Abstract : This patent discloses a face seal for sealing the joint between a rotary shaft and a stationary housing, said seal comprising two sealing discs engaged together through the biasing force of a zero rate spring means. The spring means provides a constant biasing force to maintain a pre-determined sealing engagement force between the discs irrespective of such disturbances as manufacturing tolerances, component assembly errors, service oscillations of the shaft, vibrational effects, or service wear on the sealing discs.
