Document Type and Number:
WIPO Patent Application WO/2023/038293
Kind Code:
A1
Abstract:
According to the present invention, provided is a scroll compressor in which a plurality of fixing protrusions are provided spaced apart from each other in a key that constitutes an Oldham ring, and an orbiting scroll, to which the key is coupled, or a ring body of the Oldham ring may be provided with a plurality of fixing grooves which are spaced part from each other and into which the plurality of fixing protrusions are respectively inserted and fixed. Accordingly, the weight of the Oldham ring is reduced, thus improving motor efficiency, and it is possible to prevent the key constituting the Oldham ring from becoming separated from the orbiting scroll or the ring body due to a difference in thermal strain.
