摘要： PROBLEM TO BE SOLVED: To provide a support structure for a compressor in which resistance force upon starting of an electric motor driven element is reduced, and transmission of vibration of a fixing nut and a bolt of support and installation means to a substrate is reduced. SOLUTION: For supporting and installing a fully closed compressor 1 on a substrate 3 a mounting plate 4 is first fixed to a casing of the fully closed compressor 1. Then, part of a lower end of a liquid encapsulated vibrationproof apparatus (viscous mount) 2 is buried in the substrate 3, and then a shaft of the viscous mount 2 is supported on the mounting plate 4 of the casing of the fully closed compressor 1 and are fixed with a fixing nut and a bolt. The viscous mount 2 is inserted into an internal surface of a cylindrical case by hermetically sealing a disk portion formed on a lower end integrally with a shaft. Passages communicating an upper space and a lower space of the case are provided at a plurality of portions. There is encapsulated a gelated highly viscous fluid such as silicon oil. A movable rubber is covered over an upper end of the case, penetrating the shaft and surrounding the case.

摘要： PROBLEM TO BE SOLVED: To raise the initial seal performance, and also maintain the seal performance for a long period, in a noncontact type of seal mechanism. SOLUTION: The peripheral face of a piston 11 is provided with a clearance seal 12. Flat parts 55 which oppose the inwall face of a cylinder 6 a specified initial clearance s1 apart and are flat in cross section are made on both sides of the clearance seal 12. A recess 57 where the sectional form is in the shape of an inward three-dimensional curve is made between both flat parts 55 and 55. The recess 57 is made so that the quantity of leaked fluid may be constant by seal length increasing accompanying the increase of the area of the flat parts 55 when the clearance seal 12 are worn away and the clearance increases.

摘要： PROBLEM TO BE SOLVED: To prevent the production of fire even if combustible refrigerant is leaked from a pin hole generated in a hermetic compressor, and ensure safety by setting the welding part of a sealed container of the hermetic compressor to a part formed lower than the terminal part of the hermetic compressor. SOLUTION: In a hermetic compressor 1 for a refrigerating air conditioner in which a combustible refrigerant is used, an electric motor and a compressive mechanism are housed inside a sealed container 2. The sealed container 2 consists of an upper shell part 3 and a lower shell part 4, the compressive mechanism and the electric motor are housed in the lower shell part 4, and then, it is covered with the upper shell part 3, and the joining part 5 thereof is sealed by welding. A glass terminal part 6 is installed on the upper shell part 3. In this case, the joining part 5 is arranged lower than the glass terminal part 6. It is thus possible to prevent combustible gas leaked from the pin hole of the joining part 5 from becoming the mixing ratio of air in a combustible range, and it is possible to prevent the production of fire even if combustible refrigerant is leaked so as to ensure the safety.

摘要： PROBLEM TO BE SOLVED: To enhance the assemblability and the compression efficiency. SOLUTION: An expansion mechanism part 9 is assembled with reference to a first rotary shaft 19 while a compression mechanism part 11 is assembled with reference to a second rotary shaft 63. The first rotary shaft 19 of the expansion mechanism part 9 is coaxially coupled to the second rotary shaft 63 of the compression mechanism part 11 within a closed casing 7 by means of a joint 65 which restrains the transmission of heat from the first rotary shaft 19 to the second rotary shaft 63. The coupled outer peripheral parts 93 of the expansion mechanism part 9 and the compression mechanism part 11 are supported, being clamped between superposing coupling parts 97 of the closed casing 7.
