Abstract:
1. A compressor, comprising: a casing; a fixed scroll fixed in the casing, the fixed scroll including a fixed wrap having a thickness that varies along a compression path; an orbiting scroll having an orbiting wrap engaged with the fixed wrap so as to define at least one compression chamber together with the fixed wrap, the orbiting wrap having a thickness that varies along the compression path; a shaft having an eccentric portion coupled to the orbiting scroll such that the eccentric portion overlaps the orbiting wrap in a lateral direction of the compressor; a driver that rotates the shaft; a discharge hole and at least one bypass hole each formed in the orbiting scroll, in communication with a discharging space of the compressor; and an upper frame provided in the casing, wherein the upper frame divides an inner space of the casing into the discharging space and a suctioning space, wherein the upper frame comprises a discharge passage that provides communication between the discharge hole formed in the orbiting scroll and the discharging space formed above the upper frame, and wherein the discharge passage formed in the upper frame also provides communication between the at least one bypass hole formed in the orbiting scroll and the discharging space formed above the upper frame.
