a Oil compartment

b Gas chamber

Task

Used to compensate for the constantly changing oil pressure during spring deflection and rebound movements of the suspension.

Design

Spherical steel reservoir with oil chamber (a) and gas chamber (b), separated by a diaphragm. The gas chamber is filled to a specific pressure.

Function

Due to the constantly changing oil pressure in the system while driving, e.g. during spring deflection and rebound movements of the suspension, the diaphragm adapts itself to the required chamber volume of the oil in each case. In this process the diaphragm deforms in the spherical housing of the spring actuator.

Location

Rigidly screwed to the body close to the respective spring strut.
