ABSTRACT:
The specification discloses a rotary machine, providing internal compression or expansion, connectable to a driving or driven shaft and comprising a cylinder rotatable about its axis, a piston within the cylinder rotatable, synchronously with the cylinder, about an axis parallel to but offset from the axis of rotation of the cylinder, cylinder end boundaries contiguous with either the cylinder or the piston, and a series of flexible vanes each of which is insealable rubbing contact with the end boundaries and is sealably connected to the circumferential surfaces of the cylinder and piston, whereby rotation of the cylinder or piston is transmitted by the pull of the vanes to the piston or cylinder, the volume between each adjacent pair of vanes alternately increasing and decreasing during induction and exhaust of the said volume.
