METHOD OF INDEPENDENT ESCAPE OF PERSONNEL FROM SUBMARINE AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2001 - IPC

FIELD: escape from damaged submarines escape outfit from submarine compartments at increased pressure. SUBSTANCE: proposed method consists in surfacing from depth of damage at continuous bleeding of air from rescue outfit and maintaining pressure in immersion suit at definite depth. During compression to surrounding pressure, 25 to 50% of total volume of put suit is maintained free in under-suit space. Bleeding the air is discontinued at surfacing when surrounding pressure exceeds internal pressure the load-bearing envelope of immersion suit is rated at by 2 to 2.5 times. After surfacing, reducing the pressure is started to atmospheric pressure without keeping the submariner under this pressure. Device used for realization of this method is provided with diaphragm- type relief valve. Above-diaphragm cavity of this valve is communicated with received though seat of depth demand valve. Receiver in its turn is communicated with air volume of immersion suit through check valve. Depth demand valve is provided with interlocking system. EFFECT: enhanced safety; extended field of escape from damaged submarine at minimum possibility of decompression disease. 3 cl, 1 dwg
