Abstract:
[Problem] To provide a scroll-type compressor with which it is possible to suppress insufficient lubrication of sliding portions of a scroll unit. [Solution] A scroll-type compressor 10 includes: an oil separator 100 which separates lubricating oil from a gaseous refrigerant discharged to a discharge chamber H3; a first lubricating oil chamber H5 which stores the lubricating oil separated by the oil separator 100; a first lubricating oil supply passage which supplies the lubricating oil in the first lubricating oil chamber H5 to a back pressure chamber H6; and a second lubricating oil supply passage which supplies the lubricating oil in the first lubricating oil chamber H5 to the vicinity of an outer end portion of a scroll unit 50. The second lubricating oil supply passage is formed as a passage causing the lubricating oil in the first lubricating oil chamber H5 to pass through a second lubricating oil chamber H7 which is disposed above the first lubricating oil chamber H5 and which is connected to the first lubricating oil chamber H5 by way of an orifice OL3.
