SCROLL COMPRESSOR
The present invention discloses a scroll compressor. At least two shrink belts (23′, 23″, 26, 26′, 28, 28′) are provided around the outer periphery of said fixed scroll between the outer periphery of said fixed scroll (2) and the inner wall surface of the upper cap (1) of the scroll compressor. The at least two shrink belts are annular, and are in interference fit between the outer periphery of said fixed scroll and the inner wall surface of the upper cap. The at least two shrink belts include a main shrink belt (23′, 23″, 28) and an assistant shrink belt (26, 26′, 28′). The main shrink belt and the assistant shrink belt are arranged side by side in the axial direction, that is, in the vertical direction of the fixed scroll, and the main shrink belt and the assistant shrink belt are spaced apart from each other by a distance. In this way, it is allowed to add other special structure (e.g., an additional fluid passage) to the fixed scroll, reduce the deformation of the fixed scroll, and improve the performance and the reliability of the scroll compressor.
