Zusammenfassung: | A fluid machine (1a) includes a multi-stage compressor (6), a pressure container (10), a first supply path (11), a pump (12), a first return path (15), and an intermediate pressure space (20). The multi-stage compressor (6) includes a first compressor (6a), a second compressor (6b), and a bearing (7). The pressure container (10) stores a liquid lubricant whose main component is the same kind of substance as a main component of a refrigerant. The first supply path (11) is a flow path for supplying the liquid lubricant to the bearing (7). The pump (12) is disposed on the first supply path (11). The first return path (15) is a flow path for returning the liquid lubricant that has passed through the bearing (7) to the pressure container (10). The intermediate pressure space (20) is filled with a gas refrigerant at an intermediate pressure. The internal space of the pressure container (10) constitutes a part of the intermediate pressure space (20). |
