Abstract
A bellows accumulator has at least one accumulator housing () and a separating bellows () movably arranged in the accumulator housing (). The separating bellowshas a plurality of bellows folds and separates two media spaces () from one another. The stationary open end of the separating bellows () is fixed to the accumulator housing () by a securing device (). The separating bellows () has, at its movable other end, a closure part () having a guide device () by which the closure part () is guided in the accumulator housing (). The closure part () has, in addition to the guide device (), a sealing device (). At least in the one extended end position of the separating bellows (), the sealing device () separates a fluid space (), in which the bellows folds are arranged in the accumulator housing (), from a fluid port () in the accumulator housing (). At least in some of the other working positions, the sealing device () releases this fluid connection.
