Shock absorber

A shock absorber particularly for vehicles which comprises a jacket tube having closed ends, a cylinder formed by said jacket tube, a piston guided in said cylinder inside said jacket tube, a piston rod secured to said piston, said piston dividing said cylinder into two work chambers, at least one flow connection disposed between said two work chambers by way of which at least a portion of a damping fluid flows back and forth between said two chambers, an electromagnetic adjusting device including a magnet coil and an armature confined within and carried by said piston, a control slide connected to said armature and operable to assume a plurality of intermediate positions, said control slide including a first edge (48) having an irregular profile including axially extending protrusions and indentations along an end of said control slide, a position of said irregular profile along said end of said control slide being relative to a second edge (49) fixed on said piston that determines a variable throttle cross section for throttling of a damping fluid inside said at least one flow connection, said throttle cross section formed by said first edge (48) and by said second edge (49) fixed on said piston relative to said control slide permits a portion of the damping fluid to flow between the work chambers, in which fluid is throttled only once in a given flow direction.
