Abstract
A scroll compressor is provided. The scroll compressor may include a fixed scroll having a fixed wrap with a thickness that varies along a compression path and a disk having a discharge and at least one bypass hole formed therein, and an orbiting scroll having an orbiting wrap with a thickness that varies along the compression path and that orbits with respect to the fixed scroll to define a compression space between the respective wraps. The compressor may also include a rotation shaft coupled to the orbiting scroll, and a driver that rotates the rotation shaft. A diameter of each bypass hole may be greater than one third of an effective diameter of the discharge hole.
