ABSTRACT:
A rotary fluid machine includes a first rotation mechanism and a second rotation mechanism. Each of them includes a cylinder having a cylinder chamber and an annular piston which is contained in the cylinder chamber and divides the cylinder chamber into an outer working chamber and an inner working chamber. The cylinder rotates around the piston. The first rotation mechanism and the second rotation mechanism are arranged to be adjacent to each other with a partition plate sandwiched therebetween. The cylinder of the first rotation mechanism and the cylinder of the second rotation mechanism are arranged such that one of the cylinders is provided at one side of a partition plate and the other is provided at the other side of the partition plate. Each of the first rotation mechanism and the second rotation mechanism is provided with a compliance mechanism for reducing a gap that occurs between the cylinders in the axial direction of the drive shaft.
