Definitions

  • This invention relates to fluid displacement apparatus, and more particularly, to a mechanism for adjusting the angular relationship between scroll elements of a scroll type fluid displacement apparatus.
  • Scroll type fluid displacement apparatus are well known in the prior art.
  • U.S. Patent No. 801,182 disclose a device including two scroll members each having a circular end plate and a spiroidal or involute spiral element. These scroll members are maintained angularly and radially offset so that both spiral elements interfitto make a plurality of line contacts between their spiral curved surfaces, thereby to seal off and define at least one pair of fluid pockets.
  • the relative orbital motion of the two scroll members shifts the line contacts along the spiral curved surfaces and, therefore, the fluid pockets change in volume. Since the volume of the fluid pockets increases or decreases dependent on the direction of the orbiting motion, the scroll type fluid displacement apparatus can be used to compress, expand or pump fluids.
  • a scroll type compressor In comparison with conventional compressors of the piston type, a scroll type compressor has certain advantages, such as fewer parts and continuous compression offluid.
  • scroll type compressors have the problem that adjusting the angular relationship between the spiral elements is a difficult operation. If the angular relationship between the spiral element is in error, radial sealing between thetwo spiral elements is lost and fluid leakage occurs. As a result of this fluid leakage, the efficiency of the compressor is significantly reduced.
  • One solution to the problem of achieving the proper angular relationship between the scroll element is to reduce the permissible manufacturing tolerances of the component parts. The manufacturing of scroll compressor components, however, is already complicated and reducing tolerance would greatly increase manufacturing costs. Another proposed solution is to increase the tolerance of the angular relationship between the spiral elements. Such a solution has not proved satisfactory.
  • EP-A-61698 discloses an orbiting piston type fluid displacement apparatus having fixed and orbiting fluid displacement members, a driving mechanism connected to the orbiting member to drive the member in an orbital motion, and a rotation preventing/thrust bearing means for preventing rotation of the orbiting member.
  • the rotation preventing/thrust bearing means includes an orbital portion which is secured to the orbiting member, a fixed portion which is secured to a housing of the apparatus and a series of ball elements which are located between the orbital and fixed portions.
  • the fixed and orbital portions each include a ring formed with a plurality of holes or pockets and each ball element is engaged in one of the holes or pockets in the ring of the fixed portion and one of the holes or pockets in the ring of the orbital portion.
  • one technique to adjust the angular relationship is to provide a hole on the end wall surface of the spiral element of one scroll member, and to form a hole through the front end plate of the housing opposite to the hole in the scroll member.
  • the adjusting of the angular relationship between both scroll elements is effected by an angle adjusting member inserted into the holes from outside of the front end plate.
  • EP-A-99740 (Sanden), which is part of the state of the art according to Article 54(3) and (4) EPC, discloses a scroll type fluid displacement apparatus wherein a bore of predetermined depth is formed in a fixed scroll member and a front end plate of a housing is formed with a hole which extends through the plate. When assembling the apparatus, an adjustment member is inserted into the bore via the hole, thereby to set the angular relationship between the scroll members.
  • a scroll type fluid displacement apparatus including a first scroll member having a first end plate from which a first spiral element extends, a second scroll member having a second end plate from which a second spiral element extends, said first and second scroll members interfitting at an angular and radial offset to make a plurality of line contacts to define at least one pair of sealed off fluid pockets, a driving mechanism operatively connected to said second scroll member to effect orbital motion of said second scroll member while rotation of said second scroll member is prevented by a rotation preventing/thrust bearing mechanism, whereby the fluid pockets change volume, characterised by said first scroll member being formed with a bore having a predetermined depth, said second end plate of said second scroll member being formed with a penetrating hole, and a hole extending completely through a front end plate of a housing and being brought into substantial alignment with said bore and said penetrating hole by an adjusting member inserted into said bore and said penetrating hole through said hole in said front end plate during assembly of the apparatus,

  • An axial end surface of each bosses 203 is seated on the inner surface of end plate 121 of cup shaped casing 12 and is fixed to end plate 121 by bolts 23.
  • Fixed scroll 20 is thus fixed within cup shaped casing 12.

  • An eccentric hole 272 is formed in bushing 27 radially offset from the center of bushing 27.
  • Drive pin 132 is fitted into the eccentrically disposed hole 272 within which a bearing 29 may be applied.

  • Rotation preventing/thrust bearing device 22 is disposed between the rear end surface of front end plate 11 and the end surface of circular end plate 211 of orbiting scroll 21 on the side opposite spiral element 212.
  • Rotation preventing/thrust bearing device 22 includes a fixed portion, an orbital portion and a bearing element, such as a plurality of spherical balls.

  • Fixed race 221 and fixed ring 222 are attached to the axial end surface of annular projection by pins 223.
  • the orbital portion also includes an annular orbital race 224, which has one end surface fitted against an axial end surface of circular end plate 221, and an orbital ring 225 fitted against the other axial end surface of orbital race 224 to extend outwardly therefrom and cover the other axial end surface of orbital race 224.
  • a small clearance is maintained between the end surface of fixed ring 222 and the end surface of orbital ring 225.

  • the holes or pockets 222a on fixed ring 222 correspond to or are a mirror image of the holes or pockets 225a on orbital ring 225; i.e., each pair of pockets facing each other have the same size and pitch, and the radial distance of the pockets from the center of their respective rings 222 and 225 is the same; i.e., the centers of the pockets are located the same distance from the center of rings 222 and 225.
  • fixed scroll 20 is at least provided with a projection 205 projecting from the outer surface of spiral element 202, and preferably integral with it.

  • the adjust-. ment member 40 There is some play between the adjust-. ment member 40, the holes 113 and 214 and the bore 206.
  • the end plate 11 may be rotated slightly back and forth. Since, during operation of the apparatus, the balls 227 of the rotation preventing/thrust bearing device 22 usually interact between the edges of the holes 222a and 225a, without a gap, to prevent rotation of the orbiting scroll, the proper angular relationship between the fixed scroll 20 and the orbiting scroll 21 can then be established.
  • Drive shaft 13 is then rotated in the drive direction of the apparatus so as to push the spiral element 212 of the orbiting scroll 21 against the spiral element 202 of the fixed scroll 20.
  • the orbiting scroll 21 is ableto move around the adjustment member 40. Therefore, after the spiral element 212 has been fitted against the spiral element 202 of the fixed scroll 20, the orbiting scroll 21 is further rotated around the adjustment member 40 by rotation of the drive shaft. Because the orbiting ring 225 is fixed on the end plate 211 of the orbiting scroll 21, the orbiting ring 225 is rotated about the adjustment member 40 due to the rotating motion of the orbiting scroll 21.
  • the angular relationship between both scrolls can therefore be adjusted and set by above-mentioned operation.
  • the adjustment member 40 is removed from the compressor unit.
  • the offset between the scrolls is fixed by tightening the fastening means.
  • a plug 41 is screwed into a screw portion 113a of the hole 113, and the seal ring 42 is disposed within an annular depression 113b formed at end portion of hole 113 to form a seal between the plug 41 and the hole 113 to seal off the inner chamber of cup-shaped casing 12.
