ABSTRACT:
A vapor storage canister has an improved carbon bed loading pressure maintenance mechanism. A pressure plate is driven up indirectly, through a threaded shaft turned by a radially wound spiral spring, rather than by an axially compressed helical spring. This takes better advantage of the space available between the carbon bed and the lower end of the canister.
