Abstract
A fluid actuated sealing arrangement is provided for use in conjunction with a rotatable member. The arrangement utilizes an actuating fluid for both biasing a rotatable sealing element of the sealing arrangement into sealing association with a portion of the rotatable member and for providing the necessary lubrication to the rotatable sealing element. The sealing arrangement is configured to provide a loading force to the sealing element which is substantially parallel to the axis of rotation of the rotatable member. In a preferred embodiment of the arrangement, the sealing element is adapted to seal a surface substantially normal thereto which is formed as an extension of the rotatable element being sealed.
