摘要： A thrust bearing lubricating system of a swash plate type compressor having a main lubricating oil passageway bored in the center of a drive shaft on which a swash plate is mounted to be axially supported by a pair of front and rear thrust bearings, an oil pumping mechanism for pumping lubricating oil from an oil sump in the bottom of a cylinder block assembly and supplying the lubricating oil into the main lubricating oil passageway, and at least front and rear radial branch lubricating oil passageways formed in the drive shaft to be communicated with the main lubricating oil passageway and to allow spouting of the lubricating oil toward the front and rear thrust bearings, the front and rear radial branch lubricating oil passageways having different cross-sectional areas from one another to equalize an amount of lubricating oil supplied to both thrust bearings.
