A vortex tube assembly equipped with a control mechanism for use in selectively adjusting the temperature of air discharged from the primary outlet of the assembly to any temperature within the range from maximum hot to maximum cold, the temperature of the discharged air varying in generally linear relation with adjustments in the position of a temperature control handle. Ideally, the temperature of the discharged air may thus be varied without significantly altering the rate of flow through the primary outlet. The assembly includes a vortex tube disposed within a cylindrical housing having primary and secondary outlets, and a pair of flow-dividing members within the housing, at least one of which is movably mounted, for controlling the temperature of the air discharged from the primary outlet by altering the proportions of hot and cold air flowing through the passages of such members.

A temperature-adjustable vortex tube assembly comprising a vortex tube having a generator body provided with a compressed air inlet and having coaxial and oppositely-directed tubular outlets for hot and cold air, respectively; a housing defining a chamber receiving said vortex tube; said chamber having a primary outlet and a secondary outlet; a first flow-dividing member disposed within said chamber and provided with a hot air passage and a cold air passage extending therethrough; means directing cold air from said cold air outlet of said vortex tube to said cold air passage of said first flow-dividing member and directing hot air from said hot air outlet of said vortex tube to said hot air passage of said first flow-dividing member; and a second flow-dividing member disposed within said chamber adjacent said first member and provided with a pair of separate passages extending therethrough; one of said passages of said second member communicating with said primary outlet and the other of said passages of said second member communicating with said secondary outlet; said first and second members being positioned and arranged so that air passing through the passages of said first member enter the passages of said second member and being movable relative to each other for selectively varying the proportions of air passing from the respective hot and cold air passages of said first member into each of said passages of said second member, whereby, the temperature of the air discharged from said primary outlet may be controlled by varying the relative positions of said first and second members to alter the proportions of hot and/or cold air flowing through said one passage of said second member and into said primary outlet.
