Abstract (en)
[origin: WO2022207033A1] The invention relates to a rail vehicle fluid damper and to a method for monitoring said fluid damper, wherein a reference piece (9) is placed inside a housing (2) of the damper (1), and the deformation of the reference piece (9) is measured, and a conclusion can be drawn about the change in pressure, thus allowing a pressure of the fluid medium (7) in the housing (2) to be monitored.
