REGENERATIVE CARTRIDGE OF ISOLATING RESPIRATORY APPARATUS Russian patent published in 2003 - IPC

FIELD: isolating respiratory equipment with chemically bound oxygen, particularly regenerative cartridges. SUBSTANCE: cartridge has body with breathing pipe and breathing bag pipe, solid- wall air pipe connected to breathing pipe, regenerating medium interposed between support and press meshes, filter and actuating briquette. Air pipe and actuating briquette are symmetric about plane which is perpendicular to cartridge longitudinal axis. Press mesh springs are coaxial with air pipe axis and actuating briquette axis. Filter is installed into air pipe. Actuating briquette having height of at least 2/3 of regenerative material height is fixed in cylindrical shell. EFFECT: enhanced operating performance. 2 cl, 2 dwg
