Abstract

See full text

An accumulator device (10) includes at least two accumulator elements (14, 16) that are combined to form a structural unit (12) and that have independently from one another their own accumulator characteristic curves (18, 20), in particular as a result of different preload pressures. The respective accumulator characteristic curves (18, 20) provide a combined total accumulator characteristic curve (22). A fluid can be stored in the structural unit (12) and can be retrieved from it. A hydropneumatic suspension system (24) has such an accumulator device (10).
