摘要： A valve stem seal assembly includes an elastomeric sealing member for sealing between a reciprocally moveable valve stem and an associated valve guide in an internal combustion engine. The assembly includes a cylindrical retainer that incorporates an end wall at a first end thereof for securing the elastomeric sealing member to the retainer. The valve assembly is installed over the valve guide, and the retainer is adapted for frictional securement to the guide, whereas the retainer extends down to and engages the surface or deck of the associated engine cylinder head. The retainer includes a radially extending bottom flange at a second end opposite the end wall, wherein the flange bears directly against the cylinder head deck. The upper surface of the flange provides a bearing surface for valve return springs, while the bottom surface of the flange includes an elastomeric sealing media bonded thereto. The sealing media assures positive sealing against oil leakage between the valve guide and the cylinder head deck.

摘要： A valve stem seal assembly incorporates a cylindrical valve stem seal retainer having an axis and an upper end about which symmetrically and circumferentially arranged, alternating upper and lower fingers have depending ends which lie in two distinct planes in one preferred embodiment. The lower fingers depend radially inwardly toward the axis from the cylindrical body of the retainer to provide for axial securement of an elastomeric seal body to the top of a valve guide. The upper fingers extend axially upward from the same end, in the form of a gooseneck, and are adapted to apply a circumferential, radially inwardly directed spring force to the elastomeric seal body. The upper fingers are thus effective to eliminate the garter retainer springs used with conventional seal bodies of traditional valve stem seal assemblies.
