<p>PROBLEM TO BE SOLVED: To provide a displacement type rotary compressor appropriate to actual use. SOLUTION: A rotating cylinder member 2 having cylinder chambers 23a to 23d facing to each other with respect to a cavity part 22 formed about a rotation shaft o and a piston holding member 5 rotating about a rotation center position X decentering from the rotation shaft o of the rotating cylinder member 2 are rotatably supported in a casing 6, respectively. Pistons 3 and 4 are held turnably at rotation center positions X1 and X2 decentering from the rotation center position X of the piston holding member 5, the casing 6 is provided with a suction port 61 and a discharge port 62, the rotating cylinder member 2 and the piston holding member 5 are relatively rotated to move the pistons 3 and 4 to discharge through the discharge port 62 fluid sucked from the suction port 61, the suction port 61 and the discharge port 62 are set at predetermined sizes, and the ratio of the number of action times of the rotating cylinder member 2 to the piston holding member 5 and to the pistons 3 and 4 is set 1:2:1.</p> |
