Document Type and Number:
Japanese Patent JPH06249088
Kind Code:
A
Abstract:
PURPOSE: To simplify the structure of a canister, reduce the number of parts and miniaturize the canister in a main canister connected in series to a sub- canister by dispensing with an energizing device formed of a spring for pressing an adsorbent in the sub-canister.
CONSTITUTION: A main canister 6 is connected in series to a sub-canister 7. Activated charcoal produced from raw material of wood to have rich elasticity is used for an adsorbent 18 filled in the sub-canister 7. The expansion and contraction of the adsorbent 18 are absorbed by the adsorbent itself. Further, a path interconnecting both canisters 6, 7 is formed with a throttle 26.
