IMPROVED SNAP-IN CENTER SEAL BUSHING

摘要

A bushing adapted to secure an O-ring seal in position relative to an area of a passage permitting reciprocation of a push rod forms a generally circular bushing body with opposed end faces. The end faces are separated by a gap so as to provide the bushing with an approximately C-shaped structure. The bushing includes a plurality of locking elements resistant to axial loads imposed on the bushing by the push rod disposed at least substantially within a corresponding plurality of recesses distributed around a circumferential exterior of the bushing. Solid ribs are interspersed with the locking fingers to resist radial loads imposed on the bushing by the push rod during operation. The O-ring seal is secured in position within the passage area of the passage by an end surface of the bushing.
