| 摘要 |
An inflow passageway (32) for introducing fluid from outside into fluid chambers (61,62) of a first eccentric rotation mechanism (24), a communication passageway (33) for introducing fluid discharged from the fluid chambers (61,62) of the first eccentric rotation mechanism (24) into fluid chambers (63,64) of a second eccentric rotation mechanism (25), and an outflow passageway (31) for allowing fluid discharged from the fluid chambers (63,64) of the second eccentric rotation mechanism (25) to flow to outside, are provided so that a lower-stage fluid chamber and a higher-stage fluid chamber are formed in separate eccentric rotation mechanisms (24,25). |
