Patent ID: 6918592

Claim:
A face seal device for sealing a shaft relative to a casing, including a pair of co-operating seal rings, one of said seal rings serving for non-rotational mounting on the casing and the other of said seal rings serving for common rotation with the shaft, said seal rings including bores through which the shaft is extended when in operation, said seal rings being held in radial alignment with the shaft by a mounting member, and said seal rings being held in an operational positional relationship of each other by a pair of axially spaced axial stops on the mounting member between which the seal rings are disposed, one of said axial stops engaging the non-rotational seal ring and the other of said axial stops engaging the rotating seal ring, wherein said mounting member is axially movable relative to said seal rings when an external axial force is applied to the mourning member, in that said other axial stop engaging the rotating seal ring is held radially resiliently for moving said other axial stop from engagement with said rotating seal ring, for withdrawing said mounting member from said seal rings; wherein the seal rings are provided in a final operational position after the mounting member is withdrawn.
