Claim Text:
1. A scroll compressor, comprising: a fixed scroll having a fixed wrap; and an orbiting scroll having an orbiting wrap engaged with the fixed wrap to form compression chambers, and the orbiting scroll performing an orbital motion with respect to the fixed scroll, wherein the fixed wrap and the orbiting wrap comprise a plurality of sections including a first constant section formed as an involute curve and with a wrap thickness that is constant in a lengthwise direction, a second constant section formed as an involute curve and with a wrap thickness that is constant in the lengthwise direction, and a variable section formed as a smooth transition curve between the first constant section and the second constant section and with a wrap thickness that increases in the lengthwise direction, wherein the first constant section, the variable section and the second constant section are consecutively formed in a direction from a wrap final end to a wrap initial end, wherein the first constant section is formed from the wrap final end to a predetermined crank angle, the variable section is formed from an end of the first constant section to a predetermined crank angle, and the second constant section is formed from an end of the variable section to the wrap initial end, wherein the wrap thickness of the first constant section is smaller than that of the second constant section, and wherein the wrap thickness of the variable section is continuously increased along an entire length of the variable section between the first constant section and the second constant section.
