Abstract
An intake valve includes a bladder having a face piece coupled to one end and an opening formed in the other end, a cover attached to the other end of the bladder and having a port coupled to an air reservoir and having a hub coupled to a container, which may be used for pumping air into the bladder when the air in the air reservoir has been consumed. The cover has a check valve for air to flow into the cover when the container is expanded, and for pumping air into the bladder when the container is squeezed. Another check valve may be used for outward flowing of excess air.
