Abstract

See full text

A bellows accumulator has at least one accumulator housing (2) and a separating bellows (20) movably arranged in the accumulator housing (2). The separating bellows 20 has a plurality of bellows folds and separates two media spaces (8, 22) from one another. The stationary open end of the separating bellows (20) is fixed to the accumulator housing (2) by a securing device (24). The separating bellows (20) has, at its movable other end, a closure part (36) having a guide device (40) by which the closure part (36) is guided in the accumulator housing (2). The closure part (36) has, in addition to the guide device (40), a sealing device (50). At least in the one extended end position of the separating bellows (20), the sealing device (50) separates a fluid space (8), in which the bellows folds are arranged in the accumulator housing (2), from a fluid port (12) in the accumulator housing (2). At least in some of the other working positions, the sealing device (50) releases this fluid connection.
