ABSTRACT:
Disclosed herein is a capacity-changing unit of an orbiting vane compressor that is capable of selectively accomplishing compression or communication in inner and outer compression chambers of a cylinder through simple manipulation of a valve, thereby easily changing the capacity of the orbiting vane compressor. The capacity-changing unit includes a smart control valve comprising a valve body disposed on the cylinder, a first actuating part formed at one side of the valve body for performing compression and communication in the inner compression chamber of the cylinder, and a second actuating part formed at the other side of the valve body for performing compression and communication in the outer compression chamber of the cylinder.
