Conventional dampers

The classic hydraulic gas-pressure shock absorber is used in most automobiles today. Basic principle: The oil column of the monotube gas-pressure shock absorber is held at continuous pressure by an additional volume of gas which is separated by a separating piston. Every shock oil contains about 10% air in a bound molecular gaseous state. The movement of the shock piston within the oil column during deflection and extension results in pressure differences. If the piston rod is abruptly pushed into the interior of the damper due to uneven pavement, pressure increases in front of the piston and decreases behind it. The nitrogen gas of a gas-pressure shock absorber, separated from the oil by a separating piston, keeps the oil column pressurized and thus prevents the bound gas molecules in the shock oil from being released (prevents foaming).

In sum: Only gas-pressure shock absorbers offer drivers constant vibration damping in every driving situation.

For our partners in the automotive industry we are continually developing new solutions in the area of conventional dampers.
