ABSTRACT:
To allow a large built-in volume ratio of a vane type compressor, the outer circumferential surface of the rotor is provided in each working chamber with an indentation located next to the leading one of the two vanes partly defining the chamber, thereby increasing the through-flow area of the outlet space of the chamber through which it communicates with the stator's outlet port during the exhaust of compressed gas from the chamber.
