Abstract

Phasensteller zur Verstellung der Drehwinkelposition einer Nockenwelle relativ zu einer Kurbelwelle einer Brennkraftmaschine, der Phasensteller umfassend:
einen von der Kurbelwelle drehantreibbaren Stator (3) und einen Rotor (7),
eine Frühstellkammer (8) zur Erzeugung eines auf den Rotor (7) relativ zum Stator (3) in Richtung Voreilung wirkenden Drehmoments und eine Spätstellkammer (9) zur Erzeugung eines auf den Rotor (7) relativ zum Stator (3) in Richtung Nacheilung wirkenden Drehmoments,
einen Verriegelungspin (60; 70; 100), der an einem aus Stator (3) und Rotor (7) in eine Ver- und
Entriegelungsrichtung (± L) in und aus einem Verriegelungseingriff hin und her beweglich abgestützt und durch Beaufschlagung mit dem Druckfluid gegen Federkraft aus dem Verriegelungseingriff bewegbar ist,
und eine von dem anderen aus Stator (3) und Rotor (7) gebildete Aufnahme (80; 90; 110), in die der Verriegelungspin (60; 70; 100) im Verriegelungseingriff mit einem bis zu einem freien Ende des Verriegelungspins (60; 70; 100) reichenden vorderen Pinabschnitt (61; 71; 101) und einem vom freien Ende entfernten hinteren Pinabschnitt (62; 72; 102) eingreift und dadurch den Rotor (7) gegen ein Verdrehen relativ zum Stator (3) blockiert,
wobei der hintere Pinabschnitt (62; 72; 102) eine im Verriegelungseingriff in die Aufnahme (80; 90; 110) eingreifende, bis zu einem Öffnungsrand (83; 93; 113) der Aufnahme (80; 90; 110) gemessene Länge (L62; L72; L102) aufweist, die höchstens fünfmal, vorzugsweise höchstens dreimal oder höchstens halb so groß wie die Länge (L61; L71; L101) des vorderen Pinabschitts (61; 71; 101) ist, und die Aufnahme (80; 90; 110) mit jeweils korrespondierender Länge einen im Verriegelungseingriff mit dem vorderen Pinabschnitt (61; 71; 101) überlappenden unteren Aufnahmeabschnitt (81; 31; 111) und einen im Verriegelungseingriff mit dem hinteren Pinabschnitt (62; 72; 102) überlappenden, den Öffnungsrand (83; 93; 113) aufweisenden oberen Aufnahmeabschnitt (82; 92; 112) aufweist.
Entweder weist der vordere Pinabschnitt (61; 101) an einem äußeren Umfang zur Ver- und Entriegelungsrichtung (± L) eine Neigung (α) auf, die über die gesamte Länge (L61; L101) des vorderen Pinabschnitts (61; 101) so groß ist, dass der Rotor (7) nur durch den Eingriff des vorderen Pinabschnitts (61; 101) nicht blockierbar ist, und der Eingriff des hinteren Pinabschnitts (62; 102) die Blockierung bewirkt,
oder der obere Aufnahmeabschnitt (92) weist an einem inneren Umfang zur Ver- und Entriegelungsrichtung (± L) eine Neigung (β) auf, die über die gesamte Länge (L72) des oberen Aufnahmeabschnitts (92) so groß ist, dass der Rotor (7) nur durch Eingriff des vorderen Pinabschnitts (71) in den oberen Aufnahmeabschnitt (92) nicht blockierbar ist, und der Eingriff des vorderen Pinabschnitts (71) in den unteren Aufnahmeabschnitt (91) die Blockierung bewirkt.
