Abstract
A seal assembly for sealing about an axis of rotation has a pair of seal rings relatively rotatable about the axis while in face engagement radially of the axis. One of the seal rings is yieldably pressed against the other, which is held by axially fixed clamping members at axially opposite sides thereof and has a substantially different coefficient of expansion than the clamping members. The clamping members have oppositely directed retainer surfaces annular about the axis, each paired with an opposed parallel surface on the clamped ring. Each pair of retainer and opposed surfaces is inclined at an acute angle to the other pair with its surface generatrices centered on substantially the same point on the axis as those of the other pair to minimize distortion of the radial plane of engagement of the rotary seal faces by relative expansion/contraction of the clamped ring and clamping members.
