To provide a variable displacement rotary compressor for varying compression capacity to implement wide band range multistage variable displacement while narrowing rotating speed variation width of a driving motor.
The variable displacement rotary compressor comprises: a housing including a first compression chamber and a second compression chamber each having different capacity; a rotation shaft rotating in the first and second compression chambers; a compression unit selectively performing compression operation in the first compression chamber or the second compression chamber depending on change in rotation direction of the rotation shaft; and the driving motor varying the rotating speed through an electrical control while rotating the rotation shaft in a normal direction or in a reverse direction.
