The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for the production of a valve comprising:
molding a valve body with a first mold;
preloading the valve body with a second mold;
molding a sealing portion in an open position onto the valve body; and
releasing the preloaded valve body wherein the sealing portion enters a closed position when the preloaded valve body is released, the sealing portion opens when under a fluid pressure, and closes when the pressure is released.
2. The method as in claim 1 further comprising configuring lips of the sealing portion when the sealing portion is in an open position.
3. The method of claim 2 wherein configuring the lips of the sealing portion comprises molding the sealing lips to have a larger sealing surface than a wall thickness of the valve body.
4. The method as in claim 2 wherein configuring the lips of the sealing portion comprises molding the sealing lips to have at least one groove and at least one protrusion wherein the groove and the protrusion interlock when the sealing portion enters the closed position.
5. The method of claim 2 wherein configuring the lips of the sealing portion comprises molding the sealing lips with support ribs in the sealing area.
6. The method as in claim 1 wherein the sealing portion opens on the sides of the sealing portion when under fluid pressure.
7. The method as in claim 1 wherein the sealing portion opens in the center of the sealing portion when under fluid pressure.
8. The method as in claim 1 wherein the sealing portion is made of a flexible elastomer.
9. The method of claim 8 wherein the flexible elastomer is one of rubber or silicone based.
10. The method of claim 1 wherein the valve body comprises a substantially rigid skeleton.
11. The method of claim 10 wherein the substantially rigid skeleton is one of a plastic or metal.
12. A method for the production of a valve comprising:
molding a valve in an open position;
reversing the valve to a closed position with a substantially rigid skeleton; and
affixing the substantially rigid skeleton onto the valve wherein the substantially rigid skeleton keeps the valve in the closed position.
13. The method of claim 12 further comprising configuring lips of the sealing portion when the sealing portion is in an open position.
14. The method of claim 13 wherein configuring the lips of the sealing portion comprises molding the sealing lips to have a larger sealing surface than a wall thickness of the valve body.
15. The method as in claim 13 wherein configuring the lips of the sealing portion comprises molding the sealing lips to have at least one groove and at least one protrusion wherein the groove and the protrusion interlock when the sealing portion enters the closed position.
16. The method of claim 13 wherein configuring the lips of the sealing portion comprises molding the sealing lips with support ribs in the sealing area.
17. The method of claim 12 wherein affixing the substantially rigid skeleton onto the valve comprises molding the rigid skeleton onto the valve.
18. The method of claim 12 further comprising molding the rigid skeleton separately from the molding of the valve.
19. The method of claim 12 wherein affixing the substantially rigid skeleton onto the valve comprises building the substantially rigid skeleton into the valve.
20. A method for the production of a valve comprising:
molding a first part of a valve with a first material; and
molding a second part of the valve with a second material wherein the first material and the second material are dissimilar materials such that the first and second materials do not bond to each other and wherein the first part and the second part are mechanically bound together at at least one point.
21. The method as in claim 20 wherein the first material is a substantially rigid material and the second material is a substantially flexible material.
22. A method for the production of a valve comprising:
providing a preloaded substantially rigid housing; and
overmolding the preloaded substantially rigid housing with a substantially flexible material wherein the substantially rigid housing is released from its preloaded state after the substantially flexible material is overmolded thereon, the substantially flexible material forming a valve that enters a closed position when overmolded onto the substantially rigid housing.
23. The method as in claim 22 wherein the substantially rigid housing is spring loaded.
