Abstract

Schwingungsdämpfer mit einem durch ein Dämpfmedium betriebenen Endanschlag, umfassend einen Zylinder, in der eine Kolbenstange axial beweglich geführt ist, wobei die Kolbenstange einen Drosselring ansteuert, der ab einer definierten Hublage der Kolbenstange an einer zylinderseitigen Wandung mit reduziertem Durchmesser einen Kompressionsraum begrenzt, wobei der Zylinder mindestens einen mit dem Dämpfmedium gefüllten Arbeitsraum aufweist, der über mindestens eine Drosselöffnung mit dem Kompressionsraum verbunden ist, wobei der Drosselring mindestens einen Druckausgleichskanal aufweist, über den eine in Richtung der zylinderseitigen Wandung weisende Mantelfläche des Drosselrings mit dem Kompressionsraum bezogen auf den Querschnitt des Drosselrings verbunden ist und der Abfluss des Druckausgleichskanals an den Arbeitsraum hubabhängig verschließbar ist.
