Piston-cylinder aggregate i.e. gas spring, has piston dividing cylinder into two working chambers that are proximate and distant from closed end comprising opening, and fusible plug arranged in opening

摘要

The aggregate has a piston (2) dividing a cylinder (1) into two working chambers (3, 4) that are proximate and distant from a closed end (7), respectively. A unidirectional piston rod (13) is arranged at the piston, and passes through the working chamber (4). The rod leads from the cylinder concentric to a central longitudinal axis (A) of the cylinder at an end (15) opposite to the end (7). The rod is sealed by a guiding- and sealing device (14). The end (7) comprises an opening (9), and a fusible plug is arranged in the opening. The plug is made of metallic lead or plastic.
