ABSTRACT:
A seal apparatus is provided for sealing a fluid in a stationary housing apparatus having an orifice through which a rotatable shaft extends. A bearing member with an optically flat bearing surface rotates with the shaft inside the housing. A rotationally static bearing, also having an optically flat bearing surface, extends into the housing and surrounds the shaft so that the respective optically flat bearing surfaces are positioned adjacent to each other to form a dynamic seal. The dynamic seal is maintained by external apparatus which continuously applies a uniform pressure to the static bearing thereby forcing its optically flat bearing surface against the rotating optically flat bearing surface. The junction between the stationary housing apparatus and the rotationally static but axially movable bearing is sealed by an "O" ring seal held in a circumferential groove around a cylindrical surface defining the orifice in the housing through which the rotationally static bearing extends.
