Valve arrangement for an internal combustion engine and manufacturing method

摘要

The tappet (2) has a central opening (6) to accommodate the end of the valve stem (1). The valve stem and tappet are welded (7) together. The cylindrical skirt of the tappet surrounds the end of the valve spring (3), which bears against the flat end of the tappet (4). A shallow cylindrical depression in the end of the tappet accommodates a shim (5) against which a cam or the end of a rocker may bear.
