Abstract
A seal assembly for sealing between a rotating shaft and a housing member is provided. The seal assembly includes a first annular seal member seated in the closed end of an annular axially opening recess rotatable with the rotating shaft and centered radially within the recess by resilient O-ring structure. A second stationary annular seal member is provided and is supported in a floating manner from the housing member or portion and axially shiftable relative to the housing member toward and away from the first annular seal member. The first and second annular seal members include opposing axial faces slidably and frictionally engaged with each other and spring structure is operatively connected between the housing member and the second annular seal member yieldingly biasing the second seal member toward the first seal member. The second floating seal member is radially centered by a resilient O-ring and the seal assembly is constructed whereby fluid pressure between the housing and the shaft will assist in yieldably biasing the second seal member toward the first seal member.
