摘要： The invention relates to a hydraulic accumulator, in particular a bladder accumulator, comprising two at least partially adjacent plastic casings (12, 14). The first plastic casing (12) comprises a collar part (16) at least at one end thereof. The aim of the invention is to produce a leakproof accumulator arrangement which is economical to produce. To achieve this, a gap opening (24) between the casings (12, 14) extends up to a point, at which the casings (12, 14) are positioned together in a coaxial manner, and a disk valve (50) is provided as a valve for controlling the supply and discharge of the medium in the opening (10).

摘要： The invention relates to a piston-type accumulator comprising a separating piston (24), which can be axially displaced inside an accumulator housing (10) and which separates two spaces from one another inside the accumulator housing (10), particularly a gas side (22) from a liquid side (20) of the accumulator. Due to the fact that the separating piston (24) is predominantly or completely made of a plastic material, it can be provided with a very light weight whereby reducing the overall installation weight of the piston-type accumulator.

摘要： The invention relates to a hydraulic accumulator with an accumulator housing provided in the form of a tube (1), inside of which a separating element, preferably a separating piston (9), which can be displaced in the axial direction (7) of the tube, separates pressure chambers (13, 15) located on either side of the separating piston. In addition, the tube (1) is closed at at least one end by a cover-like closing part (5) having a contact surface for joining to the respective end edge of the tube (1). The contact surface has a flat part provided in the form of an annular surface (39), which projects inside the tube (1) and which serves to positively brace the tube wall against radial forces, and the contact surface has an annular surface (41), which extends in a radial direction and which serves to positively brace the tube wall against axial forces.

摘要： The invention relates to a piston-type accumulator comprising an accumulator housing provided in the form of a cylinder tube (1), inside of which a separating piston (15), which separates two working spaces (5) and (6) from one another, can be displaced in an axial direction within a piston stroke area (19) of the cylinder tube (1), which is closed at both axial ends by a closure part (7) of which at least one, by deforming a deforming area (9) of the wall of the cylinder tube (1), said deforming area adjoining the piston stroke area (19), is provided in the form of part that exists as a single piece therewith. A stop body (25), which limits the movement of the separating piston (15) before reaching the deforming area (9), is provided inside the cylinder tube (1) at the location where the piston stroke area (19) transitions into the deforming area (9).

摘要： The invention relates to a method for producing an accumulator bladder for a hydraulic accumulator, which is formed from at least two parts (24, 26) that, by means of a joining means, are joined to one another along a joining surface under the action of an energy medium (36). The aim of the invention is to provide that the joining means have an energy accumulation medium, which at least partially accumulates the energy introduced by the energy medium (36) and releases it to the joining material. To this end, the invention provides a method for producing an accumulator bladder for a hydraulic accumulator, which ensures a high process reliability and which enables the creation of high-quality seam locations and the reduction of the process time for joining the accumulator bladder parts to one another.
