PURPOSE:To enable to lubricate the sliding surfaces between scroll vanes of a scroll compressor in a reliable manner, by forming a plurality of small grooves communicated with a suction chamber at the peripheral portion of a vane carrying disk for a revolving scroll vane. CONSTITUTION:A plurality of small grooves 33 communicated with an annular suction chamber 22 is formed equidistantly in the upper surface of a vane carrying disk 14 for a revolving scroll vane 15 at its peripheral portion. These small grooves 33 serve to supply external lubricating oil to the suction chamber 22 by the function of the differential pressure of gas and at the same time to prevent leakage of gas in the suction chamber 22 to the outside, so that it is enabled to lubricate the sliding surfaces between the scroll vanes of a scroll compressor in a reliable manner. |
