ABSTRACT:
A seal assembly suitable for static, rotary and reciprocating sealing between the shaft and the housing is provided and includes a seal ring in the shape of an annulus having a body portion with an inside flange and an outside flange extending axially therefrom and establishing a ring seal cavity therebetween. An inside annular spring is disposed in the cavity for biasing the inside flange against the shaft to provide the dynamics seal therebetween. An outside annular spring is also disposed in the cavity for biasing the outside flange against the housing to provide a static seal therebetween and prevent the rotation of the seal ring. A band is disposed in the cavity in between the inside and outside springs for enabling the inside and outside springs to independently bias the inside flange and outside flange, respectively.
