機。A rotor having radially slidable vanes in independent slits is rotatably supported in a cylinder chamber formed by attaching front and rear plates to both end faces of a generally cylindrical cylinder. , A lubricating oil supply groove is provided on the inner surface of one plate that communicates with the slit bottom only when the vane tip passes near the discharge hole, and on both plate inner surfaces, the slit bottom completely connects the lubricating oil supply groove. After passing, an arcuate groove communicating with the slit bottom is formed, and these arcuate grooves and lubricating oil supply grooves are communicated with medium-pressure and high-pressure lubricating oil supply passages, respectively, and furthermore, the starting end and the terminal end of the arcuate groove are brought into communication with each other. A conductive groove is formed, and this conductive groove is located outside the inner end of the vane when the tip of the vane is located near the discharge hole, and the outer diameter of the circular arc groove and the conductive groove are the same, and the conductive groove and the slit bottom are A vane type compressor, characterized in that the communication between the slit bottoms gradually decreases from the terminal end of the arcuate groove to the lubricating oil supply groove.
