ROTARY FLUID MACHINE

摘要

A rotary fluid machine has cylinders (21) each having a cylinder chamber (50) and has annular pistons (22) each received in the cylinder chamber (50) while being eccentric relative to the cylinder (21) and partitioning the cylinder chamber (50) into an outer compression chamber (51) and an inner compression chamber (52), and a first rotation mechanism (2F) and a second rotation mechanism (2S) where the cylinders (21) rotate relative to the pistons (22). The first rotation mechanism (2F) and the second rotation mechanism (2S) are arranged adjacent to each other with a partition place (2c) in between. The cylinder (21) of the first rotation mechanism (2F) and the cylinder (21) of the second rotation mechanism (2S) are respectively formed on one side of the partition plate (2c) and on the other side. The first rotation mechanism (2F) and the second rotation mechanism (2S) each have a compliance mechanism (60) for reducing an axial clearance of a dive shaft (33) occurring between the cylinders (21).
