ABSTRACT:
A vessel designed for deep-sea diving or for outer-space exploration has a hull divided into a multiplicity of concentric spherical shells separated by clearances in which air or some other fluid is maintained at a pressure constituting a fraction of the overall pressure differential between the interior of the vessel and the surrounding body of water or empty space. The fractional pressures, whose sum equals the overall differential, can be maintained by valves closing whenever the predetermined fractional differential of the respective clearance is reached; alternatively, a controller responsive to signals from individual pressure sensors in the several clearances can control a pressure pump with separate outlets to these clearances.
