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.

Abstract: A scroll compressor is provided that may include a frame; a non-orbiting scroll provided with a non-orbiting wrap formed on a first side surface of a non-orbiting end plate in an axial direction; an orbiting scroll provided with an orbiting wrap formed on a first side surface of the orbiting end plate in the axial direction and engaged with the non-orbiting wrap to form a compression chamber; a plurality of first guides disposed between the frame and the non-orbiting scroll to be located radially outward from the non-orbiting wrap; and a plurality of second guides provided on the orbiting end plate to be located radially outward from the orbiting wrap, respectively, so as to allow an orbiting motion of the orbiting scroll together with the first guides.

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.
