SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2021/208386
Kind Code:
A1
Abstract:
A scroll compressor, comprising: a compression mechanism, the compression mechanism comprising a fixed scroll (2) and a movable scroll (3), and the movable scroll (3) being configured to be able to orbit relative to the fixed scroll (2) to compress a working fluid; a housing (1), the housing (1) defining an internal space for accommodating the compression mechanism; a main bearing seat (5), the main bearing seat (5) being fixed to the housing (1) and supporting the movable scroll (3); and an axial flexible installation mechanism, the fixed scroll (2) being connected to the main bearing seat (5) by means of the axial flexible installation mechanism to enable the fixed scroll (2) to move a predetermined distance in the axial direction. The axial flexible installation mechanism comprises: a fastener (17; 27; 37; 47; 57; 67) having a head (171; 271; 371; 571; 671), a sleeve (19; 29; 39; 59; 69) provided on the outer periphery of the fastener (17; 27; 37; 47; 57; 67), and a backing plate part (18; 28; 38; 48; 58; 68) disposed at least partially between the head (171; 271; 371; 571; 671) of the fastener (17; 27; 37; 47; 57; 67) and the sleeve (19; 29; 39; 59; 69) in the axial direction; the backing plate part (18; 28; 38; 48; 58; 68) can be joined with the housing (1); and the housing (1) can provide radial support for the backing plate part (18; 28; 38; 48; 58; 68). The compressor lowers both the sliding risk of the sleeve and the risk of failure of the bolt and the main bearing seat caused by ruptures.
