PURPOSE:To provide an improve lubrication in a captioned compressor, by providing a hole extending up and down near vanes of a partition plate interposing between upper and lower cylinders so that contacting parts between rollers and vanes are lubricated. CONSTITUTION:Rollers 9, 10 mounted on each eccentric part 7, 8 of a rotary shaft 3 and upper and lower cylinders 5, 6 which accommodate vanes 11, 12 abutting the rollers 9, 10 are provided on both sides of a partition plte 4. Is provided a through hole 19 which allows high pressure chamber sides 15 of the vanes 11, 12 to communicate with hollow parts 20, 20 composed of the inner peripheral surfaces of the rollers located in each cylinder 5, 7 in opposite to the interposing partition plate 4 and the rotary shaft 3, oil supplying ports 21, 21 for the rotary shaft 3 being opened to the hollow parts 20, 20. Lubrication oil discharged in the hollow parts 20 by the rotation of the rotary shaft 3 is alternately injected to the high pressure chamber sides 15 of the upper and lower cylinders 5, 6 via the through hole 19.
