Abstract: A seal assembly of the present invention is used for sealing a space between a housing and a rotary shaft disposed at least partially within the housing. The seal assembly includes a generally annular sealing member having a central portion and two axially-spaced apart side portions each extending generally radially from the central portion to define a generally annular groove. The assembly includes a generally annular support member disposed within the sealing member groove and configured to retain the central portion disposed generally against the other one of the shaft and the housing. 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.

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.
