Abstract
A round or annular jet nozzle for the production and discharge of a mist or aerosol for coating objects, including a nozzle cap forming the axial front end of the nozzle, a nozzle body mounting the cap, which nozzle body has two channels for feeding of flowable coating material such as lacquer or paint powder, and respectively, for feeding of an atomization gas standing under pressure such as pressurized air, the two channels extending at least partly parallel to the nozzle axis, an annular-shaped atomization chamber into which the two feed channels exit approximately parallel, and with a conical annular gap for the exit of the mist and aerosol, respectively, the annular gap diverging forwardly with respect to the nozzle axis, the annular gap standing in connection with the atomization chamber. The atomization chamber and the annular gap pass directly into each other, the opening angle of the conical mouth of the annular-shaped material feed channel corresponds at least approximately to the opening angle of the annular gap, and the mouth is aligned with the annular gap. A second channel is provided for feeding of the atomization gas standing under pressure and the two annular-shape…
