Abstract

Ein Federungszylinder mit einem Zylindergehäuse (10) und einem darin längsverfahrbar angeordneten Trennkolben (64), der einen ersten Medienraum (67) von einem zweiten Medienraum (68) separiert und mit einer im Zylindergehäuse (10) längsverfahrbar angeordneten Kolbenstange (34), die einen dritten Medienraum (74) begrenzt, der über eine Dämpfungseinrichtung (72) mit dem zweiten Medienraum (68) in Verbindung steht, ist dadurch gekennzeichnet, dass die Dämpfungseinrichtung (72) aus zwei Teilkomponenten besteht, die, in Verfahrrichtung der Kolbenstange (34) gesehen, derart hintereinander angeordnet sind, dass in eine Federrichtung der Kolbenstange (34) beide Teilkomponenten (96, 116) und in die der einen Federrichtung entgegengesetzte andere Federrichtung nur eine Teilkomponente (116) die Dämpfung übernehmen.
