Abstract:
A structure of vortex compressor comprising: at least one threaded hole provided in a positioning pillar of a frame; a retainer packing is locked to the frame with a screw, an ideal spacing is defined between the positioning pillar of the frame a vortex seat, and the ideal spacing being limited in position by the retainer packing that restricts the vortex seat, wherein, upon assembling of the frame and the retainer packing, the screw is easily received into the threaded hole through a deformation spacing to provide a locking effect in the threaded hole as required, thus to fix the retainer packing to the frame for quality assurance of the assembly of the vortex seat; the installation of the deformation spacing also effectively eliminates flaws of narrowing spacing of revolution between deformed positioning pillar and the vortex seat or operation noise and awkward operation of the compressor due to unpredictable change, wherein the deformation spacing is formed on the vortex seat in relation to an inner edge at an end of the threaded hole to receive the placement of the screw for facilitating the placement of the screw into the threaded hole, and for providing the locking effect when the screw is completely received in the threaded hole for quality assurance of the assembly of the vortex seat.
