ABSTRACT:
To create a cup tappet body for valve tappets comprising a cylindrical guide body, a tappet bottom and an element carried by the tappet bottom for holding a valve support, which can be manufactured in as simple a way as possible from wear-resistant materials and is, therefore, inexpensive yet has good wear characteristics, it is proposed that the guide body and the tappet bottom be manufactured as an integral cast connection, and that the element holding the valve support be integrally connected as one piece with the tappet bottom and/or the guide body.
