Abstract (en)
[origin: WO2010130332A1] A hydraulic accumulator comprises a first housing shell (2) and a second housing shell (3), the opening edges (5, 6) of which overlap in relation to the longitudinal axis (4) of the hydraulic accumulator (1) in such a way that they define a partial volume of the hydraulic accumulator (1). The accumulator further comprises a separating element (7) which separates inner working chambers (9, 10) from each other within the accumulator housing (8) of the hydraulic accumulator (1) in a medium-tight manner, said housing being formed by the housing shells (2, 3), and wherein the opening edge (5) of the radially outer-lying housing shell (2) is positively coupled to the circumference of the radially inner-lying housing shell (3) by means of reshaping.
