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.

Claims

1. An intake valve assembly comprising:

a bladder including a first end, and including a second end having an opening formed therein,

a face piece coupled to said first end of said bladder,

a cover attaching to said second end of said bladder, said cover including a port for coupling to an air reservoir and for receiving air therefrom, and said cover including a hub provided therein, and

a container coupled to said hub for receiving excess air from the air reservoir, and for pumping air into said bladder.

2. The intake valve assembly according to claim 1, wherein said cover includes a first check valve provided therein and arranged for allowing air to flow into said cover when said container is expanded, and for allowing air to flow into said bladder when said container is squeezed.

3. The intake valve assembly according to claim 2, wherein said cover includes a second check valve provided therein and arranged for allowing the air to flow out of said cover when said container and said bladder have been filled with the air.

4. The intake valve assembly according to claim 1 further comprising a cap attached to said second end of said bladder, said cover being secured onto said cap and including a space formed and defined between said cover and said cap.

5. The intake valve assembly according to claim 4, wherein said cap includes a check valve provided therein and arranged for allowing air to flow into said bladder and for preventing the air from flowing out of said bladder via said check valve.

6. The intake valve assembly according to claim 5, wherein said check valve includes at least one passage formed in said cap, and a valve flap secured to said cap for selectively blocking said at least one passage of said cap.

7. The intake valve assembly according to claim 6, wherein said cap includes a hub provided therein, said valve flap includes a stud extended therefrom and engaged into said hub of said cap for securing said valve flap to said cap.

8. The intake valve assembly according to claim 4, wherein said bladder includes a peripheral flange provided on said second end thereof for forming and defining said opening thereof, said peripheral flange includes a peripheral recess formed therein, said cap includes a peripheral rib extended radially outward therefrom for engaging into said peripheral recess of said peripheral flange and for securing said cap to said bladder.
