Abstract

A one-way fill valve for use in electronic enclosures is disclosed. The one-way fill valve allows an inert gas to be added to an electronic enclosure without contamination and without excessive leakage. A scrim layer is provided between a breathable layer and a sealing element to protect the breathable layer from possible rupture and allow for greater air flow across the breathable layer.

Claims (21)

1. A one-way valve for use in an electronic enclosure, the valve comprising:

a breathable top face comprising a porous film;

a bottom face comprising an adhesive material;

a movable sealing element; and

a scrim layer positioned intermediate the sealing element and breathable top face;

wherein the sealing element comprises a film that is releasably secured to the adhesive material.

2. The one-way valve for use in an electronic enclosure of claim 1 , wherein the sealing element further comprises a release coating.

3. The one-way valve of claim 1 , wherein the porous film comprises expanded polyethylene terepthalate.

4. The one-way valve of claim 1 , further comprising an adhesive layer.

5. The one-way valve of claim 1 , further comprising an elastomeric layer intermediate the sealing element and breathable top face.

6. The one-way valve of claim 1 , further comprising an adsorbent intermediate the sealing element and breathable top face.

7. A fill valve for use in filling an electronic enclosure with an inert gas, the valve comprising:

a porous film;

an adhesive material;

a movable sealing element;

a bottom surface; and

a scrim layer positioned intermediate the sealing layer and breathable top face, wherein the adhesive material is disposed between the bottom surface and the sealing element and the adhesive material is in contact with the sealing element.

8. The fill valve of claim 7 , wherein the porous film comprises expanded polyethylene terepthalate.

9. The fill valve of claim 7 , further comprising an adhesive layer for connecting the valve to a wall of an electronic enclosure.

10. The fill valve of claim 7 , further comprising an elastomeric layer.

11. The fill valve of claim 7 , further comprising an adsorbent.
