Abstract
An improved structure of vortex compressor provided with at least one threaded hole to the positioning pillar of a frame, a retainer packing locked with the screw to the frame to define an ideal spacing between the pillar and a vortex seat, and the ideal spacing being limited in position by the packing to restrict the vortex seat characterized by a deformation spacing slightly larger than the diameter of that of the prior art being provided to the threaded hole on the inner edge at the end receiving the screw to absorb squeezing produced by placement of the screw for quality assurance of the assembly of the vortex seat while eliminating the flaws of narrowing spacing of revolution between deformed positioning pillar and vortex seat or operation noise and awkward operation due to unpredictable change.
