Abstract
The valve, according to the illustrated embodiment, comprises an annular chamber formed of concentric inner and outer walls, the outer wall having, in the periphery thereof, a multiplicity of equally spaced apart rectangular slots. An annulus, having a corresponding multiplicity of slots, is rotatably journalled, concentrically, on the outer periphery of the outer wall in order that, upon rotation thereof, relative to the annular chamber, the slots in the wall, and those in the annulus, come into or out of registry. A crank mechanism is coupled between the annulus, and the structure defining the annular chamber, to selectively rotate the annulus through a limited arc to bring the slots into and out of such registry. The valve is used to throttle the velocity of compressed gas product conducted thereto by a gas compressor, and to subdivide compressed gas issuing therefrom into a multiplicity of fine jets.
