PROBLEM TO BE SOLVED: To provide a compressor that secures low-torque variation and a suction capacity ratio.SOLUTION: A compressor includes a revolving scroll revolving with an eccentric shaft and a stationary scroll. In the revolving scroll, a plurality of volute laps comprising an involute curve are formed on the same plane. The involute curve of each lap is formed so that the elongation open angle increases from the forefront of the lap to the end part in winding of the lap on the axis side of the eccentric shaft. One of the external walls of the winding end part of each lap and the internal wall of the other are coupled together with a smooth curve. The lap shape of the stationary scroll is formed of the envelope of loci drawn by the revolving motion of the laps of the revolving scroll. |
