Abstract
A compensating rotary seal assembly adapted to function as a substitute for a stuffing box. The seal assembly includes end plates which may be variably oriented with respect to each other by threaded bolts extending between the plates. The bolts are adjusted to compress an annular elastomeric band defining a chamber between the end plates and also effecting a driving connection between washers and the ends of a sleeve surrounding a shaft, the ends of the washers remote from the sleeve being in a sliding contact with wear surfaces on the end plates.
