Abstract

PURPOSE:To obtain a highly reliable, movable vane type rotary compressor having a simple structure by guiding oil in cooling medium discharged from a compression operating chamber, through an annular groove and a thrust race, so that the oil is used as lubricant oil for a thrust bearing and also used as compressed oil for applying urging force to vanes. CONSTITUTION:Cooling gas medium compressed by the rotation of vanes 14 and discharged from a discharge port 20 to a discharge space, is led through an oil separating element 27 for separating oil therefrom, and then discharged from a discharge port 28 into an evaporator which is not shown, after oil is separated thereform. Meanwhile, the separated oil is led from an oil hole 30 in an R/H plate 3 to an annular groove 32 in a thrust race 15B, as shown by arrow A, due to differential pressure, and then is fed to the root portion of vanes 14 after the oil being subjected to pressure drop by a resistance through a gap between a thrust race 15B and the R/H plate 3.
