REGENERATIVE CANISTER OF SELF-CONTAINED BREATHING APPARATUS Russian patent published in 2011 - IPC A62B19/00 

FIELD: fire-fighting means.

SUBSTANCE: invention refers to regenerative canisters of self-contained breathing apparatuses. A regenerative canister of a self-contained breathing apparatus comprises a sealed container, an internal perforated lidded shell filled with a regenerative product, a central perforated tube and a perforated established in a layer of a regenerative product punched high temperature gas distributor mounted in a layer of the regenerative product. The high temperature gas distributor is coaxial to the central perforated tube and comprises a cylinder formed by three coaxial perforated shells middle of which is corrugated. High temperature gas distributor ends contact to the lid of the internal perforated shell.

EFFECT: enhanced protective properties of the breathing apparatus ensured by optimised volume heat transport of the regenerative product, decreased hydraulic respiratory resistance.
