Patent number: 9500106Abstract: A valve stem seal utilizes a multi-piece construction to reduce the required manufactured tolerances and/or improve the stress handling capabilities. The valve stem seal can include a first member or can which can be assembled to a second member or spring seat. The can and/or spring seat can have a plurality of axially extending resilient fingers that are biased such that when assembled the fingers are bent against the bias due to the engagement between the can and the spring seat. The fingers on the spring seat allow the spring seat to bend or move relative to the can to accommodate the loading of a valve spring on the spring seat. The use of resilient fingers on the can and/or the spring seat reduces the manufacturing tolerances required for the valve stem seal.Type: GrantFiled: May 20, 2009Date of Patent: November 22, 2016Assignee: Freudenberg—NOK General PartnershipInventors: Rory S.
