Abstract

1. A valve tappet comprising a hollow stem (10, 10', 10") and a base plate (16, 16', 16") having a contact surface (30), said stem and said base plate being connected with one another along a circular ring zone (18, 18') by welding or soldering by means of an energy beam, and also comprising a shield element (22, 22', 22") arranged in the interior of said tappet, said element being located between any region of the ring zone and the region of the ring zone lying diametrally opposite thereto, characterized in that a hollow cylindrical extension (14, 14") of said base plate (16, 16', 16") is butt-jointed with said hollow stem (10, 10', 10").
