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.

Abstract: A seal assembly for sealing a space between a housing and a rotary shaft includes a generally annular sealing member having a central axis and inner and outer circumferential surfaces extending about the axis, at least a portion of the inner surface providing a sealing surface engageable with the shaft outer surface so as to define a seal interface with opposing axial ends. The sealing surface is configured to direct substances entering the interface toward at least one of the axial ends. Further, an annular biasing member is disposed about the sealing member outer surface and configured to exert a radially-inwardly directed force on the sealing member so as to generate contact pressure within the seal interface. The biasing member is arranged on the sealing member such that at least a portion of the biasing member extends axially in general alignment with at least a portion of the sealing surface.

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: A fluid seal assembly (the assembly) of the present invention is disposed between an outer surface, i.e. engine block or any other part that requires application of the assembly and a rotatable member, such as, for example a shaft, wherein the assembly circumscribes the shaft and lubricated the shaft and the same rotates around the axis. The assembly includes at least three members: a casing unit, a sealing ring unit, and a collar. The assembly eliminates problems associated with prior art designs such as static leakage of oil, clogging up the spirals with carbonized oil that negatively impact lifecycle of the fluid seals.
