Abstract: A back pressure space of a vane groove having completed communication with an intermediate-pressure supply groove communicates with a first supply section until refrigerant pressure in each of compression chambers having been partitioned by vanes of the vane grooves reach the highest pressure, and then high pressure is supplied from the first supply section. At a time point when the back pressure space having completed communication with an intermediate-pressure supply groove communicates with the first supply section of a high-pressure supply groove, the preceding back pressure space adjacent to that back pressure space on the downstream side of the rotation direction completes communication with the first supply section.
