Valve Spring: Description and Operation

VALVE SPRINGS

DESCRIPTION





The valve springs are made from high strength, chrome-silicon steel (Fig. 15). The springs are common for intake and exhaust applications. The valve spring seat is integral with the valve stem seal, which incorporates a garter spring to maintain consistent lubrication control to the valve stem.

OPERATION
The valve spring returns the valve against its seat for a positive seal of the combustion chamber.
