ABSTRACT:
The present invention provides a rotary compressor capable of significantly reducing the loss attributable to mechanical friction. Since an outer rotor 2 is connected via connecting plates 4 to an inner rotor 3, when the outer rotor 2 is rotated by external rotational force, the inner rotor 3 can rotate together with the outer rotor 2 in the same direction. At that time, the rotors 2 and 3 rotate at positions offset relative to each other so that partition pieces 2d on the outer rotor 2 perform circular movement within partition grooves 3b in the inner rotor 3 while turning the connecting plates 4. Thus, the rotors 2 and 3 rotate together, with at least two partition pieces 2d turning all the time along the inner surfaces of the associated partition grooves 3b in a non-contact manner, so that a fluid from an inflow port 1d flows into a space between the rotors 2 and 3 partitioned by the partition pieces 2d and the partition grooves 3b, the fluid being discharged through an outflow port 1e.
