Abstract: 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.

Abstract: An equalization device is, in particular, in the form of a tank. The housing (2) of the tank has at least one inlet (8) and one outlet (10) for receiving and discharging fluid, respectively, at least in one of the housing walls (4) of the housing, which housing can be filled with the fluid. At least one equalization body (14) is arranged within the housing (2). The equalization body is at least partly provided with an elastically compliant separating wall (20). The interior of the equalization body is delimited, and is at least partly in pressure-equalizing connection (32) with the surroundings at a passage (12, 32) through one of the housing walls (4).

Abstract: A safety device includes a connection point (21) for a pressure accumulator (1) that is connected to a bursting unit (55) at the gas end via the connection point (21). The bursting unit (55) can be triggered by a controllable force element (73). In the triggered state, the bursting unit allows the pressure accumulator (1) to be emptied at the gas end.

Abstract: A damping device, particularly for damping or avoiding pressure surges such as pulses, in hydraulic supply circuits, preferably in the form of a silencer, includes a damping housing that surrounds a damping chamber (19), has at least one fluid inlet (11), has at least one fluid outlet (13) and has a fluid receiving chamber (19) extending between the fluid inlet (11) and the fluid outlet (13). During operation of the device, a fluid flow crosses the damping chamber (19) in a through-flow direction (15), coming from the fluid inlet (11) in the direction of the fluid outlet (13). At least parts of the fluid receiving chamber (19) extend in at least one extension direction transversely with respect to the through-flow direction (15). The fluid receiving chamber (19) immediately adjoins the fluid inlet (11) and the fluid outlet (13) and is delimited by at least one yielding wall part (4).

Abstract: A bellows accumulator, in particular a pulsation damper, includes a bellows (3) arranged in an accumulator housing (1) and separating two media chambers (27, 28) from each other. Bellows folds (19) of the bellows can be moved at least partially along the inner wall (35) of the accumulator housing (1). The outside diameter of the bellows folds (19) is selected to be slightly smaller than the associated diameter of the inner wall (35) of the accumulator housing (1) in such a way that spaces (37, 41) are formed, which spaces together form a hydraulic damper for at least one medium.

Abstract: A damping device for damping or avoiding pressure surges, such as pulses, in hydraulic supply circuits has a damping housing (1) surrounding a damping chamber and having a fluid inlet (35) and a fluid outlet (41). A fluid receiving chamber extends between the fluid inlet (35) and the fluid outlet (41). During operation of the device, a fluid flow crosses the damping chamber in a throughflow direction (11), from the fluid inlet (35) to the fluid outlet (41). Parts of the fluid receiving chamber extend transversely with respect to the throughflow direction (11). More than one fluid receiving chamber is arranged one after the other in the throughflow direction (11). The fluid receiving chamber that is first upstream and the fluid receiving chamber that is last downstream immediately adjoin the fluid inlet (35) and the fluid outlet (41), respectively.

Abstract: A piston accumulator has a dividing piston (22) inside an accumulator housing (2) that separates a chamber (28) containing a working gas, such as nitrogen, from a chamber (26) containing a working fluid, such as hydraulic oil. The dividing piston (22) is longitudinally movably guided in a guide tube (24). The guide tube (24) is arranged inside the accumulator housing (2) and extends at least partially along the housing longitudinal axis (10).
