Abstract: An annular seal assembly, to seal a chamber of a power cell, includes opposed mating members, a separation plate covering an opening of one of the mating members, and an annular seal for sealing about the separation plate and between the separation plate and each of the adjacent mating members. An exemplary annular seal includes a seal body that is disposed about a longitudinal axis and is configured to receive an outer perimeter edge of the separation plate into a slit of the seal body. The seal in an uncompressed state isolated from the separation plate and the mating members includes opposed axial faces of the slit being biased towards one another. The seal includes bulbous sealing projections disposed at opposite axial sides of the slit that are compressible to seal between the separation plate and the mating members.

Abstract: Sealing gasket construction for providing a fluid seal intermediate a pair of opposed, mating parts or structures. The gasket includes a body formed of a resilient material, and one or more integral compression limiters each received in a corresponding aperture formed through the body. Each of the limiters is formed of a rigid material and extends through the body from a first flanged portion to a second flanged portion with the body being clamping therebetween.
