The invention relates to a bellows accumulator, in particular a pulsation damper, comprising a bellows (3), which, arranged in an accumulator housing (1), separates two media chambers (27, 28) from each other and the bellows folds (19) of which can be moved at least partially along the inner wall (35) of the accumulator housing (1). Said bellows accumulator is characterized in that the outside diameter of the bellows folds (19) is selected to be slightly smaller than the associable diameter of the inner wall (35) of the accumulator housing (1) in such a way that spaces (37, 41) are formed, which together form a hydraulic damping means for at least one medium.
