Abstract:
A face seal for forming a sealed condition between two spaced, opposed surfaces, comprising:an inner seal retainer member defining an area having an axis therethrough, the inner seal retainer member having a first axial end portion, an opposite second axial end portion, a plurality of corrugations formed thereon between the first and second axial end portions, and an axial extent as measured between the first axial end portion and the second axial end portion;an outer seal retainer member including a first axial end portion, an opposite second axial end portion, a plurality of corrugations formed thereon between the first and second axial end portions, and an axial extent as measured between the first axial end portion thereof and the second axial end portion thereof, the outer seal retainer member being disposed radially outwardly of the inner seal retainer member defining a space therebetween; andan elastomeric seal member disposed in a predetermined portion of the space between the inner seal retainer member and the outer seal retainer member, the elastomeric seal member having a first axial sealing face, an opposite second axial sealing face, and an axial extent as measured between the first axial sealing axial face and the second axial face when in a free state which is greater than the axial extents of the seal retainer members, and the seal member being deformable so as to conform to said spaced, opposed surfaces for forming the sealed condition and to expand into at least a portion of the space defined between the seal retainer members when subject to a compressive force applied by the spaced, opposed surfaces.
