Abstract
An improved throttling bushing for a seal is used in a machine which has a casing and a shaft journaled in the casing. The throttling bushing reduces the flow of cooling and flushing fluid by maintaining a closer tolerance at the throttling bushing by using a labyrinth mounted on the shaft or a sleeve attached to the shaft, and an elastic bushing attached to the casing and positioned around the labyrinth. The clearance between the elastic bushing of the labyrinth is dimensioned to provide noncontact clearance prior to assembly.
