摘要： PROBLEM TO BE SOLVED: To provide the sure sliding movement by constituting an oil supply mechanism with a simple structure when constituting bearing parts 51 to 54 of a small and inexpensive sliding bearing. SOLUTION: A compression mechanism part C has an oil storage part 55 of a low pressure refrigerant atmosphere arranged in a compression mechanism part upper part for storing lubricating oil, a refrigerant passage 57 for passing a refrigerant and an oil pump 60 for feeding the oil to the bearings 51 to 54 by sucking the lubricating oil stored in the oil storage part 55. Thus, the oil storage part 55 can be arranged on the low pressure side. Since the low pressure side is the suction atmospheric temperature, the deterioration in oil in a high temperature atmosphere and reduction in a refrigerant flow rate caused by heating the refrigerant by mixing the high temperature oil with the suction refrigerant, can be prevented. The sure sliding movement can be provided even if the bearing parts are constituted of the sliding bearing by stably supplying the lubricating oil by falling of the oil by dead weight and the simple oil pump 60.

摘要翻译：要解决的问题：当构成小而便宜的滑动轴承的轴承部分51至54时，通过构成具有简单结构的供油机构来提供可靠的滑动运动。解决方案：压缩机构部分C具有设置在用于储存润滑油的压缩机构部上部的低压制冷剂气氛的储油部55，用于使制冷剂通过的制冷剂通路57和供给用油泵60 油通过吸入存储在储油部55中的润滑油而进入轴承51〜54。因此，储油部55可以配置在低压侧。由于低压侧是吸入大气温度，因此可以防止高温气氛中的油的劣化以及通过将高温油与吸入制冷剂混合来对制冷剂进行加热而引起的制冷剂流量的降低。即使轴承部件由滑动轴承构成，也可以通过将油体通过自重下降稳定地供给润滑油和简单的油泵60来进行确定的滑动运动。（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a scroll-type compressor 100 capable of improving the efficiency of the compressor by reducing the sliding loss and the back pressure leakage at seal rings 18.
SOLUTION: A back pressure mechanism part is configurated by a plurality of small diameter back pressure chambers 19 and the small diameter seal rings 18. Whereby the deformation by thermal expansion of the seal ring itself and the swelling caused by a refrigerant in a case of a resin, and the impairing of the rigidity can be minimized. Further the deformation and torsion of the seal ring causing a problem at the sliding part with a revolving scroll 6 in operation, are hardly found. Further as each of the seal rings 18 can follow and absorb the distortion generated at a revolving scroll 6 side, the increase of the sliding loss caused by the rise of face pressure by the distortion can be prevented, and the sealing performance can be secured even by a high-pressure refrigerant such as carbon dioxide. Whereby the sliding loss and the back pressure leakage at the seal rings can be reduced, and the efficiency of the compressor can be improved.

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.
