Abstract
Bei einem doppeltwirkenden Arbeitszylinder mit einem durch ein Arbeitsfluid im Zylindergehäuse in beiden Längsrichtungen verschiebbaren Kolben (4), ist der Kolben mit einer Kolbenstange (7) verbunden, die durch den Deckel (5, 6, 9) des Arbeitszylinders axial nach außen geführt ist, wobei die Kolbenstange (7) hohl ausgeführt ist und koaxial innerhalb der hohlen Kolbenstange (7) eine geschlossene Gasfeder (12) angeordnet ist, die zwischen der Kolbenstange (7) und dem Boden (1) des Arbeitszylinders eingespannt ist.With a double-acting working cylinder with a working fluid in the cylinder housing Piston (4) displaceable in both longitudinal directions, the piston is with a Piston rod (7) connected axially through the cover (5, 6, 9) of the working cylinder is guided outside, the piston rod (7) is hollow and coaxial within the hollow piston rod (7) a closed gas spring (12) is arranged between the Piston rod (7) and the bottom (1) of the working cylinder is clamped.
Um eine Anordnung anzugeben, die sicherer gegen Beschädigungen und in ihrer Funktion ist, weniger Bauraum als die herkömmliche Anordnung beansprucht und in weiterer Folge auch flexibler in der Anpassung und einfacher in Wartung und Reparatur ist, ist die Gasfeder (12) in ein Trennrohr (3) eingesetzt, welches koaxial innerhalb der hohlen Kolbenstange (7) angeordnet und am Boden (1) des Arbeitszylinders befestigt ist. In order to specify an arrangement that is safer against damage and in its function, takes up less space than the conventional arrangement and, subsequently, is also more flexible in adaptation and easier to maintain and repair, the gas spring (12) is inserted into a separating tube (3 ) used, which is arranged coaxially within the hollow piston rod (7) and attached to the bottom (1) of the working cylinder.
