  • Patent number: 5687906
    Abstract: An atomizing method for atomizing a fluid atomizing material feeds fluid atomizing material into jet air. A pair of planar air jets flow through nozzle tips towards a center axis of an atomization material supply. This forms an air chamber which converges in front of the atomization material supply. The interior edge of the converged air jets has a zone of slow moving air that draws the fluid atomizing material into the converging air jets. The material is thus atomized and evenly distributed. The atomization material supplied includes such fluidized atomizing materials as molten metal droplets fused by arc heat, paints, blast materials, adhesives, powders, etc.

  • Patent number: 5584433
    Abstract: The present invention is directed to an atomizing method for atomizing a fluid atomizing material. The method includes feeding the fluid atomizing material into jet air. According to a feature of the instant invention, there is provided a method which includes jetting a pair of planar jet air flows through nozzle tips towards a center axis of an atomization material supply means, forming an air chamber which converges at a forward end, followed by supplying the, thus formed, air chamber with the fluid atomizing material in a non-atomizing form. The atomization material supply means includes fluid atomizing material such as molten metal droplet fused by arc heat, paint, blast material, adhesive, powder, etc.
