Abstract

Die Erfindung betrifft einen Tassenstößel für eine Brennkraftmaschine mit einem Hemd (4) und einem Verdrehsicherungselement (6), welches in eine radiale Ausnehmung (5) des Hemdes (4) eingesetzt ist und die Orientierung des Hemdes (4) gegenüber einer Bohrung des Zylinderkopfes um eine Hubachse bestimmt.
Ein bei Gewährleistung der gewünschten Sicherungsfunktion besonders kostengünstig herzustellendes Verdrehsicherungselement ergibt sich erfindungsgemäß, wenn dieses eine in Umfangsrichtung zu einer Längsachse L-L umlaufende Wandung aufweist. Zumindest eine Stirnfläche (27) der Wandung (24) ist an der äußeren Mantelfläche des Hemdes (4) radial nach innen abgestützt. Die Wandung (24) weist mehrere Fortsätze (9, 10) auf, die sich durch die Ausnehmung (5) erstrecken und einen Absatz (25, 26) besitzen, der in die Ausnehmung (5) eingeklipst wird und sich an der inneren Mantelfläche des Hemdes (4) radial nach außen abstützt.
