Abstract
Official abstract text for this publication.
A valve member for a poppet valve is provided. The valve member may include a valve stem, a valve head, a face formed on the valve head, a sealing surface disposed between the face and the perimeter of the valve head, a tapered socket, and a bevel. The valve stem may include an outside surface defining a stem diameter. The valve head may include a maximum diameter greater than the stem diameter. The face may be formed on the valve head opposite the valve stem. The sealing surface may include a transition ring disposed between the perimeter of the face and the maximum diameter of the valve head. The tapered socket may be disposed in an end of the valve stem, defining an opening with a socket perimeter sized to receive a spring therein.
