ABSTRACT:
A one-way valve allows air to be drawn from a collapsible, flexible, air-tight bag using a vacuum source. When the vacuum source is removed, the one-way valve prevents air from re-entering the bag. A filter is placed on the valve body to prevent small particles from the bag from clogging the valve or the vacuum source.
