Title (EN) FLUID DAMPER FOR PARTS THAT ARE MOVABLE RELATIVE TO ONE ANOTHER, COMPRISING A PISTON GUIDED MOVABLY IN A CYLINDER
(FR) AMORTISSEUR À FLUIDE POUR PIÈCES RÉGLABLES LES UNES PAR RAPPORT AUX AUTRES AYANT UN PISTON GUIDÉ DE MANIÈRE RÉGLABLE DANS UN CYLINDRE

Abstract:
(EN) The invention describes a fluid damper for furniture parts that are movable relative to one another, said fluid damper comprising a piston (4) guided movably in a cylinder (1) along a longitudinal axis. At least one through-opening (4.1, 4.2) for fluid flowing through is provided in the piston (4) and/or between the piston (4) and cylinder (1). A sleeve (2) is arranged so as to be radially rotatable, relative to the piston (4) against a spring loading, about the longitudinal axis or about an axis running parallel thereto, which sleeve comprises, on its periphery, a number of wings (2.1, 2.2, 2.1', 2.2') corresponding to the number of through-openings (4.1, 4.2). The spring loading is directed such that the wing (2.1, 2.2, 2.1', 2.2') exposes the through-opening (4.1, 4.2) when the piston (4) is stationary in the cylinder (1) and in the event of a movement in a movement direction of the piston (4) and of the cylinder (1) relative to one another along the longitudinal axis, and progressively closes said through-opening in the event of a movement against the movement direction with increasing relative speed between the piston (4) and cylinder (1) along the longitudinal axis. The fluid damper comprises a hollow-cylindrical part of the piston (4), which surrounds the sleeve (2) and the at least one wing (2.1, 2.2, 2.1', 2.2'), which is arranged on the periphery of said sleeve, along at least part of the longitudinal axis thereof.
(FR) L’invention concerne un amortisseur à vapeur destiné à des pièces de meuble pouvant être réglées les unes par rapport aux autres et comprenant un piston (4) qui est guidé de manière réglable dans un cylindre (1) le long d’un axe longitudinal. Dans le piston (4) et/ou entre le piston (4) et le cylindre (1), il est prévu au moins une ouverture de passage (4.1, 4.2) destinée au passage du fluide. Un manchon (2) est disposée de manière à pouvoir pivoter radialement par rapport au piston (4) sur l’axe longitudinal ou sur un axe parallèle à celui-ci en s’opposant à la contrainte d’un ressort, lequel manchon comporte à sa périphérie un certain nombre d’ailettes (2.1, 2.2, 2.1’, 2.2’) correspondant au nombre d’ouvertures de passage (4.1, 4.2). La contrainte du ressort est dirigée de telle sorte que l’ailette (2.1, 2.2, 2.1’, 2.2’) libère l’ouverture de passage (4.1, 4.2) lorsque le piston (4) n’est pas déplacé dans le cylindre (1) et en cas de déplacement dans un sens de déplacement du piston (4) et du cylindre (1) le long de l’axe longitudinal l’un par rapport à l’autre et ferme progressivement l’ouverture de passage en cas de mouvement opposé à la direction de déplacement à mesure que la vitesse relative augmente entre le piston (4) et le cylindre (1) le long de l’axe longitudinal. L’amortisseur à fluide comprend une partie cylindrique creuse du piston (4) qui entoure le manchon (2) et l’au moins une ailette (2.1, 2.2, 2.1’, 2.2’), disposée à sa périphérie, le long d’au moins une partie de son axe longitudinal.
(DE) Es wird ein Fluiddampfer für gegeneinander verstellbare Möbelteile mit einem in einem Zylinder (1) entlang einer Längsachse verstellbar geführten Kolben (4) beschrieben. Im Kolben (4) und/oder zwischen Kolben (4) und Zylinder (1) ist zumindest eine Durchlassöffnung (4.1, 4.2) für durchströmendes Fluid vorgesehen. Eine Hülse (2) ist relativ zum Kolben (4) gegen eine Federbelastung um die Längsachse oder um eine parallel zu dieser verlaufende Achse radial verdrehbar angeordnet, welche an ihrem Umfang eine der Anzahl von Durchlassöffnungen (4.1, 4.2) entsprechende Zahl von Flügeln (2.1, 2.2, 2.1', 2.2') umfasst. Die Federbelastung ist so gerichtet, dass der Flügel (2.1, 2.2, 2.1', 2.2') die Durchlassöffnung (4.1, 4.2) bei im Zylinder (1) unbewegtem Kolben (4) sowie bei einer Bewegung in einer Bewegungsrichtung des Kolbens (4) und des Zylinders (1) entlang der Längsachse relativ zueinander freigibt und bei einer Bewegung entgegen der Bewegungsrichtung mit zunehmender Relativgeschwindigkeit zwischen Kolben (4) und Zylinder (1) entlang der Längsachse fortschreitend verschließt. Der Fluiddämpfer umfasst eine hohizylinderförmige Partie des Kolbens (4), welche die Hülse (2) und den mindestens einen an ihrem Umfang angeordneten Flügel (2.1, 2.2, 2.1', 2.2') entlang zumindest eines Teils ihrer Längsachse umgibt.
