Abstract

A hydraulic telescopic shock absorber wherein damping characteristic can be varied by means of an electromagnetic valve arrangement, the coil of which is accommodated so as to be protected against the hydraulic medium of the shock absorber. The control preferably takes place as a function of the pressure difference between the spaces above and below the piston of the shock absorber.
