Description: |
| Abstract:
A bellows type rotary shaft face seal having coil springs extending between the bellows backing ring and the carrier ring radially outwardly from the bellows and adapted to engage a stationary projection when the bellows is subject to rotation, the engagement acting to increase the tension of the spring to draw the carrier ring away from a rotating shaft face thereby relieving the pressure at the seal interface in response to rotational pressure imparted to the carrier ring. |
