Abstract

Vorgeschlagen ist ein Tassenstößel (1) eines Ventiltriebs einer Brennkraftmaschine, mit einem an einer Seite durch einen Boden (2) verschlossenen hohlzylindrischen Hemd (3), welcher Boden (2) an seiner äußeren Stirnfläche (4) eine Anlauffläche (5) für einen Nocken sowie an dessen innerer Stirnfläche (6) eine zentrische Anlage (7) für ein Gaswechselventil aufweist, wobei die innere Stirnfläche (6) des Bodens (2) einen radial verlaufenden, planen Steg (8) aufweist, zwischen dessen Kanten (9, 10) die Anlage (7) symmetrisch positioniert ist und wobei sich von jeder Kante (9, 10) ein dachartig vom Boden (2) weg abgeschrägter Schenkel (11, 12) an eine Innenseite (13) des Hemdes (3) erstreckt, welche Schenkel (11, 12) sich achssymmetrisch gegenüberliegen.Proposed is a tappet (1) of a valve train of an internal combustion engine, with a closed on one side by a bottom (2) hollow cylindrical shirt (3), which bottom (2) on its outer end face (4) has a stop surface (5) for a cam as well as on the inner end face (6) of which has a central system (7) for a gas exchange valve, wherein the inner end face (6) of the bottom (2) has a radially extending, projecting web (8) between whose edges (9, 10) the system (7) is symmetrically positioned and wherein from each edge (9, 10) a roof-like from the bottom (2) away chamfered leg (11, 12) on an inner side (13) of the shirt (3) which limbs ( 11, 12) are axially symmetric.

Hierdurch liegt ein Tassenstößel (1) vor, der eine besonders gute Steifigkeit besitzt.

Figure imgaf001
As a result, there is a bucket tappet (1), which has a particularly good rigidity.
