Abstract
A scroll compressor is provided, in which a fastening member fixing portion of a valve fastening member fixes the valve fastening member to a non-orbiting scroll, a valve fixing portion of the valve fastening member fixes a bypass valve to the non-orbiting scroll, and the fastening member fixing portion is located axially farther away from a compression chamber than the valve fixing portion is. This may secure a fastening thickness by which the valve fastening member that fixes the bypass valve is fastened to the non-orbiting scroll and reduce a plate thickness at a portion where bypass holes and/or a discharge port are formed, thereby decreasing dead volumes in the bypass holes and/or the discharge port.
