Abstract
A fluid machine includes: a casing having an operating chamber provided in the casing; a pair of rotors rotatably mounted in the operating chamber which have each rotor shaft in each axial direction; an intake opening and discharge opening for fluid and are connected with the operating chamber, respectively; and silencing means provided in at least one of an existing space forming fluid channel on the intake opening side and an existing space forming a fluid channel on the discharge opening side. In the structure, the existing spaces are located between the intake opening and the operating chamber and between the discharge opening and the operating chamber, respectively. Furthermore, at least one among the intake opening and the discharge opening of the fluid where the silencing means is disposed is provided so as to be at parallel with the rotor shafts.
