<P>PROBLEM TO BE SOLVED: To provide a piston mechanism operating with transfer of a fluid, and capable of remarkably expanding a utilization range by obtaining efficiency exceeding even that of a turbine because mechanical friction loss associated with, in particular, movement of a piston is extremely small. <P>SOLUTION: The problem is solved by this piston mechanism including a plurality of eccentric parts in a rotating ring rotatably fitted to an eccentric part of a rotary shaft, and structured such that each eccentric part is arranged with a rotatably fitted ring member, pistons are fixed to both tip parts of a stay part fixed to the ring member, and the pistons are slidably fitted in the cylinders. <P>COPYRIGHT: (C)2013,JPO&INPIT |
