Abstract (en)

[origin: EP2735742A1] Provided is a fluid machine that achieves a static balance or a dynamic balance for reciprocating components of at least two fluid suction/discharge mechanisms provided at both end positions of a driving shaft, to thereby enable a reduction in vibrations and noise. A fluid machine (1) includes two or more fluid suction/discharge mechanisms (2) and (3) provided at both end positions of a driving shaft (7), the fluid suction/discharge mechanisms (2) and (3) each including a reciprocating component (36). The respective reciprocating components (36) of the fluid suction/discharge mechanisms (2) and (3) are arranged so as to be mutually reciprocatable in an opposing direction or the same direction.
