Abstract

A sealing assembly is disclosed for creating a seal between first and second mating members or components. The sealing assembly basically includes a seal retainer with one or more annular seals coupled thereto. The seal retainer including a substantially flat body portion lying in a plane and with at least one resilient retaining element integrally formed with said body portion as a one-piece, unitary member for engaging the seal(s) to retain the seal(s) thereto.

Claims

1. A seal retainer for coupling at least one seal thereto, comprising:

a substantially flat, flexible body portion lying in a plane and with at least one seal receiving aperture; and

at least one resilient retaining element integrally formed with said body portion as a one-piece, unitary member, said at least one retaining element extending inwardly from said body portion into said at least one seal receiving aperture to a free end, said at least one retaining element being resiliently cantilevered relative to said body portion to permit said free end of said at least one retaining element to be resiliently deflected out of said plane of said body to engage a cavity in the seal.

2. A seal retainer according to claim 1, wherein

said body portion includes at least one mounting hole spaced from said at least one seal receiving aperture.

3. A seal retainer according to claim 2, wherein

said at least one mounting hole is shaped and sized for engaging a mounting member to retain said body portion thereon.

4. A seal retainer according to claim 1, wherein

said body portion and said at least one retaining element are constructed of a thin metallic material.

5. A seal retainer according to claim 1, wherein

said body portion has a plurality of said retaining elements with free ends adapted to engage at least one seal.

6. A seal retainer according to claim 5, wherein

a first set of said free ends of said retaining elements lie at points on a first circle in said plane of said body portion.

7. A seal retainer according to claim 6, wherein

a second set of said free ends of said retaining elements lie at points on a second circle in said plane of said body portion.

8. A seal retainer according to claim 5, wherein

said retaining elements are resiliently cantilevered relative to said body portion to permit a seal coupled thereto to be deflected out of said plane of said body portion.

9. A seal retainer according to claim 8, wherein

said body portion includes locating and retaining means for coupling said body portion in a desired location.

10. A seal retainer according to claim 8, wherein

said body portion includes at least one mounting hole.

11. A seal retainer according to claim 10, wherein

said at least one mounting hole is shaped and sized for engaging a mounting member to retain said body portion thereon.

12. A seal retainer for coupling at least one seal thereto, comprising:

a substantially flat, flexible body portion lying in a plane and with at least one seal receiving aperture; and

at least one resilient retaining element integrally formed with said body portion as a one-piece, unitary member, said at least one retaining element extending inwardly from said body portion into said at least one seal receiving aperture to a free end,

said body portion and said at least one retaining element being constructed of a thin material having a thickness ranging from approximately 0.003 inch to approximately 0.005 inch.

13. A seal retainer for coupling at least one seal thereto, comprising:

a substantially flat, flexible body portion lying in a plane and with at least one seal receiving aperture; and

a plurality of resilient retaining elements integrally formed with said body portion as a one-piece, unitary member, each of said retaining elements extending inwardly from said body portion into said at least one seal receiving aperture to a free end,

said retaining elements being arranged for supporting at least two separate seals.

14. A seal retainer according to claim 13, wherein

at least some of said retaining elements are arranged to engage at least two seals.

15. A seal retainer according to claim 14, wherein

said body portion includes at least two separate said seal receiving apertures with at least two said retaining elements arranged in each of said seal receiving apertures.

16. A sealing assembly for creating a seal between first and second members, comprising:

at least one annular seal with first and second longitudinally facing sealing surfaces and an outwardly facing cavity located between said first and second longitudinally facing sealing surfaces; and

a seal retainer coupled to said at least one seal, said seal retainer including a substantially flat body portion lying in a plane and with at least one resilient retaining element integrally formed with said body portion as a one-piece, unitary member for engaging said cavity of said at least one seal to retain said at least one seal thereto, said at least one retaining element being resiliently cantilevered relative to said body portion to permit a free end of said at least one retaining element to be resiliently deflected out of said plane of said body to engage said cavity in said at least one seal.

17. A sealing assembly according to claim 16, wherein

said cavity is a continuous, annular groove.

18. A sealing assembly according to claim 17, wherein

said at least one seal is a circular ring seal.

19. A sealing assembly according to claim 16, wherein

said body portion has at least one seal receiving aperture with said at least one retaining element extending therein.

20. A sealing assembly according to claim 19, wherein

said body portion has a plurality of said retaining elements with free ends adapted to engage said at least one seal.

21. A sealing assembly according to claim 19, wherein

said body portion includes at least one mounting hole spaced from said at least one seal receiving aperture.

22. A sealing assembly according to claim 21, wherein

said at least one mounting hole is shaped and sized for engaging a mounting member to retain said body portion thereon.

23. A sealing assembly according to claim 20, wherein

a first set of said free ends of said retaining elements lie at points on a first circle in said plane of said body portion.

24. A sealing assembly according to claim 23, wherein

said retaining elements are resiliently cantilevered relative to said body portion to permit a seal coupled thereto to be deflected out of said plane of said body portion.

25. A sealing assembly according to claim 16, wherein

said at least one annular seal is a metallic member with a C-shaped cross-section.

26. A sealing assembly according to claim 25, wherein

said body portion has a plurality of said retaining elements with free ends received in said cavity, said free ends being spaced from each other to allow said at least one seal to move laterally within said plane of said seal retainer.

27. A sealing assembly for creating a seal between first and second members, comprising:

at least one annular seal with first and second longitudinally facing sealing surfaces and an outwardly facing cavity located between said first and second longitudinally facing sealing surfaces; and

a seal retainer coupled to said at least one seal, said seal retainer including a substantially flat body portion lying in a plane and with at least one resilient retaining element integrally formed with said body portion as a one-piece, unitary member for engaging said cavity of said at least one seal to retain said at least one seal thereto,

said body portion has at least one seal receiving aperture with said at least one retaining element extending therein,

said body portion and said at least one retaining element being constructed of a thin material having a thickness ranging from approximately 0.003 inch to approximately 0.005 inch.

28. A method of creating a seal, comprising the steps of

providing a thin seal retainer lying in a plane with a substantially flat body portion, at least one seal receiving aperture and at least one resilient retaining element integrally formed with said body portion;

coupling at least one seal within said at least one seal receiving aperture via deflecting said at least one retaining element out of said plane of said body portion such that a free end of said at least one retaining element engages a cavity formed in said at least one seal;

placing said seal retainer with said at least one seal coupled thereto between a first member and a second member; and

coupling said first and second members together such that opposed surfaces of said first and second members engage and compress said at least one seal.
