<p>FLOW AMPLIFYING NOZZLE An adjustable nozzle for directing and amplifying the flow of compressed air or other pressurized fluid. The nozzle includes a rear body section and a front nozzle section, the two sections being threadedly connected to define a forwardly-facing flow-directing passage and a radially-extending metering passage communicating with the flow-directing passage. The size of the metering passage may be selectively adjusted without altering the crosssectional dimensions of the flow-directing passage by rotating the nozzle section into any selected position of threaded adjustment upon the body section, such position(and the relative dimension of the metering section) being indicated by micrometer markings upon the exposed surfaces of the respective sections.</p> |
