<p>A rotary compressor lubricating bearings (32, 34, 45) through a main lubrication passage (51) formed in a drive shaft (17) utilizing the pressure difference in a casing (10), wherein the drive shaft (17) and the bearings (32, 34, 45) are provided with sealing parts (65) of an airtight structure located on the opposite sides in the axial direction of bearing part lubricating passages (59, 60, 61) in order to enhance reliability of the bearings (32, 34, 45) by preventing inflow of high pressure gas to the sliding face of the drive shaft (17) and the bearings (32, 34, 45).</p> |
