ABSTRACT:
A pneumatic suspension intended for motor vehicles that is equipped with an additional volume. An adjusting piston defining the additional volume separates two work chambers from one another, which can be disconnected from one another or made to communicate with one another via a connecting line and a valve assembly in the connecting line. When the work chambers are in communication, the spring rate of the suspension is variable without force.
