Telescopic Shock Absorber

Regarding the hydraulic telescopic shock absorbers, a distinction should be made between monotube (gas shock absorber) and twin-tube absorbers.

The telescopic gas shock absorber, also installed in SEAT cars, consists of a cylinder filled with oil where there is a pressing working piston, which has a plug with a small permeable cavity (membrane) at the end. The oil flows through this membrane during the retraction of the piston rod, creating a certain flow resistance. Simultaneously, an underlying gas chamber is compressed. Through this gas cushion, the separating piston is pushed back into its initial position. This damping principle deprives the kinetic energy of the vibrating car and converts it into heat energy.

Shock absorbers provide not only driving comfort, but also perfect driving behavior and good controllability of the car. They substantially increase the road safety of an automobile.
