Abstract

Selbstpumpendes Federbein mit innerer Niveauregelung, beispielsweise für Kraftfahrzeuge, mit einem fluidgefüllten, unter dem Druck des als Feder wirkenden Fluids stehenden Arbeitszylinder (19), in dessen Arbeitsraum (3, 31) eine hohle Kolbenstange (1) abgedichtet geführt ist, in die ein am Arbeitszylinder (19) befestigter Pumpenkolben (4, 6) abgedichtet hineinragt, der bei Relativbewegungen zwischen dem Arbeitszylinder (19) und der Kolbenstange (1) Fluid aus dem Arbeitsraum (3, 31) in eine unter höherem Fluiddruck als im Arbeitsraum (3, 31) stehende Druckkammer (13) fördert, und mit Strömungsverbindungen (5, 17, 18, 32) zwischen der Druckkammer (13) und dem Arbeitsraum (3, 31) zum wahlweisen Einstellen eines vorgebbaren, dynamischen, durch die Ausfahrlänge der Kolbenstange (1) bestimmten Niveaus, wobei die Kolbenstange (1) zum wahlweisen Zusammenwirken der axial und umfangsbezogen beabstandeten Strömungsverbindungen (5, 17, 18, 32) mittels einer Drehvorrichtung (33) drehbar ist.
