ABSTRACT:
A thermal barrier for a diesel engine poppet valve is disclosed. The barrier includes a cup-shaped member having a shield portion spaced from the valve face and a cylindrical skirt portion welded to the valve head. The shield, skirt, and valve face define a hermetically sealed chamber which, when evacuated of gases, provides a heat conduction barrier for insulating the valve face from combusting gases. The chamber is preferably filled with a reinforcing to structurally support the shield and further insulate the valve face. The structural support may be in the form of an insulating material and/or a fabricated material having a low contact area with the shield and valve face.
