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.Proposed is a tappet (1) for a valve train of an internal combustion engine, with a hollow cylindrical shirt (2), whose one end face (3) with a bottom (5) is connected for a cam contact. It owns that Shirt (2) according to the invention a significantly lower height than the tappets (1) in total, wherein the bottom (5) tapers like a roof from the end face (3) is lifted off.
Aufgrund dieser Ausbildung liegt ein sehr steifer Boden (5) vor, wodurch es gelingt, dessen Dicke (d) signifikant gegenüber bisherig ausgeführten Bodendicken zu minimieren. Due to this design, a very rigid bottom (5) is present, which makes it possible to minimize its thickness (d) significantly compared to previously executed floor thicknesses.
