High pressure seal

1. A seal, comprising:

a support ring having at least one activation port therein;

a sealing ring locked with said support ring to form an enclosed space therebetween, said sealing ring including at least one seal lip; and

an energizer held in said enclosed space and contacting said sealing ring, said enclosed space being open to pressurized media entry on opposite sides of said energizer, said support ring and said sealing ring having an inner radial gap formed therebetween that allows pressure to access said enclosed space, the energizer being forced away from the activation port toward the sealing ring causing a radially inward force on the sealing ring.

2. The seal according to claim 1 , wherein said support ring comprises a rigid material and said sealing ring comprises a sealing material with a lower modulus than said rigid material.

3. The seal according to claim 2 , wherein said support ring comprises at least one of polyether ether ketone, polyimide, polyamide-imide, filled polytetrafluoroethylene, polyphenylene sulfide, polyoxymethylene, polyamide, ultra-high molecular weight polyethylene, polyurethane, and a metal.

4. The seal according to claim 2 , wherein said sealing ring comprises at least one of polytetrafluoroethylene, ultra-high molecular weight polyethylene, polyurethane, and polyester.

5. The seal according to claim 1 , wherein said sealing ring includes a flange that is one of press fit into and clamped to said support ring.

6. The seal according to claim 5 , wherein said support ring is U-shaped and said flange is press fit into said support ring.

7. The seal according to claim 5 , wherein said support ring is L-shaped and said flange is clamped to said support ring.

8. The seal according to claim 7 , wherein said flange includes a raised portion crushed between said support ring and said sealing ring.

9. The seal according to claim 1 , wherein at least one of said support ring and said sealing ring has at least one activation port formed therein that extends into said enclosed space.

10. The seal according to claim 9 , wherein at least one of said support ring and said sealing ring has at least three activation ports formed therein that extend into said enclosed space, said activation ports being equally spaced from one another.

11. The seal according to claim 1 , wherein said at least one seal lip is shaped to have a cross-section with a single contact point.

12. The seal according to claim 11 , wherein said sealing ring includes at least two seal lips, each of said seal lips being shaped to have a cross-section with a single contact point.

13. The seal according to claim 1 , wherein said energizer comprises at least one of an O-ring, a spring, and an elastomeric material.

14. The seal according to claim 1 , wherein said support ring includes a scraping edge on an inner radius of said support ring.

15. A seal, comprising:

a sealing ring having a cavity formed therein and at least one seal lip on an inner radius of said sealing ring, said at least one seal lip being at least partially radially aligned with said cavity formed in said sealing ring, said sealing ring having at least one activation port therein;

an energizer held within said cavity of said sealing ring and biasing said at least one seal lip radially inward, said cavity being open to pressurized media entry on opposite sides of said energizer; and

a support ring locked to said sealing ring, said support ring and said sealing ring having an inner radial gap formed therebetween that allows pressure to access said cavity, the energizer being forced away from the activation port toward the sealing ring causing a radially inward force on the sealing ring.

16. The seal according to claim 15 , wherein said support ring covers one side of said sealing ring.

17. The seal according to claim 15 , wherein said sealing ring includes a flange with a raised portion crushed between said sealing ring and said support ring.
