piston (14) exercising pressure on the block. A pressurized gas stream is directed onto the block on the side opposite the piston. The gas gathers powder and is directed through a passage (18) past a tapered needle (40) that controls the flow and deflects the stream to outlet passages (22).
