摘要:
A buffer, particularly suitable for use in railway vehicles, comprising a cylinder including a movable piston and a buffer fluid contained therein, the buffer fluid formed of a very high-viscosity fluid such as silicone oil, and at the same time the cylinder includes a gaseous medium having a volume at least corresponding to the displacement of the piston rod of the piston when it moves in the cylinder to the end of its stroke.
