This paper proposes a new type of compressor that can discharge air in alternate directions. This compressor can operate the direction/speed of a cylinder by changing the clockwise/counterclockwise rotational direction and the rotational speed of the compressor, and also does not need additional solenoid control valves. The key issue here is to develop an alternate direction air compressor having effective performance. In this report, we verify the fundamental characteristics and advantages of this compressor. We also investigate the possibility a cylinder system using this new type of compressor.
