  • Patent number: 12234821
    Abstract: Disclosed are a scroll compressor and a method for assembling a non-orbiting scroll of the scroll compressor. The scroll compressor includes: a scroll mechanism including a non-orbiting scroll which includes a non-orbiting scroll end plate and a non-orbiting scroll wrap and an outer peripheral wall; and a main bearing seat for supporting the scroll mechanism including a main body part and an axial seat portion whose inner peripheral surface is formed with a circumferential annular groove. The scroll compressor further includes an elastic ring provided between the outer peripheral wall and the axial seat portion and a push structure for forcing the elastic ring to expand radially outward, so that a part of the elastic ring in a radial direction is inserted into the circumferential annular groove to limit axial movement of the non-orbiting scroll away from the main bearing seat.
