摘要:
A scroll fluid machine with ensured reliability of an oil seal and a bearing even in a compressor operation at high rpm and high load is provided, which includes: a fixed scroll; an orbiting scroll facing the fixed scroll and having a boss provided on a face opposite to the fixed scroll; a drive shaft having a leading end mounted to the boss; an orbiting bearing supporting the drive shaft in connection with the orbiting scroll; and a seal member placed between the boss and the drive shaft to seal against a lubricant supplied to the orbiting bearing. The seal member has an oil lip producing action of moving the lubricant toward the orbiting bearing by rotation of the drive shaft. A communication passage is provided in the oil lip for communication between a space between the orbiting bearing and the seal member and a space outside the boss.
