ABSTRACT:
Efficient and silent air nozzle assembly for discharging a small amount of compressed gas, such as air, to entrain a larger amount of secondary air and direct or focus the composite air mixture against a work station, such as for cleaning or ejection purposes. The air nozzle comprises a conduit having an exit orifice into which is pressed a solid nozzle plug having a multiplicity of peripheral longitudinal surface recesses which provide a multiplicity of small gas passages between the plug and the inner surface of the conduit. The plug has an inwardly tapered tip which extends out of the exit orifice of the conduit to cause the exiting gas to entrain surrounding or secondary air and direct the gas-air mixture along the tapered surface thereof where it converges as a concentrated air flow.
