PURPOSE:To allow smooth revolution of the vane of a compressor while suppressing the generation of the side pressure on the vane by preventing the lubricating oil feeding pressure from acting onto the side surface of the vane. CONSTITUTION:The lubricating oil fed under pressure into a pressurization groove 23 is supplied to the base part of each vane groove 9 through the communication groove 24 which is cut on the rotor 8 side so as to face oppositely to the pressurization groove 23. As each vane groove 9 is formed on the outside of the pressurization groove 23 so that the former groove may not overlap with the latter, the feeding pressure of the lubricating oil for the vane groove 9 does not act onto the rear edge surface of the vane 10. Therefor, each vane 10 is allowed to revolved, without being pushed onto the front side plate 5 side by the supplied lubricating oil, and the vane of the compressor can be rotated smoothly. |
