Abstract
Description
Der Nockenfolger 1 besteht aus einem hohlzylindrischen Gehäuse 2, in dessen Bohrung 3 ein axial zum Gehäuse 2 bewegliches Innenelement 4 eingebaut ist. Das Gehäuse 2 weist an einer Stirnseite 5 eine wälzgelagerte Rolle 6 für einen unmittelbaren Nockenkontakt auf. An einer der Stirnseite 5 gegenüberliegen den Stirnseite 7 ist die Bohrung 3 von einer Anlage 8 des Innenelements 4 für ein Ende einer zeichnerisch nicht dargestellten Stößelstange überragt. Im In nenelement 4 ist ein an sich bekanntes hydraulisches Spielausgleichselement 9 eingebaut.
