ABSTRACT:
A hydraulic damper is designed, for example, as a piston/cylinder unit. The arrangement has a part (for example, a piston) forming a vibrational system by means of a spring. Vibrations acting on the damper arrangement are greatly attenuated virtually only in the resonant range of this vibrational system, because only in this case can vibrations of high amplitude be excited and a high dissipation of energy by way of hydraulic flows in channels and between cylinder chambers take place.
