    Abstract: A single-component refrigerant mainly comprising hydrofluoroolefin having a carbon-carbon double bond or a mixture refrigerant including this refrigerant is used as a refrigerant. An axial length L of a discharge port 14 is set to be less than a thickness H of a member in which the discharge port 14 is formed, thereby making it possible to reduce a length of the discharge port in a direction of a flow passage to reduce a pressure loss and restrain an unnecessary pressure increase in a compression mechanism 4 to reduce a temperature increase of the refrigerant. At the same time, because a volume of the discharge port 14 filled with a high-pressure gas refrigerant can be made smaller, the high-pressure gas refrigerant remaining in the discharge port 14 after completion of a discharge process in the compression mechanism 4 is restrained from flowing back toward a low-pressure side compression chamber 9. Accordingly, a temperature increase of the refrigerant caused by re-expansion and re-compression can be also restrained.

    Abstract: A scroll compressor employs therein a refrigerant having a small global warming potential and a small ozone depletion potential and mainly comprising hydrofluoroolefin having a carbon-carbon double bond. A stationary scroll 12 has and end plate and a discharge port 18 defined in the end plate at a central portion thereof so as to open into a discharge chamber. The stationary scroll 12 also has a bypass hole 68 defined in the end plate to allow a plurality of compression chambers 15 to communicate with the discharge chamber before the compression chambers 15 communicate with the discharge port 18. A check valve 19 is provided on the bypass hole 18 to allow the refrigerant to flow from the compression chambers to the discharge chamber. This construction can restrain a baneful influence on the global environment, reduce a temperature increase caused by excessive compression, and restrain decomposition of the refrigerant even in long-term use.

    Abstract: PROBLEM TO BE SOLVED: To maintain the sealing performance of a compressed space while favorably maintaining a sliding condition in a compression mechanism part. SOLUTION: The oil retentivity of a sliding surface is improved and lubricity is enhanced by arranging a micro hollow 22 in a set range T on a plane surface of a lower bearing part 2. Therefore, the sliding resistance relative to a sliding surface 3c on an axial side of a crankshaft is reduced. Moreover, the set range T of the micro hollow 22 is located inside the sliding range of the sliding surface 3c on the axial side of the crankshaft and a seal length between the high pressure area H and an intake chamber 12 can be assured. Therefore, the prevention of a decrease in the performance of a compressor due to a leakage is enabled. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a hermetic compressor in which minimum necessary oil supply to a compression chamber in a suction stroke is desired in consideration of loss due to the heating of operating fluid and oil biting during compression, and the amount of oil supply per rotation should be increased in conditions of low rotating speed and high differential pressure because a leakage amount is determined depending on a pressure difference and a leakage time. SOLUTION: An oil supply passage is provided for supplying oil to the compression chamber while keeping a crank angle section constant after completing the close-in, thus improving the sealing performance of the compression chamber particularly in the conditions of low speed and high differential pressure while suppressing the heating of the operating fluid during suction.
