Abstract

Vorgeschlagen ist ein Tassenstößel (1) für einen Ventiltrieb einer Brennkraftmaschine, mit einem hohlzylindrischen Hemd (2), dessen eine Stirnseite (3) mit einem Boden (5) für einen Nockenkontakt verbunden ist. Dabei besitzt das Hemd (2) erfindungsgemäß eine deutlich geringere Höhe als der Tassenstößel (1) insgesamt, wobei der Boden (5) dachartig verjüngt von der Stirnseite (3) abgehoben ist.
Aufgrund dieser Ausbildung liegt ein sehr steifer Boden (5) vor, wodurch es gelingt, dessen Dicke (d) signifikant gegenüber bisherig ausgeführten Bodendicken zu minimieren.
