Abstract
A device for increasing shock absorption by hydraulic means in the terminal section (19 & 27) of hydraulic shock absorbers with a shock-absorption piston (3) that divides the shock absorber into two compartments. The width of a channel that conveys hydraulic fluid through the piston is reduced by partly blocking the access of fluid thereto. The access comprises several individual accesses that do not mutually communicate. To ensure precise and constant increased shock absorption in the vicinity of the buffers, one or more individual accesses are completely blocked.
