<p>A rotary fluid machine has an inner rotor (1) and an outer shell (3) held by a stationary support structure, arranged so that sealing points (5) on the inside of the shell (3) interact in a sealing arrangement with the outer surface of the rotor (1) to define working chambers, such that in use the relative motion of the rotor (1) to the shell (3) causes fluid to be moved through ducts (10;11;13) in the rotor (1) and rotor shaft (9), between the working chambers and a point where the rotor shaft (9) interacts with the support structure.</p> |
