Abstract: A shaft seal assembly for sealing along a rotor shaft is provided. The shaft seal assembly includes a seal housing, annular inner and outer seal members, an annular middle element, and an end plate. The seal housing has a seal member bore and a shaft bore. The annular inner and outer seal members are configured to be disposed in the seal member bore. The middle element is disposed between the inner seal member and the outer seal member within the seal member bore. The end plate is attached to the seal housing and covers a portion of the seal member bore. The middle element biases the inner seal member against the seal housing and biases the outer seal member against the end plate.
