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 cross-sectional 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.

A fluid-directing flow-amplifying nozzle comprising a rear body section and a forwardly-extending nozzle section; said body section including an axial portion, a cylindrical sleeve portion spaced radially from said axial portion, and an annular transverse wall portion extending therebetween; said axial, sleeve, and wall portions together defining a forwardly-facing annular recess; said nozzle section being threadedly and adjustably connected to said axial portion and having a rearwardly-projecting cylindrical collar received within said forwardly-facing recess; said collar being spaced radially from said axial portion to define an annular distribution chamber therebetween and being spaced radially from said sleeve portion to form an annular forwardly-extending flow-directing passage; and passage means provided by said body section for conducting a primary fluid under pressure into said distribution chamber; said collar having a rearwardly-facing annular surface movable in relation to said transverse wall portion of said body to define a selectively variable metering passage for altering the flow of primary fluid from said nozzle as the position of said threaded nozzle section is adjusted with respect to said body section.
