Title
(DE) Nockenwellenversteller mit einer Brennkraftmaschine
Abstract
(DE)

Die Erfindung betrifft einen Nockenwellenversteller (1, 51) für eine Brennkraftmaschine, umfassend einen drehfest mit einer Kurbelwelle verbindbaren Stator (5), einen in dem Stator (5) um eine Drehachse drehbar gelagerten Rotor, einen Dichtdeckel (7, 53) zur Leckageminimierung, sowie ein Federelement (9, 59) zur Positionierung des Rotors gegenüber dem Stator (5). Hierbei ist das Federelement (9, 59) über einen Federbügel (3, 41) in axialer Richtung am Dichtdeckel (7, 53) gehalten. Die Verwendung eines Federbügel (3, 41) bietet eine kostenneutrale und gewichtsreduzierte Möglichkeit zur zuverlässigen Positionierung des Rotors gegenüber dem Stator (5).
