Abstract
Disclosed herein is a capacity-changing unit of an orbiting vane compressor that is capable of performing normal operation and no-load operation in inner and outer compression chambers through simple manipulation of a rotary valve plate, thereby easily changing the capacity of the compressor according to operation modes. The capacity-changing unit comprises a rotary valve plate disposed between a cylinder and a subsidiary frame for opening or closing a communication channel connected between an inlet port of the cylinder and inner and outer outlet ports of the cylinder as an actuator is rotated in alternating directions. Consequently, the present invention has the effect of reducing power consumption and preventing reduction in service life of the parts of the orbiting vane compressor due to repetitive on/off operation of the orbiting vane compressor, and therefore, improving the performance and reliability of the orbiting vane compressor.
