ABSTRACT:
A flow-amplifying nozzle having a construction which facilitates production, reduces costs, and enhances the safety of such a nozzle in operation. Such construction is particularly suitable for relatively small-size nozzles designed to direct and amplify the flow of compressed air or other pressurized fluid. The nozzle is composed of two pieces, one being a rigid tube having a closed, tapered nose portion and a plurality of radial openings in the cylindrical portion immediately adjacent the nose, and the other being a collar extending about and secured to the tube's cylindrical portion. The collar redirects the flow of fluid discharged through the radial openings, causing it to be expelled forwardly over the tapered nose of the nozzle. Secondary air is entrained by the rapid flow of primary air and thereby amplifies the total flow of air directed by the nozzle.
