  • Carbon canister spring plate
    Patent number: 6321726
    Abstract: A spring compression plate (40), (46), (50), (60) for retaining the active material (28) that adsorbs fuel vapor in a fuel vapor storage canister (16). The plate (40), (46), (50), (60) has a wiper seal (44), (54), (68), (80) around its outer periphery that is capable of moving upwardly or downwardly within the shell body (34) of the canister (16) while maintaining substantial sealing to an inside portion of said shell body (34), thereby preventing leakage of the active material (28) when the canister (34) expands or contracts thermally. The spring compression plate (40), (46), (50), (60) is designed to maintain the integrity of the active material (28) over the lifetime of the vehicle in which it is placed. The spring compression plate (40), (46), (50), (60) also contains perforations (42) , (52), (66), (78) for allowing fuel vapor and air to freely flow through the canister (16).
