Abstract
A hydraulic accumulator has a first housing shell () and a second housing shell (). The opening edges () of the shells overlap in relation to the longitudinal axis () of the hydraulic accumulator () such that they define a partial volume of the hydraulic accumulator (). The accumulator also has a separating element () separating inner working chambers () from each other within the accumulator housing () in a medium-tight manner. The housing is formed by the housing shells (). The opening edge () of the radially outer-lying housing shell () is positively coupled to the circumference of the radially inner-lying housing shell () by reshaping.
