Abstract: A compressor is provided. The compressor may include a fixed wrap, and an orbiting scroll having an orbiting wrap engaged with the fixed wrap to form compression chambers. The fixed wrap and the orbiting wrap may have irregular wrap curves. At least one interference avoiding portion at which a spacing between the wraps is greater than an orbiting radius or at least one gap compensating portion at which the spacing between the wraps is smaller than the orbiting radius, in a state in which a center of the fixed scroll and a center of the orbiting scroll are aligned with each other, may be provided on a sidewall surface of the fixed wrap or the orbiting wrap, whereby frictional loss or abrasion due to interference between the wraps or a refrigerant leakage due to a gap between the wraps may be prevented.

Abstract: A compressor includes a rotation shaft, a drive unit, and a compression unit. The compression unit includes a fixed scroll, an orbiting scroll, a main frame that is disposed on the fixed scroll, and an Oldham's ring coupled to the orbiting scroll and the main frame and configured to restrict rotation of the orbiting scroll. The Oldham's ring includes a ring body disposed between the orbiting scroll and the main frame, keys that protrude from the ring body that are each coupled to the orbiting scroll or the main frame, and caps that are inserted into the main frame and that each have (i) a coupling hole that receives a key among the keys and (ii) a machined portion that faces the coupling hole and that is spaced apart from at least a portion of an outer surface of the key.
