ABSTRACT:
A seal for the valve stem of a poppet valve in an engine includes an elongated outer tubular body and a concentric inner tubular body with both bodies being connected at one end by a radial flexible web. The inner body is provided with an annular sealing lip for sealing engagement with the stem of the valve while the free end of the outer body has an internal diameter whereby it can sealingly encircle a cylindrical valve guide on the engine for the valve. Preferably a spring is positioned to encircle the inner body whereby to maintain tension of the sealing lip against the outer peripheral surface of the valve stem. A second spring may be positioned on the outside of the tubular body to hold it to the cylindrical valve guide.
