Abstract:
A scroll compressor, comprising:a main frame having an inner peripheral surface, a regulation surface, and a contact surface, an orbiting-scroll disposed above the main frame and having a base plate back surface facing the regulation surface and the contact surface, an Oldham-coupling ring disposed between the contact surface of the main frame and the base plate back surface of the orbiting-scroll for preventing rotation of the orbiting-scroll, and a thrust ring including a main body to be fitted in the inner peripheral surface of said main frame, and a flange portion formed at one side of the main body and slidably contacting the base plate back surface to thereby partition the base plate back surface into a plurality of pressure spaces, said flange portion having an outer diameter greater than an outer diameter of said inner peripheral surface and being disposed between the base plate back surface and the regulation surface flush with the contact surface where the Oldham-coupling ring is disposed so that a movable range of said thrust ring in the axial direction is regulated.
