Carbon Dioxide Absorbent Canister with Breathing Gas Temperature and Flow Control.

Abstract

It is a principal object of this invention to provide an improved carbon dioxide scrubber or absorbent canister suitable for prolonged use in closed or semi-closed underwater breathing apparatus systems having a relatively low gas flow rate through the canister. Another object of the invention is to provide such an improved carbon dioxide absorbent canister that occupies the same volume as the canister it replaces while yielding much more complete usage of the absorbent charge capability, and hence a materially longer effective life for a given charge. A canister of the foregoing character is to be provided which is rugged of construction, reliable in operation, and is easier to empty and recharge with absorbent material that those canisters having complex baffles and/or reentrant walls that make it difficult to avoid voids in the bed.
