Abstract
An accumulator device () includes at least two accumulator elements () that are combined to form a structural unit () and that have independently from one another their own accumulator characteristic curves (), in particular as a result of different preload pressures. The respective accumulator characteristic curves () provide a combined total accumulator characteristic curve (). A fluid can be stored in the structural unit () and can be retrieved from it. A hydropneumatic suspension system () has such an accumulator device ().
