Definitions

  • the present invention [1]
  • the scroll compressor comprising a fixed scroll and a rotating scroll force, particularly a spring for a chip seal provided on a sliding surface of a blade tip of the scroll has been improved. Squeeze mouth pertaining to compressors.
  • each of the fixed scroll and swivel scroll 4 which constitute the compression mechanism, slides on the sliding surface at the tip of each blade.
  • a sealing member is provided for the purpose of sealing the moving part (only the swivel scroll side is shown).
  • a groove 18 is provided on the sliding surface 5 at the tip of each blade, and a chip seal 14 is attached to this groove.
  • a spring member 15 is provided between the groove and the chip seal in order to press the chip seal against the sliding surface to further enhance the sealing property.
  • the spring member 15 (the tip seal needs to be pressed uniformly against the sliding surface 0, which is cut and raised at appropriate intervals along the center line as shown in Fig. 2) It is appropriate to use a cut-and-raised spring where the fixed and swivel scrolls are mirror-symmetrical to each other.
  • the shape of the spring must be the same. ⁇ and turning scrolling must be created separately. Therefore, it takes time to create a spring member.
  • the present invention aims to reduce the time and effort required to produce the above-mentioned spring member, and to produce a scroll compressor more efficiently.
  • a spring member for either a fixed scroll or a revolving scroll is created, and this is used as a tip seal spring for the other scroll.
  • FIG. 1 is an exploded perspective view of a seal portion of a conventional compressor.
  • FIGS. 2 (a) and 2 (b) are perspective views of a main part of a conventional example.
  • FIG. 3 is a longitudinal section of a compressor of one embodiment of the present invention.
  • 3 ⁇ 4 Fig. 4 (a) and (b) are perspective views of the seal part of the compressor.
  • the compression mechanism 2 has a fixed scroll 3 and a rotating scroll 6 having a rotating blade 6 which meshes with the fixed scroll 3 to form a plurality of compression working spaces 5.
  • U and an Oldham ring 7 that prevents the rotation of the revolving scroll 4 from rotating and performs only revolving.
  • the revolving drive shaft 8 provided on the opposite side to the revolving blade 6 is a crank. It is fitted into an eccentric bearing 10 formed at one end of the shaft 9. Refrigerant sucked from the suction port 11 of the compressor mechanism 2 is compressed in the compression work space 5 and discharged from the discharge port 12. Fig.
  • the force is different, and it has the same sealing performance as the conventional one in the same direction, so that the labor for creating this spring member can be shortened and the cost can be reduced.
