PROBLEM TO BE SOLVED: To provide a fluid machinery capable of reducing oscillation and noise by taking a static balance or a dynamic balance for at least two reciprocation components of fluid supply/discharge mechanism provided at both end positions on the same drive shaft.SOLUTION: In a fluid machinery 1 having two or more fluid supply/discharge mechanisms 2 and 3 provided at both end positions on a same drive shaft 7, each of the fluid supply/discharge mechanisms 2 and 3 having a reciprocation component 36, the reciprocation components 36 of the fluid supply/discharge mechanisms 2 and 3 are disposed to be capable of reciprocating in a same direction; and the fluid supply/discharge mechanisms 2 and 3 are composed by a combination between expansion mechanisms, a combination between pump mechanisms, a combination between a compression mechanism and the expansion mechanism, and a combination between the pump mechanism and the expansion mechanism.SELECTED DRAWING: Figure 1 |
