ABSTRACT:
In a rotary vane-type compressor the rotor, the housing and the side plates are made of the same kind of material as one another. A plurality of vane grooves the length of each of which is as long as the thickness of the rotor is provided on the rotor. A set of vanes which is made of a different material than the rotor, more particularly a material the coefficient of thermal expansion of which is larger than that of the rotor, is received in the vane grooves in such manner that the end faces thereof face against the side plate. And the width of the vanes longitudinally of the rotor is determined as follows. The width is slightly less than the thickness of the rotor when the temperature there of is less than normal, but when the temperature becomes high the vane width becomes slightly greater than the thickness of the rotor because of the difference of the coefficients of thermal expansion.
