Scroll compressor

A scroll compressor, comprising:

• a non-orbiting scroll and an orbiting scroll, wherein the orbiting scroll is configured to orbit relative to the non-orbiting scroll to compress a fluid;
• a main bearing seat for supporting the orbiting scroll;
• an axial flexible mounting mechanism via which the non-orbiting scroll is connected to the main bearing seat, so that the non-orbiting scroll is capable of moving a predetermined distance in an axial direction,
• wherein the axial flexible mounting mechanism comprises a bolt and a sleeve arranged on the outer periphery of the bolt,
• wherein the sleeve comprises in the axial direction a first section in contact with the main bearing seat and a second section in contact with the non-orbiting scroll, wherein the first section is configured such that the bending stiffness in a radial direction is different from the bending stiffness in a tangential direction,
• wherein:
• for a scroll compressor where the sleeve is subjected to a larger load in the radial direction, the sleeve is configured to have a larger bending stiffness in the radial direction, and for a scroll compressor where the sleeve is subjected to a larger load in the tangential direction, the sleeve is configured to have a larger bending stiffness in the tangential direction.
