摘要： According to an illustrative example of the invention a cylinder is subdivided by a stationary partition wall into two pressure chambers. A first piston rod is sealingly introduced from atmosphere through one end wall of the cylinder into a first pressure chamber provided on one side of the partition wall. A second piston rod sealingly extends through said partition wall from the first pressure chamber on one side of the partition wall to a second pressure chamber on the other side of the partition wall. A lower gas pressure is provided in the first pressure chamber and a higher gas pressure is provided in the second pressure chamber. Abutment faces are allocated to the first and to the second piston rod. On inward movement of the first piston rod with respect to the cylinder the abutment faces enter into engagement after a predetermined path of inward movement of the first piston rod.

摘要： A piston rod-cylinder assembly, such as a gas spring, includes a cylinder in which a piston rod is axially movable and connecting members on the cylinder and the piston rod for attachment of the assembly in use. The cylinder and an axial portion of the piston rod are covered by a shrink-wrap sleeve for corrosion protection and/or coloration. A lubricant layer is provided between the cylinder and the shrink-wrap sleeve adjacent one or both ends of the cylinder.

摘要： Hinge eye for a piston-cylinder unit, or shock absorber, in particular for air springs, comprising a bracket with an opening, a bearing surface for a connection shank which is connected to a base body, and at least one retaining tab. The retaining tab is actively connected to the piston-cylinder unit and forms a locking connection with a groove of the connection shank. The retaining tab(s) and the part of the hinge eye which forms the opening with the bearing surface are realized in one piece.
