Abstract
A scroll compressor is provided that may include a motor; an orbiting scroll; a fixed scroll coupled to the orbiting scroll, and forming a compression chamber together with the orbiting scroll; a frame coupled to the fixed scroll, and configured to support the orbiting scroll; a sealing member mounting groove having a ring shape, and formed on a first surface of the frame contacting the orbiting scroll, or a second surface of the orbiting scroll contacting the frame; and a sealing member including a first sealing portion formed in a ring shape, inserted into the sealing member mounting groove so as to be moveable in an axial direction, and configured to perform a sealing operation between the frame and the orbiting scroll in the axial direction and including a second sealing portion extending from the first sealing portion in the axial direction, and configured to perform a sealing operation between the frame and the orbiting scroll in a radial direction by contacting an outer side wall surface of the sealing member mounting groove A thickness of the second sealing portion in the radial direction may be smaller than a thickness of the first sealing portion in the axial direction.
