Abstract

The sealing ring (5) is particularly intended for sealing and metered lubrication of a valve stem guide (1) and is of the type consisting of an elastomer with a securing portion (8) fitting on the end (3) of a stem guide, the ring (5) being vulcanised to an outwardly flanged metal reinforcing ring (7) and being provided with a spring-loaded sealing lip (9). The reinforcing ring extends axially above the securing portion where it is provided with axial slots to form a number of radially sprung tongues (12). Some of the tongues (13) are shortened and bent radially outward. The reinforcing ring may be formed from a length of tube. The tongues (13) may alternate with the tongues (12).
