Abstract
A fluid machine includes an inflow passageway arranged and configured to introduce fluid from outside into inner and outer fluid chambers of a first eccentric rotation mechanism, a communication passageway arranged and configured to introduce fluid discharged from the inner and outer fluid chambers of the first eccentric rotation mechanism into inner and outer fluid chambers of a second eccentric rotation mechanism, and an outflow passageway arranged and configured to allow fluid discharged from the inner and outer fluid chambers of the second eccentric rotation mechanism to flow to outside. Each of the first and second eccentric rotation mechanisms preferably includes a cylinder, a piston, and a blade. A drive shaft has a main shaft portion and first and second eccentric portions arranged to engage the first and second eccentric rotation mechanisms.
