MULTISPACED HIGH-PRESSURE BOTTLE Russian patent published in 2007 - IPC F17C1/00 

FIELD: storage of gases.

SUBSTANCE: proposed multispaced high-pressure bottle containing envelopes mainly, of cylindrical or spherical form, nested one in the other with clearance to keep gas in space formed in between, and filling device to intake/discharge gas providing pressure in spaces reducing in steps from maximum pressure P_max in central space to minimum pressure in periphery space. Number of envelopes N corresponds to N=(20-100) P_max/σ_t where σ_t is tolerable stress of material of housing, with equal clearances along middle radii of walls of envelopes equal to ratio of middle radius of wall of peripheral envelope to number of spaces. Envelopes are supported at least by one intermediate support made, for instance, in form of disk with possibility of gas passing. Filling device is made for setting equal pressure differentials on envelope walls in filled up bottle equal to P_max/N.

EFFECT: provision of storage and transportation of gases at very high pressures, improved reliability and simplified technology of manufacture.
