摘要

Lightweight valve comprises a sturdy valve plate (10) provided with a central opening (20) for receiving the end of a valve shaft. The central opening of the plate axially passes through the plate and is limited on the shaft side by a rotational symmetrical shoulder (21) and on the combustion chamber side by a limiting contour (23). The valve shaft is made of a weldable creep resistant material. The end of the shaft on the plate side is extended so that the shaft is prevented from being pulled from the plate. The extension (26) of the shaft is a welded or soldered supporting body (27).
