PROBLEM TO BE SOLVED: To provide a fluid rotary machine capable of decreasing a dead space as much as possible even if a size of the device is made large by installing a rotary valve just after each of cylinder chambers.SOLUTION: A fluid rotary machine is operated in such a manner that both the first and second head pistons 7, 8 arranged to be crossed within a case body 3 perform linear reciprocating motions within a cylinder 16 under the principle of an inner cycloid and intake and discharging operations are repeated in each of the cylinder chambers 22. A cylinder head part 17 for closing each of the cylinder chambers 22 is provided with each of rotary valves 19 including a suction hole 19a and a discharging hole 19b that are driven and transmitted by a shaft 4, rotated and communicated with cylinder chambers 22 alternatively through communication passages 20a, 20b. The rotary valves 19 cross with the longitudinal axial lines of the opposing pistons 7, 8 and are rotatably arranged in parallel with the output axial lines of the pistons. |
