ABSTRACT:
A shock absorber with frequency-selective action, in particular for motor vehicles, can have a working cylinder filled with a damping fluid and divided into two working chambers by a piston which has throttle valves and is fastened to a piston rod. For optimal damping adjustment in vehicle-relevant frequency ranges, the working cylinder can preferably be provided with at least two hydraulic capacitances, one of which can be connected to the lower working chamber by way of a hydraulic inductance.
