DEVICE FOR DISTRIBUTION OF GAS IN BAROCOMPLEX COMPARTMENTS Russian patent published in 1997 - IPC

FIELD: diving technology; delivery of conditioned breathing gas mixture to compartments of pressure chambers; supply and distribution of breathing mixture of air to habitable rooms of shipboard and shore objects. SUBSTANCE: gas distribution device includes metal housing with sound-absorbing material with inlet branch pipe fitted with nozzle unit and flow regulator mounted on it. Sound-absorbing material is made from filter elements filling entire volume of housing. Nozzle unit of inlet branch pipe is made from porous gas permeable element. Exhaust grid is of sectional type. It is assembled of porous plates of different density whose throughput capacity is set depending on pressure of gas mixture inside housing; density of plates increases with distance from inlet branch pipe. EFFECT: enhanced efficiency. 1 dwg
