PURPOSE:To prevent wear and damage between an Oldham's ring and a brock by forming an oil sump in a position where lubrication is not obstructed by said Oldham's ring, on the top of a projecting part of r receiving said Oldham's ring formed on said block. CONSTITUTION:A projecting part 3a having a groove 3b for receiving the key 6b of an Oldham's ring 6, is formed on the top of the block 3 of a scroll compressor. And, oil sumps 7 are formed on the top of the projecting part 3a and in positions where lubrication is not obstructed by the Oldham's ring 6. By this structure, the sliding area between the bottom face of the annular part of the Oldham's ring 6 and the top of the projecting part 3a of the block 3, can be reduced while enabling sufficient oil to be fed, thereby, preventing the seizing, etc. of said sliding part and damage due to wear. |
