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.

摘要： PROBLEM TO BE SOLVED: To reduce mechanical loss due to seal rings of a back pressure chamber for bearing thrust load acting on a turning scroll of a scroll compressor, while enhancing a seal effect.
SOLUTION: An annular groove 6e is formed in an end plate portion 6a of the turning scroll. The back pressure chamber 19 is defined between the end plate portion 6a and a surface of a middle housing supporting it. Thrust load caused by compression reactive force is counterbalanced by introducing high pressure fluid in the back pressure chamber 19. The two seal rings 11, 12 are provided for preventing leakage of the high pressure fluid from the back pressure chamber 19. These seal rings may be united by a connection portion. The respective seal rings are constructed for movement (slanting in this case) in the annular groove 6e. They, when moving, form annular contact areas of high bearing at portions contacting with a surface of the annular groove 6e or a surface of the associated middle housing, and a high seal effect is obtained while controlling the mechanical loss.

摘要： PROBLEM TO BE SOLVED: To smoothly support a thrust load by rapidly feeding a high fluid pressure to a back pressure chamber immediately after starting in a scroll compressor in which the back pressure chamber having seal rings is formed to support the thrust load acting on a turning scroll.
SOLUTION: An annular groove 6e is formed in the end plate part 6a of the turning scroll and the back pressure chamber 19 is formed in the space thereof from the surface of a middle housing 13. High-pressure fluid is led from a working chamber 9 to support the thrust load generated by a compressive reaction. The seal rings 11 and 12 of the back pressure chamber 19 are axially extended by its thermal expansion and swelling and hinders the operation of the turning scroll 6. Accordingly, if the seal rings 11 and 12 are set small beforehand, the leakage of fluid from the working chamber 9 is increased and the rise of pressure in the back pressure chamber 19 is also delayed because a clearance at the tip of a spiral blade part is increased in starting. To prevent this problem, a sub ring 21 having a groove 6f and functioning as a sliding member is installed to support the thrust load only in starting.

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.
