Rail brake damper

A rail brake damper comprising:

• a cylinder-piston arrangement having
• a cylinder,
• a piston that is guided n the cylinder in an axially movable manner and divides the inner chamber of the cylinder into two working chambers,
• a piston rod connected to the piston and guided out of the cylinder at one end thereof in a sealed manner,
• an ejector arrangement, which acts on the piston in such a manner as to slide the piston rod out of the cylinder, and
• a damping device associated with the piston,
• wherein the damping device comprises a damping valve having a piston channel which passes through the piston, thereby connecting the two working chambers, and a closure element associated with the piston channel,
• the closure element being spring-biased in such a manner as to close the piston channel, and hydraulic pressure active in the working chamber remote from the piston rod acting on the closure element in such a manner as to open the damping valve,
• wherein the closure element is formed as a ball that is made of metal or plastic,
• wherein the piston channel is one of a plurality of piston channels connecting the working chambers that pass through the piston, the closure element is one of a plurality of closure elements and each of the piston channels is associated with a separate one of the closure elements,
• wherein the closure elements associated with the plurality of piston channels are associated with a common support plate that is arranged above the piston and that is spring-biased against the closure elements by a valve-biasing spring in such a manner as to close the piston channels, and
• wherein due to the closure elements, there is always a predetermined minimum distance between the piston and the common support plate.
