Abstract

A seal assembly comprising: a housing defining a groove; a seal disposed in the groove of the housing; and a coupling element adapted to restrict relative movement between the housing and the seal.

First claim

The invention claimed is:

1. A seal assembly comprising:
a housing defining a groove;
a seal disposed in the groove of the housing; and
a coupling element adapted to restrict relative movement between the housing and the seal, wherein the coupling element is disposed within a bore of the housing and in a bore of the seal, and wherein the bore of the seal passes through an entirety of a tail portion of the seal.

2. The seal assembly of claim 1 , wherein the seal assembly comprises a split seal assembly, and wherein the housing and seal comprise a portion of the split seal assembly.

3. The seal assembly of claim 1 , wherein the seal assembly comprises a first portion and a second portion, and wherein the first and second portions define the same circumferential lengths as compared to one another.

4. The seal assembly of claim 1 , wherein the seal defines a relaxed circumferential length, L SR , and the groove defines a circumferential length, L G , and wherein L SR is greater than L G .

5. The seal assembly of claim 1 , wherein the groove is disposed on a radially inner surface of the housing, and wherein an inner diameter of the seal assembly is defined by the seal.

6. The seal assembly of claim 1 , wherein the bore defines a depth less than an axial length of the housing.

7. The seal assembly of claim 6 , wherein the bore is in fluid communication with the groove of the housing.

8. The seal assembly of claim 6 , wherein the bore defines a central axis oriented generally perpendicular with a depth of the groove.

9. The seal assembly of claim 6 , wherein the coupling element is further disposed in the bore of the seal.

10. The seal assembly of claim 1 , wherein the coupling element comprises a plurality of coupling elements including a first coupling element and a second coupling element.

11. The seal assembly of claim 10 , wherein the first coupling element is disposed adjacent to a first circumferential end of the housing and wherein the second coupling element is disposed adjacent to a second circumferential end of the housing.

12. A seal assembly comprising:
a split housing comprising:
a first portion; and
a second portion, wherein the first and second portions each define a groove;

a split seal comprising:
a first seal element disposed in the groove of the first portion of the split housing; and
a second seal element disposed in the groove of the second portion of the split housing;

a first coupling element adapted to restrict relative movement between the first portion of the split housing and the first seal element of the split seal; and
a second coupling element adapted to restrict relative movement between the second portion of the split housing and the second seal element of the split seal, wherein the coupling element is disposed within a bore of the housing and in a bore of the seal, and wherein the bore of the seal passes through an entirety of a tail portion of the seal.

13. The seal assembly of claim 12 , wherein the first seal element defines a relaxed circumferential length, L SR , and an effective circumferential length, L SE , as measured when the seal assembly is in use, and wherein L SR is greater than L SE .

14. A method of forming a seal comprising:
installing a sealing element into a groove defined by a housing;
coupling the sealing element to the housing to restrict relative movement between the housing and sealing element to form a seal assembly; and
sizing the sealing element after coupling the sealing element to the housing,
wherein the coupling element is disposed within a bore of the housing and in a bore of the seal, and wherein the bore of the seal passes through an entirety of a tail portion of the seal.

15. The method of claim 14 , wherein coupling the sealing element to the housing is performed by a coupling element.

16. The method of claim 15 , wherein coupling the sealing element to the housing is performed by positioning the entire coupling element within a volume defined by an outer diameter of the housing.

17. The method of claim 14 , wherein coupling the sealing element to the housing further comprises:
forming a bore in the housing; and
forming a bore in the sealing element.

18. The method of claim 14 , wherein the seal comprises a split seal including a first half and a second half, and wherein the plurality of bores includes a first bore disposed adjacent to a first circumferential end of the first half and a second bore disposed adjacent to a second circumferential end of the first half.
