In order to isolate a corrosive or reactive fluid in the interior of a dynamoelectric machine from contact with the stator assembly, while avoiding leakage or loss of the working fluid and avoiding contamination of the immediate surroundings and the working fluid in a closed cycle system, and ensuring maintenance-free operation for extended periods of time, the dynamoelectric machine includes a composite shielding member disposed between the stator and the rotor. The composite shielding member is formed of a non-conductive non-magnetic material at least in the region defined by the core of the stator and extending beyond the core at both ends thereof at least into the region defined by the winding of the stator. With this arrangement, the composite shielding member is formed of a non-porous ceramic material facing the rotor to prevent fluid migration therethrough and is also formed of a second material integral with the ceramic material for securing the composite shielding member in a fixed position to define a rotor cavity adapted to receive a fluid therewithin in a manner in which the core of the stator is isolated from the fluid in the rotor cavity.

To transfer a fluid at high service temperature and pressure without the limitations of rigid tubing, a flexible tube is provided with a plurality of generally concentric tubular layers for transferring fluids. The innermost layers define a fluid flow path and provide insulation without pressure containment whereas the outermost layers provide fluid containment and resist pressure exerted by the fluid flowing through the tube. By utilizing a plurality of layers of different materials selected to have specific characteristics, the flexible tube operates at a service temperature and pressure providing a high level of energy transfer.
