Abstract
A dual spring valve stem seal module utilizes an inner retention spring to incorporate a valve stem seal assembly, a valve spring and a spring retainer. The dual spring valve stem seal module reduces the inventory and simplifies the assembly required for the valve stem seal assembly, the valve spring and the spring retainer, thereby reducing the costs associated therewith. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
