Helical compression mechanism is the newly developed one that can compress gas by using helical components. As helical shape has uneven pitch, the volume of each chamber becomes smaller according to the revolution, and the gas is transferred and compressed continuously. This mechanism was designed in 1987, and the compressor with lubricant was developed and manufactured for refrigerator first in the world in 2000. And, oil-less air compressor using helical mechanism was also developed and manufactured in 2003. This oil-less helical compressor doesn't contain oil at all. To achieve high performance and reliability in oil-less compressor, gas seal, wear durability, and cooling are usually major problem, because contribution of oil to these functions can not be expected. This study focuses on the performance related to these problems, and investigates flow performance at variable revolution, and compression process details of oil-less helical compressor by measuring P-V diagram.
