Conservation of energy and the saving of resources are executed in refrigeration cycle equipments aiming at the environmental protection. Especially, the effect of the improvement of the compressor, which is a key device of the refrigeration cycle equipment, is large, so development of new technology for making both higher efficiency and compact is pressing need. We have developed a Twin Rotary Compressor with a New Heat Caulking Fixing Method, which is the specific technology for fixing the mechanical component and shell, instead of Arc Spot Welding Method. This method greatly reduces the stress and strain that occurs to the mechanical component when fixing the shell. We expanded the stroke volume at the same outer diameter of the shell and improved compressor efficiency by thinning the mechanical component at the same stroke volume. This paper introduces the mechanism of the new fixing method and the effective of use gained by this method.
