Authors Abstract
Content
In order to reduce oil consumption resulting from leakage via valve guides, spring tensioned lip seals are applied.
By the choice of oil side lip contact angle, degree of garter spring leverage, radial sealing force, and surface roughness of the valve stem, the metered oil leakage may be controlled and optimised.
The application of an elastomer with greater wear resistance in a Fluoro-polymer basis (FKM) ensures correct functioning over the working life of vehicle engines.
