摘要： PROBLEM TO BE SOLVED: To provide a compressor with a compression mechanism part whose bearing mechanism is reliably lubricated. SOLUTION: In the compression mechanism part 13 of the compressor 11, an oil receiving part 71 is formed opening to an intermediate chamber 29 to receive lubricating oil flowing down from the side of a motor part 14 along the inner peripheral face of a shell housing 12. A refrigerant passage 74 is formed to communicate the intermediate chamber 29 with a compression chamber suction passage 56 so that the refrigerant flowing down from the side of the motor part 14 passes therethrough. A lubricating oil passage 75 separate from the refrigerant passage 74 is formed ranging from the oil receiving part 71 to bearings 32, 48, 52 in communication with the inside of the compression mechanism part 13.

摘要： PROBLEM TO BE SOLVED: To provide a compressor for reducing pressure loss of an exhaust system.
SOLUTION: An exhaust passage 283 is partly opened in a side wall face 257b from an extending direction 271a of a surface of a stopper 271 in an opposite side of a discharge hole 253 to the side of the discharge hole 253. A refrigerant introduced from the discharge hole 253 to a discharge chamber 257 mostly flows from a downstream end of the discharge hole 253 in a direction 270a of a tip side of a reed valve 270, and afterwards goes down along the side wall face 257b and flows into the exhaust passage 283. Accordingly the refrigerant is hard to be distributed around the reed valve 270 and the stopper 271 and is hard to be brought round to a backside of the stopper 271. Thus vortex flow or the like of the refrigerant in the discharge chamber 257 can be restrained and the pressure loss of the exhaust system can be reduced.

摘要： PROBLEM TO BE SOLVED: To prevent seizure of a connecting part by supplying a sufficient amount of lubricating oil to the connecting part of a swirl scroll and a shaft.
SOLUTION: A communicating passage 24 introducing intake refrigerant communicates with a tip side of a boss part 14c. Therefore, the intake refrigerant flowing through the communicating passage is divided into flows, that is, a flow flowing into the boss part 14c to lubricate and cool a bearing 15 or the like before flowing out of the boss part 14c from a discharge port 14d to lubricate and cool a thrust receiving mechanism 17, and then sucked into a scroll type compression mechanism 2, and a flow directly supplied around the thrust receiving mechanism 17 through clearance 25 to lubricate and cool the thrust receiving mechanism 17 before sucked into the scroll type compression mechanism 2. Since the sufficient amount of lubricating oil is surely supplied to the bearing 15 or the like, abnormal abrasion of the bearing 15 or the like can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a compressor capable of improving mountability by preventing enlargement of a build due to a projectingly provided delivery pipe.
SOLUTION: The delivery pipe 282 is formed in a L-shape by an upper stream side piping 291 and a lower stream side piping 292, and a connection direction thereof on an outer surface of a pressure resistance vessel 101 of the compressor and a connection direction thereof with a system piping 400 have different structures. Since piping member bent in an arc shape is not required as the delivery pipe, the substantial build of the compressor can be made small. Consequently, mountability of the compressor on a system can be improved.
