PURPOSE:To enable to lubricate the sliding surfaces between a shroud and a vane carrying disk of a scroll compressor in a reliable manner, by forming an injection port at an outer peripheral portion of the vane carrying disk in the manner that the injection port is communicated selectively with a suction chamber along with revolution of a revolving scroll. CONSTITUTION:An injection port 33 formed at an outer peripheral portion of a vane carrying disk 14 of a revolving scroll 12 is opened at a position where it is communicated selectively with a suction chamber 22 formed in a shroud 21. When the injection port 33 is communicated with the suction chamber 22 along with revolution of the revolving scroll 12, lubricating oil is injected into the gas drawn from a suction pipe 25. Therefore, it is enabled to lubricate the sliding surfaces between the shroud 21 and the vane carrying disk 14 of a scroll compressor in a reliable manner. |
