Abstract
There is provided a scroll compressor comprising: a fixed-side member comprising a casing and a fixed scroll member provided in the casing; a driving shaft rotatably provided in the casing; an orbiting scroll member orbitably provided at a distal end of the driving shaft; a suction opening provided in the fixed-side member; and a discharge opening provided in the fixed-side member. Each of the scroll members includes an end plate and a spiral wrap portion standing on the end plate. The wrap portion of the orbiting scroll member is adapted to overlap the wrap portion of the fixed scroll member so as to define a plurality of compression chambers. The suction opening communicates with the outermost compression chamber, and the discharge opening is adapted to discharge a compressed gas from an inner compression chamber. A seal member comprising an elastic member is provided around an outer circumferential surface of the orbiting scroll member, so as to seal the compression chambers relative to outside air between the orbiting scroll member and the fixed-side member. The seal member has an opening on a radially inner side thereof and has a generally U-shaped cross-section.
