Abstract:
A valve stem seal assembly has an elastomeric seal with first and second radially inwardly directed sealing lips that are in intimate sealing contact with a valve stem. The assembly also has a metal seal retainer with a first metal seal retainer portion that has a surface axially slanted inward and downward from a top of the elastomeric seal. This slanted portion forms a metal frustoconical foundation with a second metal seal retainer portion that directly radially extends from the metal frustoconical foundation. The axially slanted inward surface of the metal retainer is directly radially outward from the radially inwardly directed first sealing lip.

Claim (Index 17):
The valve stem seal assembly of  claim 16 , wherein the slanted surface of the metal retainer is radially outward from the inwardly directed first sealing lip of the elastomeric seal, the first metal seal retainer portion and the second inwardly directed sealing lip of the elastomeric seal are substantially directed inwardly at an angle \u03b8 from the axis A of the valve stem; and\n wherein a lower portion of the elastomeric seal is in sealing contact and is coplanar with a lower portion of the metal seal retainer and that the metal frustoconical foundation blocks axial stress exerted on the seal from gas pressure in the engine port, so that the axial stress is kept from axially forcing the seal to move axially straight up and inline along the inside surfaces of the retainer, that the seal is prevented from extruding axially upward, and that the frustoconical foundation contains engine gasses of the second sealing lip.
