BI-LOBED SEALING ELEMENT AND RETAINER

摘要

An elastomeric sealing device for sealing a fluid opening or passageway at the interface of two mateable parts comprises a bi-lobed elastomeric seal integrally molded on a relatively rigid retainer. The retainer is generally planar in construction with a peripheral load bearing portion that is clamped between the facing sealing surfaces of the mated parts, and an inwardly extending thinner flange portion which is imbedded in the molded bi-lobed seal. The bi-lobed seal is of unitary construction and has a first lobe which extends perpendicularly from one side of the retainer and is sized and shaped to be received in a recess or groove in the sealing surface of one of the mated parts. The seal has a second lobe which extends inwardly and transversely from the first lobe and is sized and shaped to form an interference fit with a boss on the other mated part. The second lobe also includes a generally flat portion closely spaced from the retainer load bearing portion to seal the facing sealing surface of the other mated part.
