Abstract
A housing and a method of using a liquid for controlling vapor flow through a valve apparatus between a canister and atmospheric conditions. The housing includes a container and a first partition that projects from the housing into the liquid and divides the vapor chamber into first and second vapor sub-chambers. A second partition projects from the container into the first vapor sub-chamber. And a third partition projects from the container into the second vapor sub-chamber. The housing contains the liquid in an upright arrangement of the valve apparatus, and prevents the liquid from flowing out of the container in a non-upright arrangement of the valve apparatus.
