Face Seal With Rotatable Seal King Abstract of the Disclosure A face seal assembly having an intermediate seal ring is disclosed. The intermediate seal ring is disposed between a pair of opposing metal seal faces of the seal assembly so that the faces contact opposite sealing faces on the ring, instead of each other. Means are provided for rotating the intermediate seal ring at a speed which is proportionately less than the rotational speed between the opposing seal faces. This rotation of the intermediate ring reduces the velocities of the contacting seal faces. The face seal assembly is thus capable of use in higher speed applications without incurring scoring of the seal faces.
