VORTEX APPARATUS Russian patent published in 2010 - IPC B01D45/00 

FIELD: mechanical engineering.

SUBSTANCE: invention refers to vortex apparatus. The apparatus contains a casing with covers, nipples, partitions, a vortex tube with a cold flow tube with a torsional device at one end and the other end withdrawn through the upper partition into the cold flow chamber and equipped with a device for control of flow of the original compressed gas with a hot flow tube installed in the lower partition with a cylindrical shell inside at the inlet wherein the torsional screw device is freely inserted, a travelling valve with a rod equipped with an axial movement mechanism. At a distance from the torsional device the hot flow tube has crosswise slits and a ring-shaped chamber with diversion channels encompassing them. The device for control of flow of the original compressed gas is designed as a bellow with a calibrated spring function, its extension or compression generating an alternate/reciprocal motion of the torsional screw device inside the cylindrical shell. The length pf their travel is ensured by the stem attached at the cold flow tube outlet in a crosspiece and freely travelling along its axis through the tubes in crosspieces al the bellow ends and having a rest at a distance from its lower crosspiece at its free end. The mechanism of axial travel of the valve with a rod is designed as a bellow with a calibrated spring function fitted onto the rod and attached to it with its upper choke plug, he bellows mounted on a support attached to the casing flange.

EFFECT: increased reliability and simplification of assembly.
