The scroll compressor is now becoming extremely popular in air conditioning and refrigeration in conjunction with the adoption of the heat pump, especially in North America and in Japan. This is primarily due to its higher efficiency and its low noise/vibration characteristics. The scroll compressor technology can be applied in many ways. The authors have developed a scroll vacuum pump using the corotating principle. Although the scroll corotation mechanism is widely known, this is the first attempt at using and developing it for commercial use. Two scrolls rotate around their own axes and no crank mechanism is necessary. The compliant sealing mechanism can also be employed with this vacuum pump. In the present paper, the authors describes the characteristics of the corotating scroll vacuum pump which can be operated in wet and other harsh physical environments, i.e., with contamination, rust, and high suction pressure.
