Multipart composite valve for an internal combustion engine

摘要

The invention relates to a multipart composite valve for an internal combustion engine, in which a valve shaft ( 2 ) and a valve plate ( 4 ) are embodied separately while being joined together in an overlapping area ( 6 ). The invention is characterized in that at least some parts of the valve shaft ( 2 ) are provided with an intermediate layer ( 8 ) in the overlapping area ( 6 ). Said intermediate layer ( 8 ) forms an integral joint with both the valve shaft ( 2 ) and the valve plate ( 4 ) in the form of a chemical bond, the valve plate ( 4 ) being cast onto the valve shaft ( 2 ).
