Abstract
The compression capacity of a rotary compressor may be changed by a cylinder bypass system. The change of compression capacity is achieved by a slide wall member which composes part of an inside wall of a cylinder containing a compression mechanism and which is movable, thereby bypassing gas being compressed to a suction side of the compressor. The slide wall member is caused to slide forward by gas pressure applied and to slide backward by a spring force. By controlling such gas pressure, the capacity of the compressor may be changed. A relatively large opening is formed in the cylinder when the slide wall member is moved backward, so that the compression capacity can be greatly reduced without a large decrease in efficiency.
