ABSTRACT:
The circulation of a low temperature cooling fluid is insured by thermal hon effect in a cryoalternator from within a closed loop circuit containing an inner rotating seal of the "bayonet" type with a very small radial gap. Longitudinal and radial piping within the rotor permits internal circulation of cooling fluid by thermal siphon effect across the "bayonet" type rotating inner seal in the absence of positive circulation by leakage of the coolant across the inner seal radial gap.
