TLDR
In this paper, a damper for automatic couplings in railway vehicles has elastic and hydraulic parts, the hydraulic part being double-acting and having two chambers which are interconnected through a variable flow restriction, for example a nozzle formed in part by a shaped axial pin, such that the damping force varies progressively in response to movement applied to the device.Abstract:
