    Abstract: PROBLEM TO BE SOLVED: To enhance the efficiencies of manufacturing and assembling works and achieve cost-reduction by simplifying the structure of the device, while inhibiting leak of working fluid. SOLUTION: A 1st housing member 1 and a 2nd housing member 2 are formed of an aluminum alloy having a high coefficient of linear expansion, and each cam ring 3 is formed of a cast iron having a low coefficient of linear expansion. The can ring is fit to the periphery of projected parts 8, 11 of both the housing members, and rotatably holds internal and external gears 13, 14 driven by a drive shaft 15 in the inside. By thermal expansion, a 1st and a 2nd contact faces 8a, 11a respectively of both the projected parts reduce the side clearance between both sides of both the contact faces and the internal and external gears to inhibit leak of the working fluid from the clearance.

    Abstract: A hermetic compressor is provided to use a fixing bolt or a bush formed with a material having a thermal expansion coefficient higher than that of a cylinder for keeping stable coupling between the fixing bolt and a bolt coupling hole in spite of different thermal expansion of the cylinder and the fixing bolt, thereby preventing deterioration of compressor performance. A hermetic compressor includes a cylinder(20) having a compression chamber, and a cylinder head(40) coupled with the cylinder for sealing the compression chamber. A fixing bolt(50) is coupled with the cylinder to couple the cylinder head to the cylinder and formed of a material having a thermal expansion coefficient higher than that of the cylinder. A bolt coupling hole(24) is formed in the cylinder for coupling the fixing bolt. A bush(60) is interposed between the fixing bolt and the bolt coupling hole and formed of a material having a thermal expansion coefficient higher than that of the cylinder.
