Patent ID: 7341437

Claim:
A capacity changer of an orbiting vane compressor, comprising: inner and outer compression chambers provided in a cylinder, the inner and outer compression chambers being separated from each other by a circular vane of an orbiting vane positioned within an annular space of the cylinder; inner and outer inlet ports provided at an upper part of the cylinder, the inner inlet port communicating with the inner compression chamber and the outer inlet port communicating with the outer compression chamber; inner and outer outlet ports provided at the upper part of the cylinder, the inner outlet port communicating with the inner compression chamber and the outer outlet port communicating with the outer compression chamber; and a control valve comprising: a valve body provided on the cylinder; a first actuator provided at a first side of the valve body, the first actuator being in communication with and compressing a fluid within the inner compression chamber of the cylinder, the first actuator being configured to reciprocate linearly as a second actuator provided at a second side of the valve body is actuated; and the second actuator being in communication with and compressing a fluid within the outer compression chamber of the cylinder, the second actuator being configured to reciprocate linearly as the first actuator is actuated.
