Abstract: A scroll compressor is provided in which a center of a back pressure chamber is eccentrically disposed relative to a center of a fixed scroll. For example, the center of the back pressure chamber may be moved towards a center of an orbiting scroll at a time of discharge, thereby preventing displacement of the fixed scroll and ensuring stability in orbital movement of the orbiting scroll.

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.

Abstract: A compressor may include a casing, and a compression device installed inside of the casing and that compresses the refrigerant while rotating by receiving a rotational force of an electric motor through a rotational shaft. A high/low pressure separation plate may be installed at an upper portion of the compression device, and an insulation plate may be provided to block the high/low pressure separation plate and the suction tube from each other by being located therebetween. The insulation plate may reduce heat transfer between a refrigerant discharge space having a high temperature located at the upper portion of the high/low pressure separation plate and a refrigerant suction space having a relatively low temperature located at a lower portion of the high/low pressure separation plate.

Abstract: A scroll compressor may include a frame, an orbiting scroll provided with at least one first key groove, a non-orbiting scroll provided with at least one second key groove and coupled to the orbiting scroll to form a compression chamber, and an anti-rotation ring disposed between the frame and the orbiting scroll. The anti-rotation ring may include a ring, at least one first key that axially extends from a first surface of the ring and slidingly coupled to the at least one first key groove of the orbiting scroll, and at least one second key that axially extends from the first surface of the ring and slidingly coupled to the at least one second key groove of the non-orbiting scroll. The first and second keys may be provided along a circumferential direction. This may allow processability of a one-way anti-rotation ring. Further, increase in weight may be prevented while reducing deformation by providing a weight-reduced portion in addition to a reinforcing portion.
