    Abstract: A seal assembly is for sealing between a housing and a rotary shaft includes an annular sealing member coupled with the housing and having inner and outer circumferential surfaces and a plurality of projections extending radially from the outer surface and spaced circumferentially about a central axis. Each projection has first and second axial ends and the plurality of projections define first and second projections. An annular biasing member is disposed about the sealing member outer surface and exerts an inwardly directed force on the sealing member. The biasing member has first and second ends and is arranged on the sealing member with the biasing member first end contacting the second end of each first projection and the biasing member second end contacting the first end of each second projection. As such, the biasing member extends axially and circumferentially between the first and second projections.

    Abstract: A seal for sealing a space between a shaft and a housing, includes a base member coupled with one of the housing and the shaft and a generally annular, elastomeric sealing member sealingly contactable with the other one of the housing and the shaft. The sealing member is coupled with the base member such that the sealing member is circumferentially strained to reduce friction between the sealing member and the other one of the housing and the shaft. The seal assembly is preferably formed by providing a base member having a generally annular carrier portion and a generally annular, elastomeric sealing member, coupling the sealing member with the annular portion of the base member, and plastically deforming at least a section of the base member carrier portion such that the sealing member is circumferentially strained.

    Abstract: An accumulator piston for an automatic transmission. The piston comprises two components, the first and second being cup elements welded together with their closed ends in abutting relation. The lower cup includes a curled back portion with a radial flange having an axially extending bi-directional oil seal thereon, and spaced apart recesses in the curled back portion to permit oil to flow therein. The upper cup includes a radial flange of reduced diameter compared to the lower cup flange. The flange also has a lip seal thereon. The piston is spring-loaded and moves up and down in a bore and counterbore in response to fluid flow on either side of the piston to absorb shifting shocks.
