<P>PROBLEM TO BE SOLVED: To suppress an increase in an amount of oil supply to a sliding surface even when a movable scroll has capsized. <P>SOLUTION: A scroll type compressor includes a concave part 82 formed on the sliding surface of an outer edge 62 of a fixed scroll 60, and an oil supply passage 81 formed on an end plate 71 of the movable scroll 70 that opens into the concave part 82 for supplying lubricant to the concave part 82. An effluence end of the oil supply passage 81 that opens into the concave part 82 revolves in the concave part 82 accompanying the revolution of the movable scroll. A blocking part 91 is provided in which a part of the bottom wall of the concave part 82 projects. The blocking part 91 is configured so as to block a part of the effluence end of the oil supply passage 81 in an area of the revolution angle in which the capsizing moment that acts on the movable scroll 70 is a predetermined value or above, and open the entire effluence end of the oil supply passage 81 in the area other than the above area of the revolution angle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
