摘要： PROBLEM TO BE SOLVED: To prevent lowering of compression efficiency and performance, by implementing smooth lubrication between scrolls.
SOLUTION: A scroll compressor has a means 40 for intermittently supplying oil. Lubricating oil press-fed on a rotary bearing 19 side when a turning scroll 29 turns is intermittently fed to an intake side of a pressure chamber by the means 40. The means 40 has: a guide hole 41 disposed in a bottom face of a boss portion 23 of an end plate 21 of the turning scroll 20; and a blowout port 42 whose one end is connected with the guide hole 41 and other end is opened to a side of the end plate 21 of the turning scroll 20. The guide hole 41 is formed on a locus, where a region in slide-contact on a thrust ring 35 according to a turning movement of the boss portion 23 is repeatedly brought into contact with or separated from a region inwardly separated from the above- mentioned region, so that the guide hole 41 intermittently introduces the lubricating oil.

摘要： PROBLEM TO BE SOLVED: To prevent breakage of a sealing member and thereby to implement good sealing performance. SOLUTION: A regulating mechanism 20 for regulating a position in an axial direction of a thrust ring 17 is provided. In the regulating mechanism 20, a stepped portion 21 is formed by cutting out an upper portion of an outer peripheral wall 43 constituting a separation room groove 42, and an extending portion 22 is formed by extending the thrust ring 17 in a radial direction. When a turning scroll 8 pushes down the thrust ring 17 at a time of turning, the extending portion 22 of the thrust ring 17 is engaged with the stepped portion 21, so that a state of the sealing member 16 is kept to be a tolerance or higher, resulting in preventing the thrust ring 17 from pushing down the sealing member 16 to be the tolerance or lower.
