摘要： A scroll compressor and a refrigerating machine including the same are provided. In the scroll compressor, an oil supply hole formed in an orbiting scroll guides oil from a space between a frame and the orbiting scroll to a space between a fixed scroll and the orbiting scroll, and an oil supply groove formed at the fixed scroll maintains communication with the oil supply hole, thereby rapidly supplying oil to a bearing surface between the fixed scroll and the orbiting scroll before the oil is introduced into a back pressure chamber. This enhances compressor efficiency by effectively preventing frictional losses and refrigerant leakage in such a compressor, and enhances energy efficiency for a refrigerating machine using such a compressor.

摘要： A hermetic compressor and a refrigeration cycle device having the same are provided. An oil separator is installed either outside or inside of a casing to separate oil from a discharged refrigerant and an oil pump driven by a driving force of a motor is used to recollect the oil separated in the oil separator, whereby the separation between oil and refrigerant can effectively be performed and also a fabricating cost can be reduced. Also, an introduction of the separated refrigerant back into the compressor can be prevented so as to improve a cooling capability of the refrigeration cycle device. In addition, the oil pump is driven by the driving force of the motor, resulting in a simple configuration of the compressor and a reduction of a fabricating cost of the compressor.

摘要： A scroll compressor and a refrigerating apparatus having the same are provided. In the scroll compressor, an angle formed between an injection passage that guides refrigerant from a condenser back into an intermediate compression chamber and a back pressure passage that guides refrigerant from the intermediate compression chamber into a back pressure chamber may be designed so as to prevent leakage of refrigerant from the intermediate compression chamber into the back pressure chamber. This allows an appropriate pressure to be maintained the back pressure chamber, and increases an amount of refrigerant supplied into the compression chambers, thereby improving performance of the scroll compressor and a refrigerating apparatus in which such a scroll compressor is installed.
