ABSTRACT:
An improved vapor storage canister includes a single fill purge tube that extends down through the bed, nearly to the bottom of a reservoir in the center of a cone shaped shell enclosing the bottom of the canister. Liquids entering the canister are consolidated and collected at the bottom, and drawn out first during purge, to protect the bed from contamination. The working of the absorbent bed is more efficient, since the vapors concentrate toward the bottom, where the purge point is, and since purge air is drawn in through the same pattern in which vapors were initially absorbed during fill.
