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.
